viiN2-X Ethernet Extender Installation and Operation ManualWelcome!Welcome to the Wireless, Inc. N2-ACCESS™ Series product family. This manual is designedto introduce you to the N2-X Ethernet Extender™, and to provide you with information necessaryto plan, install, operate and maintain a N2-X Ethernet Extender wireless communicationsystem.The N2-X Ethernet Extender is intended for professional installation only. This manual,however, is also designed for personnel who plan, operate and administrate the N2-X EthernetExtender communication system. Please review the entire manual before powering up ordeploying any N2-X Ethernet Extender.Updates to this manual will be posted on the Wireless, Inc. Customer Service Website athttp://www.wire-less-inc.com. Registered Wireless customers can access Wireless’ on-lineinformation and support service, available 24 hours a day, 7 days a week. Our on-line serviceprovides users with a wealth of up-to-date information, with documents being added or updatedeach month.Radiation WarningsMicrowave Radio Radiation WarningUnder normal operating conditions, N2-X Ethernet Extender radio equipment complies with thelimits for human exposure to radio frequency (RF) fields adopted by the Federal Communica-tions Commission (FCC). All Wireless, Inc. microwave radio equipment is designed so thatunder normal working conditions, microwave radiation directly from the radio is negligible whencompared with the permissible limit of continuous daily exposure recommended in the UnitedStates by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure toRadio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.Microwave signal levels that give rise to hazardous radiation levels can exist within transmitterpower amplifiers, associated RF multiplexers, and antenna systems.Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation.Do not disconnect RF coaxial connectors, open microwave units, or break down anymicrowave screening while the radio equipment is operating.
viiiN2-X Ethernet Extender Installation and Operation ManualMicrowave Antenna Radiation WarningDesigned for point-to-point operation, an N2-X Ethernet Extender microwave radio system willuse directional antennas to transmit and receive microwave signals. These directional anten-nas are usually circular or rectangular in shape, are generally located outdoors, and are usuallymounted on a tower or mast.Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal CommunicationCommission’s Office of Engineering & Technology, limits for maximum permissible exposure(MPE) to microwave signals have been adopted by the FCC for both Occupational/Controlledenvironments and General Population/Uncontrolled environments. These limits are 5.0 mW/cm2 and 1.0 mW/cm2, respectively, with averaging times of six-minutes and thirty-minutes,respectively.The closer you are to the front center-point of a microwave antenna, the greater the powerdensity of its transmitted microwave signal. Unless you are very close, however, microwaveexposure levels will fall far below the MPE limits. To determine how close to a microwaveantenna you can be and still remain below the MPE limits noted above, “worst case” predictionsof the field strength and power density levels in the vicinity of an N2-X Ethernet Extender™microwave antenna can be made from the following calculations. The equation is generallyaccurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e.close to the antenna).S = PG/4πR2where: S = power density (in mW/cm2)P = power input to the antenna (mW)G = power gain of the antenna in the direction of interest relative to an isotropicradiatorR = distance to the center of radiation of the antenna (cm)Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and mustbe converted using the following equation:G = 10 dB/10For example, a logarithmic power gain of 24 dB is equal to a numeric gain of 251.19.Assuming (1) maximum output power from the N2-X Ethernet Extender (+3.5 dBm [2.238 mW]),(2) no signal loss in the cable connecting the N2-X Ethernet Extender to the antenna, and (3)the use of a 27 dBi gain parabolic antenna, the 5.0 mW/cm2 and 1.0 mW/cm2 MPE power densitylimits would be reached at distances of approximately 4.22 cm and 9.44 cm, respectively.Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnelmaintain appropriate distances from the front of all directional microwave antennas. Should youhave questions about N2-X Ethernet Extender™ microwave signal radiation, please contact theWireless, Inc. Customer Service Department.

