The main transmitter is connected to the antenna, while the standby transmitter is connected to dummy load. A failure in the main transmitter will cause an automatic change over to the standby transmitter.The audio signals are generated in the LF circuitry mainly by a Field Programmable Gate Array (FPGA). A strap field selects Inner, Middle or Outer Marker settings.An onboard oscillator generates a 75MHz carrier wave which is amplitude modulated with the LF GENERATORRF OSCILLATORPOWERAMPLIFIERCHANGEOVERLOCALCONTROLTX1/TX2ON/OFF75 MHz400 Hz1.300 Hz3.000 HzKEYBOARDDISPLAYADCPUNM7050 - MARKER BEACONSTATIONCONTROLADCPUMONITORINGMAINTENANCE +RMM INTERFACEMONITOR RFFRONTEND MONITORBASEBAND+RF LEVELOPTIONAL MONITOR 2 REMOTECONTROLSLAVEPANELLOCAL PCREMOTE PCRMMPOWERSUPPLYCONNECTIONINTERFACETRANSMITTER 1 TRANSMITTER 2 MONITOR RFFRONTEND MONITORACDCDCDCLINE+MODEMMONITOR 1 OPTIONAL POWERMO 1374MO 1374TX 1373LC 1377CI 1376PS 1375DUMMYLOADMAINS BATTERY SENSORS ETC.BASEBAND+RF LEVELMAINTENANCE +RMM INTERFACE MONITORINGSTATIONCONTROLSPLITTER ONLY PRESENT IF TWO MONITORSLF GENERATORRF OSCILLATORPOWERAMPLIFIER75 MHz400 Hz1.300 Hz3.000 HzTX 1373ON/OFFMODULATION DEPTHOUTPUT RF LEVELKEYING NORMAL/OFF/CONT.STATUS+20V+/-15V+5VMONITOR 2DATALINE+MODEMHBK782/1RMM

The PA is capable of delivering up to 4W power at 97% depth of modulation.Unwanted frequencies are removed by a lowpass filter after the PA.3.3 Monitors / Transmitter Control The marker beacon has one or two MO1374 monitor modules depending on model (Table 3-1). The MO1374 is mainly a microprocessor based module. It contains the MB software and forms the basis of the monitor, station control, system maintenance handling and RMS user interface.A detection of error in the transmitter signal causes change-over to the standby transmitter. Failure of the standby transmitter leads to an alarm and optional shutdown of the standby transmitter.On a system with two monitor units, both must report error for alarm to be generated (2 of 2 voting). If the monitors disagree, the WARNING and DISAGR LEDs on the front panel is lit.The MO1374 consists of two submodules:The RF frontend receives a RF signal from the antenna (or recombining network for dual antenna system). It demodulates the signal into analogue values propotional to the RF power, the modulation depth and the morse code envelope. These parameters are digitized and monitored by the CPU section.The CPU section includes an 80CI88 CPU, memory, communication ports and an AD con-verter system.3.4 Power SystemsThe marker beacon can have either one or two PS1375 power modules depending on model (Table 3-1). The PS1375 is 100W with 120V or 230V AC input voltage and +28V/3.5 A, +20/2.5A, ±12V/1.25A and 5V/6A DC output voltages. Outputs are short circuit protected. On the NM7050 B/D the two modules operate in parallel.The 28V output is temperature compensated to ensure optimum battery charging. It gives 26.4V at 50°C and linearly increase to 29.6V at -30°C.The backup battery is an external 24V battery. The battery gives a backup time of 6 hours, and have external charging possibilities for longer backup time. This battery is automatically brought into circuit on mains power failure. The charging time is approximately eight hours with one PS1375 and five hours with two PS1375.3.5 Remote control systemThe remote control unit is used in the tower or in the technical control room. It has indicators for operating status as well as detailed warnings and an aural alarm device with reset. It can control equipment on/off and change over, and has an Access Grant switch to allow/inhibit remote control from the RMM system.
USER MANUAL3-421464-5NORMARC 7050MARKER BEACONSystem Description ©1999 Navia Aviation ASThe Remote Control Unit is connected to the MB by one pair telephone cable.3.6 Remote Maintenance Monitoring (RMM)The NM7000 series has a built-in Remote Maintenance Monitoring system. This system con-sists of the RMS system, remote PC terminals with the RMM program installed, and the local keyboard/display. Figure 3-2 illustrates the RMM/RMS systems.Figure 3-2 The NM 7050 RMM/RMS systemsThe centre of the RMM system is a CPU with the RMS core program. The RMS collects mea-surements and diagnostic data, and makes them available to the user. The collected informa-tion allows easy and cost effective maintenance, fault finding and routine reporting. In addition, system settings are distributed and parameter readings are collected via the RMS/CPU.External Personal Computers are used for a user friendly interface to the RMM system. The equipment has two serial output ports, typically used to connect a local PC and a connection to a central maintenance facility.RMShardwareRMScoreprogramLocalmeasuringpointsMaintenancedata busRMS data busLocalparameterstoragesLocalKeyboard/DisplayModemNM7050RMS systemRMM systemLocalRemoteRMM programModemprogramRMM HBK783-1
©1999 Navia Aviation AS 21464-5 System DescriptionUSER MANUALNORMARC 7050MARKER BEACON3-5The local keyboard/display allows readings and controls through an LCD display and a seven-button keypad. This gives access to the RMM functionality without the need for a PC.3.7 RMM AccessAccess to the RMM system is controlled by multiple hardware and software access controls. One password is required for each access level, i.e. one password for level 1, two for level 2 and three for level 3. Optional hardware controls may inhibit writing in the upper access lev-els.Access level 1• Readout of all the monitor values, warning and alarm limits.• Readout of all the maintenance values and warning limits.• Readout of all the delays.Access level 2• TX1 and TX2 : morse normal, continuous or off.• TX1 and TX2 : test signals 50% depth of mod. and 50% RF level.• Diagnostics.Access level 3• Settings of all the monitor warning and alarm limits.• Settings of all the maintenance warning limits.• Settings of all the delays.3.8 Storage FunctionsThe RMS has the following storage functions:Alarm Storage:8 alarm logs can be stored. One log consists of a CURRENT LOG and a HALF MIN LOG. Current log is a continuous 2 seconds log of monitoring and maintenance parameters. Half min log is a 30 seconds log of monitoring and maintenance parameters sampled at 5 second intervals. A log is stored when a SHUT-DOWN or CHANGE-OVER alarm occurs.Periodic Storage:Stores 16 data sets of monitored data on configurable periodic intervals. Event Storage:Stores the last 50 events. Each event is stored with a TIME_STAMP and a USER_ID (of the user executing the command). Stored events are; change in WARNING and ALARM states, excution of STATION CONTROL COMMANDS, changes in WARNING and ALARM LIMITS on logout from access level 3, SYSTEM ADMINISTRATION, and log-in and log-out at access level 2 and 3. 3.9 Local Keyboard/Display FunctionsThrough a menu based interface all main commands, adjustments and monitor limits are accessible from the front panel keypad and LCD display. In addition a quick read function gives readout of all main monitor parameters at a glance.

