CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-1 EST P/N AA107G ANTENNA AND CABLE CONFIGURATIONS (POLE MOUNT) EST offers different types of antennas for both indoor and outdoor configurations. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. Warning: Only the tested cable lengths and antennas provided by EST meet the FCC maximum peak output power requirements. Any other combination of antennas or coax cables is not authorized. This device has been designed to operate in a pole mount configuration with the antennas listed below, and having a maximum gain of 6 dB in a multi-point system or 19dB in a point to point network. Antennas not included in this list or having a gain greater 6 dB in a multi-point system or 19dB in a point to point network are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.

Antenna Port B is a receive only port and is used for dual diversity antennas applications only. This port is not used for point to point applications. Warnings: Only pre-made coax cables from the factory used in conjunction with either the AA20Eg omni-directional and AA203Eg or AA204Eg directional antennas meet all FCC Section 15.247(b) EIRP maximum power requirements. Use of the AA204Eg, directional antenna is limited to fixed point to point applications only. In accordance FCC Section 15.247(b)iii, this antenna must be professionally installed. The installer must ensure the system is used exclusively for fixed, point-to-point applications and the ESTeem Model 195Eg is set for 0.25 Watts output power (Power Level = Min).
CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-2 EST P/N AA107G ANTENNA AND CABLE CONFIGURATIONS (CABINET MOUNT) Warning: Only the tested cable lengths and antennas provided by EST meet the FCC maximum peak output power requirements. Any other combination of antennas or coax cables is not authorized. This device has been designed to operate in a cabinet mount configuration with the antennas listed below, and having a maximum gain of 7 dB in a multi-point system or 11dB in a point to point network with the authorized ESTeem coax cables. Antennas not included in this list or having a gain greater 7 dB in a multi-point system or 11dB in a point to point network with any other types or lengths of coax cable are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. Part Number: AA20E •••• Omni Directional Building Mount Antenna, 6 dBd gain •••• Feedline minimums: 25 ft. RG-8 Cable or 50 ft.

COAXIAL CABLES A 25-ft. length of RG-8 coax cable or 50-ft. length of ½”Heliax cable are the minimum cable lengths allowed for use with the above antennas (AA20E, AA203ES, AA204ES) when the Model 195Eg is set at Max Power. Listed below are representative cable losses in db/100 ft at the 2.4 GHz frequency range: Feedline Type Attenuation (dB/100 ft.) @ 2.4 GHz Additional RF Losses Attenuation (dB) RG-8 (Solid) 7 AA228LMR (2.5’ TNC-MRP/N-MRP) Jumper Cable 0.9 LMR 600 4.4 AA165 Lightning Arrestor 0.1 3/8" Heliax 6.5 All Coax Connector Terminations (2 for every coax cable) 0.2 1/2" Heliax 3.5 7/8" Heliax 2 1.25" Heliax 1.6 In a severe noise environment it may be necessary to use a double shield type of coax cable such as RG-214/U in place of the RG-8. This cable must be purchased from the factory to meet FCC requirements. Warning: Only pre-made coax cable systems (Cable, Lightning Arrestor and AA228LMR jumper cable) from the factory used in conjunction with either the AA20E omni-directional and AA203ES or AA204ES directional antennas meet all FCC Section 15.247(b) EIRP maximum power requirements. Use of the AA204ES, directional antenna is limited to fixed point to point applications only. In accordance FCC Section 15.247(b)iii, the operator or installer is responsible for ensuring the systems is used exclusively for fixed, point-to-point applications.
CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-3 EST P/N AA107G Note: A -3 dB loss means you have lost 1/2 of your signal or transmitter power. A +3 dB gain means you have doubled (x2) your signal or transmitter power. Example: A 6 dB antenna will increase the radiated output power of a 1 watt transmitter to 4 watts {times 4 = 3 dB (x2) + 3 dB (x2)} and increase the received signal strength to receiver times 4. WEATHER PROOFING COAX CONNECTIONS 1. Coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Care should be taken not to get any lubricant on the center conductor. 2. Wrap the connector assembly with a vapor barrier patch for weather proofing (See Note 2), ensuring to overlap onto the coax cable approximately 1 1/2 inches. 3. Apply an electrical coating (sealing agent) over the vapor barrier patch for added protection (See Note 3). Notes: 1. Dow Corning RTV-3140 or equivalent. 2.

CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-4 EST P/N AA107G ANTENNA DIVERSITY The dual diversity antenna configuration on the ESTeem Model 195Eg allows the radio to operate more efficiently in areas with high reflections (such as indoors or in a city) and without direct line of sight (LOS) between the antennas. One of the most difficult conditions to control in a radio system is the effect of a destructive reflected radio signal called mutipathing. Multipathing occurs when waves emitted by the transmitter travel along a different path and interfere destructively with waves traveling on a direct line-of-site path. The phenomenon occurs because waves traveling along different paths may be completely out of phase when they reach the antenna, thereby canceling each other out. The dual diversity antenna configuration places a physical distance between the antennas where one reflected signal will be out of phase, but the second will be not. The ESTeem Model 195Eg will sample both antennas and select the best receive signal. ANTENNA PORT SELECTION The antenna ports on the Model 195Eg must be configured for either a single receive antenna (external mount antennas) or dual diversity antenna setup. To access the port configuration open ESTeem Web page using your computer’s Web Browser as per instructions in Chapter 4. Select Advanced from the menu items and Radio Settings-wlan0 device (Figure 1). Figure 1: Advanced Settings Menu
CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-5 EST P/N AA107G Press the next button and Figure 2 will be displayed. The receive antenna is configured by selecting the wlan0_dot11CurrentRXAntenna drop down (Figure 2) and selecting the receive antenna. A value of 0 = Dual diversity (Both antenna Ports A & B will be used to receive). A value of 1 = Single receive source (Antenna Port A only). Figure 2: Receive Antenna Settings Menu
CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-6 EST P/N AA107G ASSEMBLING THE AA195PM TWO HOLE OUTDOOR POLE MOUNTING KIT The AA195PM mounting kit contains everything required for pole mounting and weatherproofing the ESTeem Model 195Eg for outdoor installations. The 195Eg with AA195PM mounting kit can be directly mounted to a round pole from 1.25” to a diameter of 2.25” OD. Any mounting structure greater than 2” requires hose clamp strapping run through the Pole Mount Brackets. The mounting kit requires the following assembly: 1. If you purchased an AA195PM mounting kit with your Model 195Eg, the kit will be packed in the same packing box as the ESTeem (Figure 1). 2. Remove and inventory the two (2) Pole Mounting Brackets, one (1) Two-Hole Face Plate Cover (with single port cover installed), one (1) Heat Shield and (1) AA195PM Hardware bag from the packing box (Figure 1). Report any missing or damaged items to ESTeem Customer Support (509-735-9092 Phone) as soon as possible for replacement.

CHAPTER 8 ANTENNA SETUPS Revised: 2 Jul 08 8-16 EST P/N AA107G FRESNEL ZONE The Fresnel zone shows the ellipsoid spread of the radio waves around the visual line-of-sight after they leave the antenna (see figure above). This area must be clear of obstructions or the signal strength will be reduced due to signal blockage. Typically, 20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage, signal loss will become significant. This calculation is based on a flat earth. It does not take into account the curvature of the earth. It is recommended for RF path links greater than 7 miles to have a microwave path analysis done that takes the curvature of the earth and the topography of the terrain into account. Fresnel Zone Radius = 72.1 SQRT [(d1d2) / (F(d1 + d2)] Units Fresnel Zone Radius in feet. d1 and d2 in statue miles F in GHz