2N2-X Ethernet Extender Installation and Operation ManualTable 1.1 - FCC U-NII Bands1.3 Regulatory InformationIn January 1997, the FCC made available 300 MHz of spectrum for Unlicensed NationalInformation Infrastructure (U-NII) devices. The FCC believes that the creation of the U-NII bandwill stimulate the development of new unlicensed digital products which will provide efficient andless expensive solutions for local access applications.The U-NII band is divided into three sub bands at 5.15 - 5.25, 5.25 - 5.35 and 5.725 - 5.825 GHz.The first band is strictly allocated for indoor use and is consistent with the European HighPerformance Local Area Network (HIPERLAN). The second and third bands are intended forhigh speed digital local access products for “campus” and “short haul” microwave applications.1dnaB2dnaB3dnaBycneuqerF zHG52.5ot51.5zHG53.5ot52.5zHG528.5ot527.5)xaM(rewoP PRIEsttawillim002PRIEttaw1)PRIE(sttaw4*esUdednetnI ylnOesUroodnIsupmaCselim01xorppAnodesiver)00M(redrodnanoinipomudnaromemCCFtnecerA:etoN* dnaniagiBd32htiwannetnalanoitceridafoesuehtswolla8991,42enuJ IIN-U528.5-527.5ehtnittaw1forewoptuptuorettimsnartmumixama .dnab109530LW

Each radio is shipped from the factory with a standard 6’ coaxial cable forconnection between the radio and the antenna. The cable has a nominal loss of approximately2.6 dB.UNII radios are covered under CFR 47 FCC part 15, 15.407 Subpart E. 15.407.a.2 which statesPtransmit = 11 dBm + 10 log B where B is the -26 dB BW with a 6 dBi antenna. Above 6 dBiantenna gain there is a 1:1 reduction in Ptransmit to maintain the same Maximum EIRP. Thisis accomplished by the changes in output power setting for the alternative antennas.The FCC EIRP limit for the 5.3 GHz band with our transmitter bandwidth is +28 dBm.

Above 6 dBiantenna gain there is a 1:1 reduction in Ptransmit to maintain the same Maximum EIRP. Thisis accomplished by the changes in output power setting for the alternative antennas.The original FCC EIRP limit for the 5.7 GHz band with our transmitter bandwidth is +33 dBm.With the transmit power set to +12 dBm, the EIRP with the 6” Flat Panel antenna, and standard6’ coaxial cable will be:12 dBm + 17.5 dBi - 2.6 dB = 26.9 dBmThe corresponding settings are included in Table 2.5.Table 2.5 - Maximum Transmit Power Level Setting vs. Antenna Type (for compliance with FCC EIRPlimits) in the 5.7 GHz Band, Original and July 31, 1998 rulesepyTannetnAN/PrerutcafunaM timsnarTmumixaM )mBd(gnitteSrewoPiBd1.82,deziraloPenalP,emodarhtiwhsidretemaid'2 IRA25-2PSSleirbaG0iBd1.82,deziraloPlauD,emodarhtiwhsidretemaid'2 IRA25-2DSSleirbaG0iBd5.71,deziraloPenalP,lenaPtalF"6 25-5.DPFDleirbaG21+iBd32,deziraloPenalP,lenaPtalF"21 25-1DPFDleirbaG8+iBd5.72,deziraloPenalP,lenaPtalF"42 25-2DPFDleirbaG4+229102LWThe FCC will also allow higher EIRP for point to point links with higher gain antennas. Page 703of the FCC document, CFR 47 FCC part 15, 15.407 Subpart E, FR 40836, July 31, 1998 hasthe provisions for these power limits. The path length is not increased, since the 5.3 GHztransmitter is not allowed the higher EIRP. We recommend the higher power settings onlywhen absolutely necessary.This rule states “fixed pt-pt U-NII devices operating in this band may employ transmittingantennas with directional gain up to 23 dBi without the corresponding reduction in transmitterpeak output power or peak power spectral density.” Also above 23 dBi antenna gain there is a1:1 reduction in Pout to maintain the same Max EIRP.We are in compliance even at the maximum antenna gain and transmitter power, since thecorresponding output power is over +27 dBm in our BW and the resulting EIRP for a 6 dBiantenna is +33 dBm. This EIRP limit is further extended to +44 dBm by a +23 dBi antenna. OurEIRP with a 23 dBi antenna at maximum output power is 12 dBm + 23 dBi - 2.6 dB = +32.4 dBm.With the highest gain antenna and maximum output power the EIRP would be 12 dBm + 28.1dBi - 2.6 dB = +37.5 dBm.

The RSSI portis used for antenna alignment during installation and for periodic measurement of Receiver/Path performance. The RSSI voltage in proportion to the receive signal level ranges from -30dBm to -90 dBm.2.5 Theory of OperationGeneral OverviewThe N2-X is a point to point Wireless Ethernet Extension operating in the 5.3/5.7 GHz UNII bandas authorized in rule sections 15.401 through 15.407. The unit is enclosed in a weather proofoutdoor enclosure and is intended to provide data links over distances up to 10 km. The radioin the unit operates full duplex, transmitting and receiving data at the rate of 8.192 Mbps. Theradio is modulated using BPSK.Circuit DescriptionThe following circuit description is intended to explain the operation of the radio at the blockdiagram level. This text is written with the idea that the reader has the block diagram readilyavailable, as it will aid in understanding the signal flow in the radio.2.5.1 N2-X Ethernet Extender TransmitterThe input to the radio consists of 10 Mbps Ethernet packets that are routed to the Ethernetbridge chip. The bridge chip stores the data packets, and then converts them into a synchronous8.192 Mbps data stream that is fed into the transmitter.The data is differentially encoded and scrambled before it is routed through the transmitbaseband filter to provide spectral shaping. The baseband filter is a five pole low pass filter. Afteramplification, the baseband signal is fed to the modulator consisting of a doubly balanced mixer.The modulator is running directly at the transmitter frequency of 5.775 GHz ± 50 MHz. The localoscillator signal of the mixer is supplied from the frequency synthesizer section, with thefrequency dependant on the RF channel selected. Operation of the frequency synthesizer willbe detailed later in this document.From the output of the modulator, the signal is amplified and then passed through a 150 MHzwide bandpass filter to remove any local oscillator products from the output spectrum. Afterfiltering, the signal is passed through a series of amplifier and attenuator stages that are usedto control the output power level. With a combination of fixed and variable attenuation the outputpower can be set to one of four different levels to accommodate different antennas used withthe product.The power setting is maintained by an active ALC circuit that samples the transmitter outputpower and then adjusts the variable attenuator to keep the output power constant over theoperating temperature of the unit. The power level is controlled to within +1/-2 dB of the set point.Following the attenuators the signal is fed through additional amplification to bring the outputlevel to a maximum of +14 dBm at the output of power amplifier. A lowpass matching sectionfollows the power amplifier to aid in filtering harmonics of the signal. After passing through theduplexer, the power level at the antenna port is a maximum of +12 dBm.
16N2-X Ethernet Extender Installation and Operation Manual2.5.2 N2-X Ethernet Extender ReceiverThe receiver in the N2-X is a conventional dual conversion design with IF frequencies of 474.88MHz and 70 MHz.From the receive port of the duplexer, the low level input signal is passed through a low noisepreamplifier that provides 25 dB of gain. Following the preamplifier the signal is passed througha 200 MHz wide bandpass filter to provide image rejection for the first mixer.The signal is then mixed with the first LO to convert the signal to 474.88 MHz. Following furtheramplification the signal is passed through a five pole, 20 MHz wide bandpass filter. This filterprovides image filtering for the second mixer, and also helps attenuate signals on the adjacentreceive channels. After filtering, the signal is further amplified and then passed through avariable attenuator stage before it is applied to the second mixer.The output of the second mixer is at 70 MHz. The 70 MHz IF stages provide additional gain alongwith two sections of variable attenuation for the AGC function. The primary adjacent channelfiltering is also at 70 MHz where the signal is passed through a 12 MHz wide SAW filter. Thecombination of filters provide a minimum of 47 dB of attenuation at the adjacent receivechannels (±10.24 MHz).At the end of the 70 MHz IF chain the signal is fed into a quadrature demodulator. The carrierrecovery loop consists of a four quadrant multiplier that multiplies I and Q baseband signals tocreate an error voltage. This error voltage is then amplified and fed back to the 70 MHz VCO.This forms a phase locked loop that is locked to the received carrier frequency.The 70 MHz output is also fed into a wide band logarithmic amplifier that provides a DC voltageoutput proportional to the 70 MHz signal strength. The DC voltage is then integrated and fedback to the variable attenuator stages to form an AGC control loop. This control loop keeps thesignal level at the input to the demodulator chip constant over the entire operating range of thereceiver.Data recovery from the I baseband signal begins by passing the I signal through a slicer. Theoutput of the slicer is a digital signal that contains both data and clocking information. A clockrecovery circuit recovers receive timing information that is needed to clock the data through thedescrambler, and differential decoder.The recovered data stream is then formatted into Ethernet packets and sent out the 10 base-T Ethernet connector.
17N2-X Ethernet Extender Installation and Operation Manual2.5.3 SynthesizerThe FPGA provides four 22-bit streams in a serial format loaded to the synthesizer. This dataprovides all of the possible frequencies at which the system can operate. Depending upon thedip switch settings selected, the actual frequency being used is selected. When the reset buttonis pressed, the FPGA will reload this data to the synthesizer.Frequency SynthesisThe local oscillator frequencies used in the N2-X are all synthesized from a 19.2 MHz, ± 2.5PPM reference oscillator. The overall frequency stability of the radio is ± 2.5 PPM, directlyreflecting the reference oscillator stability.A dual frequency synthesizer chip is used to control both the first and second local oscillatorloops. This chip supports one high frequency oscillator, up to 1.5 GHz, and one lower frequencyoscillator to be used as a second LO.The first local oscillator VCO operates at one half the transmitter output frequency, and changeswith the transmit channel selected. The first LO consists of a bipolar VCO operating at 2.887GHz ±25 MHz. The output of this VCO is buffered and then passed through a X2 prescaler chipbefore being fed back to the synthesizer chip. The phase comparison frequency for the first LOis 320 kHz.After amplification the 2.887 GHz signal is passed through a frequency doubler to create the5.775 GHz signal that is applied to the mixer stages.The second local oscillator consists of a VCO that is phase locked to 404.88 MHz. This auxiliarysynthesizer is operating with a phase comparison frequency of 240 kHz.

21N2-X Ethernet Extender Installation and Operation Manual3.0 Equipment Installation and Commissioning3.1 InstallationThe N2-X Ethernet Extender has been specifically designed for ease of installation. Thefollowing installation instructions should be followed.1. Plan the installation - Decide where each component of the N2-X Ethernet Extender willbe placed prior to commencement of any installation activity. Installation considerations foreach component in general are as follows:a. Outdoor RF Unit - Mount as close as practical to the Antenna assembly. The maximumdistance is determined by the included interconnect cable which is 2 meters maximumin length. Determine pole mounting details for the Outdoor Unit and Antenna.Table 3.1 identifies the maximum transmit power level setting that can be used with eachantenna while maintaining compliance with FCC EIRP regulations. Power levels arereferenced to the antenna port of the radio and are average power levels indicating whatwould be measured using an average power meter. The FCC expresses limits as peakpower numbers. To convert from the average power numbers to peak power numbers,add 1.8 dB to the average power numbers.If the product is being deployed in a country not governed by FCC regulations, theinstaller should select a transmit power level setting appropriate for the antenna that isdeployed to maintain compliance with regulations employed by that country.Refer to Table 2.6 for Configuration Switch setting information.b. Antenna Unit - See Appendix B.

It is extremely important to verify that both antennasare configured for the same polarization, and that the appropriate antenna polarization hasbeen selected for the specific radio link.Table 3.4 - Installation ChecklisttsilkcehCnoitallatsnI?eruceserawdrahgnitnuomkcarehtsI?dednuorgylreporptinuehtsI?detcennocylreporpannetnaehtsI?tcerrocdnaecalpnisnoitcennocatadehterA519530LW
34N2-X Ethernet Extender Installation and Operation Manual3.5.2 Aligning the N2-X Ethernet Extender System AntennasWith the N2-X Ethernet Extender at each site properly configured for operation, antennaalignment must be performed at both sites. Proper antenna alignment is crucial to the properoperation of an N2-X Ethernet Extender radio system, and should only be accomplished byexperienced professionals.The N2-X Ethernet Extender is equipped with a ODU mounted BNC-(f) RSSI connector to whichan analog or digital voltmeter can be connected. The voltage range at the test point, betweenthe center conductor of the connector and ground, varies from approximately two VDC to fourVDC, serving as a receive signal strength indicator (RSSI). The stronger the receive signal, thehigher the RSSI voltage. Refer to Table 3.5.Emanating from a microwave antenna is a main beam (or lobe) of RF energy, surrounded byRF side lobes. The beamwidth of the main beam varies with the size and type of antenna, aswell as the specific frequency of the RF signal, and is generally defined by the nominal total widthof the main beam at the half-power (-3 dB) points. Side lobes surround the main beam at specificangle distances, and will be lower in power than the main beam.When aligning an antenna system, it is extremely important to verify that the antennas are bothaligned on the main beam, not on a side lobe. Referencing Table 3.6, the first side lobe willgenerally be located at an angle slightly less than twice the antenna beamwidth.Following the course alignment of an antenna system, a common practice when performing afine alignment is to slowly swing each antenna (one at a time!) in both vertical (elevation) andhorizontal (azimuth) planes to verify that the main beam and first side lobe can be accuratelyidentified. This insures that accurate alignment of the antenna system on the main beam hasbeen accomplished.Each N2-X Ethernet Extender is shipped with an RSSI test sheet, showing the relationshipbetween the receive signal strength level (in dBm) and the RSSI level (in VDC). These RSSItest sheets are often referred to as AGC Curves. The RSSI test sheets can be used to verifythat the calculated receive signal levels match up with the actual receive signal levels.Substantial differences between calculated and actual levels could point to transmissionsystem problems, side lobe alignment, path obstructions, etc.Table 3.5 - RSSI vs. Receive Signal Level)mBd(leveLlangiSevieceR03-04-05-06-07-08-09-)CDV(ISSR54.407.300.353.206.101.158.0329102LW

Variations in the RSSI voltage could be an indicator ofantenna or antenna feed movement, loose or improper RF cabling or connectorization, pathobstructions or reflections, etc.
38N2-X Ethernet Extender Installation and Operation Manual4.2 Identifying and Resolving Receive Signal Strength IssuesThere are a great number of items which can affect the transmission of a microwave signal fromone site to another. Every microwave path is unique, and must be evaluated for performancebefore a radio link is installed.Outside of radio equipment issues, antenna alignment, RF signal blockage, and multipathfading are among the most common transmission problems experienced in the field.4.2.1 N2-X Ethernet Extender Equipment IssuesFrequency Selection1. Verify the transmit/receive frequency selection for each N2-X Ethernet Extender radio isset appropriately, and that a “matched pair” of radios has been selected for the system.Each N2-X Ethernet Extender terminal can be set to the frequencies listed in Table 4.1.2. To reduce the possibility of co -adjacent channel interference, proper frequency coordi-nation and antenna polarization is used to isolate each channel. The concept is to achievemaximum RF isolation between link channels by means of frequency spacing and antennapolarization. In a “star” configuration an optimum frequency and antenna polarization planis provided to demonstrate an example of maximum isolation between links (See Figure4.1).Figure 4.1 - Frequency Selection for the N2-X Ethernet Extender Radio1H 12H24H43H37V78V86V65V5H = Horizontal Antenna PolarizationV = Vertical Antenna PolarizationWL035917HHHHVVVV

A-1N2-X Ethernet Extender Installation and Operation ManualAppendix A Grounding Practices and LightningProtection InformationGeneralGood grounding (“earthing”) practices, when used in telecommunications, have some directbenefits which can help you maximize the up time of your system as well as ensure the safetyof those people working on the system. Among these benefits are:1. Protection of personnel from electric shock and fire hazards.2. Reduction of radiated and conducted electromagnetic susceptibility.3. Improved system tolerance to discharge of electrostatic energy and lightning interference.4. Minimized service interruptions and service damage.There is no practice or formula which can completely eliminate the above risks, but we atWireless, Inc. believe that good grounding and bonding practices can significantly reduce therisk of many of these hazards. We have included a bibliography at the end of this appendix whichcontains several publications that are readily available and contain detailed information onmany aspects of grounding systems and their design, implementation, measurement, andmaintenance.Please note that every telecommunication site is unique, and must be evaluated accordingly.The following information is provided for generic reference and educational purposes only. Thegrounding plans and practices for a given site should only be established and accomplished bytrained professionals, working in accordance with local practices and regulations.Ground ConnectionsThere should be a grounding plan designed at the outset of site design in order to provide thebest grounding procedures and to minimize ground loop currents. This should be achieved byconnecting the outer conductors of the cables through a large section copper strap to a centralgrounding point and the size of the conductor should be increased as each branch path isadded. The final conductor should be connected directly to the grounding system. For a radiosite a single copper grounding rod is insufficient because its impedance is likely to be too high.Lightning ProtectionRadio sites can be particularly prone to lightning strikes by virtue of their normally exposedlocations and the presence of relatively tall antenna support structures.It is not possible to provide and guarantee complete protection from the effects of lightning;however, they can be significantly reduced by careful attention to grounding, protectiondevices, and the layout of the site itself.Reference should also be made to various publications, some of which are listed in theBibliography. Where any site owner or user is in doubt about the protection requirements for anyparticular location, the appropriate authority should be consulted.
A-2N2-X Ethernet Extender Installation and Operation ManualProtection ArrangementsThe purpose of any protection arrangement should be to provide a suitable path to ground forthe lightning current, to ensure adequate bonding between structures and all metalwork on thesite and the common grounding system in order to reduce the side flashing, and to attempt toprevent the entry of flashes or surges into the building.The resistance to ground should be kept to a minimum and a value of less than 10-ohms isrecommended. The most important feature is that the system should ideally be at equalpotential across the entire site.Certain authorities and service providers have their own particular practices which have to befollowed where applicable.Arrangements will vary considerably from very simple sites to complicated sites with multiplebuildings, antenna support structures and associated equipment, and may involve integrationwith existing systems. Such systems may require upgrading.Lightning conductorsDown conductors, bonding interconnections, ground rings and radial tapes should be ofuninsulated 000 AWG copper cable or solid copper tape with a minimum cross section of 25 x3 mm with all connections protected by non reactive paste.Protected test points should be included if appropriate, and sacrificial ground lugs should beclearly marked and easily accessible for periodic inspection.Grounding of antenna support structuresA structure will generally act as its own lightning conductor and therefore will not require anadditional conductor from the top to the base. A lightning rod may be required to extend the zoneof protection to protect equipment mounted on the top of the structure. The lightning rod shouldextend 2.5-meters above the highest equipment.Ground mounted support structures should be connected at their base to a ground ring viasacrificial ground lugs. Towers should have a connection from each leg.A ground ring should consist of copper cable or solid copper tape with ground rods equallyspaced at 2-meter intervals around the base of the structure as close to it as possible, buriedapproximately 0.6-meters deep where soil conditions allow. An alternative method using radialsrather than rings is detailed in “The ‘Grounds’ for Lightning and EMP Protection”, secondedition, published by PolyPhaser Corporation.The ground ring should be connected to the main building ground by the most direct route,buried as appropriate.Roof mounted structures should be connected to the main building ground by the most directroute using sacrificial lugs and copper cable or tape as appropriate. Tower guy wires should bedirectly bonded at their lowest point to a suitable ground electrode or connected to the siteground by the most direct route.
A-3N2-X Ethernet Extender Installation and Operation ManualGrounding of feedersAll antenna feeders should be bonded to the tower at the upper and lower ends and groundedat the point of entry into the building. Weatherproof grounding kits are available from antennamanufacturers.Note: Many of the cables used by Wireless, Inc. have braided rather than solid outerconductors; this type of grounding is not appropriate. In these cases we recommend theuse of Wireless, Inc. approved lightning arrestors. For information on lightning arrestors,please contact Wireless, Inc.’s Customer Service department.Grounding of buildingsA ground ring ideally should surround the building and be connected to individual groundsassociated with feeder entry, antenna support structure, building lightning conductor, equip-ment room, main AC supply and other facilities. Each connection should be made by the mostdirect route in order to minimize interaction between the different grounding functions.The ground ring should consist of copper cable or tape with electrodes 2- meters or greater inlength, buried to a depth of 0.6-meters and at a distance from the building not to exceed 1-meter.Buildings may require lightning rods where they are not within the zone of another protectedstructure.BIBLIOGRAPHYITU - T K.40 Protection against LEMP in telecommunications centresITU - T K.27 Bonding configurations and earthing inside a telecommuni-cation buildingITU - T K.35 Bonding configurations and earthing at remote electronicsitesITU - T K.39 Risk assessment of damages to telecommunications sitesdue to lightning dischargesITU - T Lightning Handbook The protection of telecommunication lines and equipmentagainst lightning dischargesIEEE Emerald Book - Powering and GroundingThe “Grounds” for Lightning and EMP Protection, second editionPublished by PolyPhaser Corporation

Do not hoist by the elevation rod. Make sure that the vertical assembly isunobstructed where it will mount against the mast pipe.2. Attach tag lines and carefully lift the antenna into position, resting the vertical assembly onthe shear stop clamp.3. Fasten the mount to the mast pipe with 1/2” U-bolts. The antenna must be free to rotateduring azimuth adjustment, so tighten only enough to close the gap between the mast andvertical channel. Do not leave the antenna loose for any extended period of time, i.e.overnight.Figure B.17 - Hoisting the AntennaWL0359485”(127mm)
B-16N2-X Ethernet Extender Installation and Operation ManualGeneral Antenna Alignment ProceduresNormally the antenna is aligned by performing azimuth and elevation adjustments andelevation adjustments as necessary until the peak signal is obtained. It may be helpful to re-peak one adjustment before finalizing or locking down the other.Warning: Damage to the antenna can occur if azimuth or elevation adjustments areattempted without loosening the proper connections as described in the following steps.Azimuth Adjustment1. Be sure the mast pipe U-bolts are just loose enough to allow mount rotation whilemaintaining complete contact between the mount and the mast pipe.2. Turn the long stainless steel azimuth screws against the mounting channel. By alternatelyturning one azimuth adjustment screw out and the other in, the antenna can be rotated tothe desired azimuth angle. Approximately 1 turn changes the azimuth direction by 1°. Avoidadjusting the antenna beyond the ±5° provided by the azimuth clamp as this can damagethe adjusting hardware. Fasten the antenna to the mast pipe and reposition the clamp ifneeded.Note: By securing the mount to the mast pipe and realigning the azimuth clamp with theantenna boresight, more reliable and precise azimuth adjustments can be achieved.After all adjustments are made, tighten both of the azimuth screws against the channel andsecure with the lock nuts provided.3. Tighten the mast pipe U-bolts while maintaining the peak signal by alternating from left toright in 1/4 turn intervals.Elevation Adjustment1. Insure that both of the bolts connecting the mount to the Top Support Angles and thepivoting Elevation Angle (refer to Figures B.7 and B.9) are just loose enough to allowresisted rotation.2. Back the outer nuts on the elevation rod away from the bottom mount plate to allow somefine adjustment range.3. Turn the inside nut (with flat washer) on the elevation rod to adjust the elevation angle.Approximately 5 turns changes the elevation by 1°. Remember, for elevation greater than20°, install the two beveled washers as shown in Figure B.9.4. After all adjustments are made, lock the nut against the bottom mount plate. Tighten theangle pivot bolt and support bracket bolts.Important: Be sure to tighten all hardware after final adjustments and insure that splitlockwashers, palnuts, or jam nuts are used where provided.
B-17N2-X Ethernet Extender Installation and Operation ManualTable B.3 - Nut Tightening ProceduresInspection and Maintenance1. Before leaving the installation, check that all hardware on the mount, shroud, radome, andfeed is tight and that nuts are locked in place.2. Inspection of the antenna should be performed at lease once a year to check its conditionand to insure safe operation and maintenance. Qualified personnel, knowledgeable andexperienced in antenna installations, are required for this inspection.Supplemental InformationTable B.3 is provided for installers unfamiliar with adequate nut tightening procedures for useon stainless steel bolts, U-bolts, galvanized bolts or any bolts without the ASTM-”A325” markingon the head. Disregard these recommendations when specific tightening requirements aregiven.Note: It is not recommended to reuse a palnut that has already been fully tightened ordeformed in any way. It should be replaced by a new palnut.Weather Proofing the Type N Female Connector on FeedsRemove the protective cover from the end of the feed and mate the connectors, screwing themale connector firmly onto the feed.Important: After connecting the coaxial cable, wrap the Type N connector with the gray butylrubber, squeezing it firmly around all joints to make a continuous seal. Finish theweatherproofing by wrapping the butyl rubber with several layers of black PVC tape (notsupplied).eziStloBlanimoNeuqroTtuNeuqroTtunkcoLtunlaP"4/1.bl/.ni05.bl/.ni04"61/5.bl/.ni201.bl/.ni06"8/3.bl/.tf51.bl/.ni58"61/7.bl/.tf42.bl/.tf51"2/1.bl/.tf73.bl/.tf61"8/5.bl/.tf47.bl/.tf82"4/3.bl/.tf571.bl/.tf44"8/7.bl/.tf212.bl/.tf15"1.bl/.tf813.bl/.tf95059530LW