See the Engineering and Commissioning Handbook for further details.5.1 Marker beacon CabinetThe NM7050 cabinet is constructed for mounting on a wall. For easy operation, the keyboard and display section should be in eye/shoulder height (140-160cm). The ventilation holes at the bottom of the cabinet should be kept uncovered to ensure proper cooling.The cabinet is 45 cm wide, 34 cm deep and 27 cm height and weighs about 5 kg.When mounting the cabinet on a wall, do the following:• First drill the holes according to Figure 5-1.• Mount the upper screws. Leave 6 mm distance from the screw head to the wall.• Hang the cabinet on these screws, using the key holes on the mounting rails• Mount the lower screws • Tighten all screwsFigure 5-1 Mounting the cabinet on a wall.5.2 Remote controlThe Remote Controls are normally organised in 19" subracks three units high. Normarc offers such a subrack called RFA 1353 (Remote Control Frame) shown in Figure 5-2. Maximum five Remote Controls and one power supply (like PS 635) fit into RFA 1353 which is 33 cm deep.MARKER BEACONONOFFOFFBATTERYONLOCAL RS232POWERMAINSREMOTELOCALAUTOMANUALWRITEPROTECTMAINTX TO AIR+ON/OFFSTBYMAINTBATTDISAGRPARAMALARMWARNINGOVERCHANGENORMALSERVICE TX1ESC-PREV NEXTREADTX2QUICKENTER405Hex lag screw 6x50Hex lag screw 6x50Washer M6Washer M6340451 mm5HBK 860-1

A 16Ah battery gives approximately six hours backup time with 5-8 hours charging time dependent on model. For longer backup time an external charger is required to be able to charge the battery within a reasonable time. An external battery protection circuit (like Nor-marcs BP 543) has to be connected between the EXT. CHARGER (+) and BATT GND (-) input. In addition MAINS directly on NM 7050 has to be disconnected.

This volt-age is greatly dependent on the temperature. The battery life time will decrease if this rule is not followed. To meet the demand, the internal battery charger(s) in NM 7050, the PS 1375, has a temperature compensated charging voltage.Due to current limiting in PS 1375, a discharged battery will firstly be charged with a constant current, ≈2A with one PS1375 and ≈6A with two PS1375. When the battery draws less than the current limit, the battery will be charged with a constant voltage (UBATT). The factory set-ting for the internal battery charger is:UBATT20 = 27.6V @ 20°C with . This is the normal final voltage for lead acid accumulators. If your batteries require a different final voltage, the adjustment procedure is as follows:• Turn the BATTERY switch OFF and have one TX on .• Measure the environment temperature TENV (in °C)• Compute the temperature deviation ∆T = TENV - 20°C• Compute the new expected final voltage at your environment temperature as • Adjust the potentiometer on PS1375 until you measure UBATT on the 27V test point on CI 1376.ΤInner Marker uses an external 10 dB attenuator, use 0.2W, 0.1W and 50mW tocalibrate. CARRIER POWER is measured prior to the attenuator, but the soft-ware will automatically compensate for the 10dB. Example: Your battery requires a final voltage of 26V at 20°C, and you have measured an envi-ronmental temperature of 25°C. You should then adjust the charger to give UBATT = 26 + (-0.04)(25 - 20) = 25,8 VkUTmVCBATT==°êú∆∆- 40UU kTBATT BATT=+⋅20 ∆

The purpose of the system is to retrieve status and measurements from the MB rack and to change the MB operation and parameters. The retrieved data can be displayed and further processed by programs on the PC. This includes displaying data on screen, saving data and exporting data to other pro-grams, i.e. for trending analysis.10.1.1 System RequirementsAs mentioned above you need a PC to run the RMM software. The operating system has to be either Windows 95 (or newer) or Windows NT 4.0 (or newer). The table below shows the hardware requirements to make the software play well.Table 10-1 PC hardware requirements10.1.2 How to use this manualThe RMM is a windows based software, and uses standard windows interface. If you are familiar with windows you can skip Chapter 10.2. If you are not the type that reads manuals in bed at night (engineers are usually not), the chapter 10.4 Getting started will give you a quick guidance into the system.The chapters 10.4.2 and 10.5.16 are for the System Administrator, normal users may skip these chapters.10.2 The desktop areaThe purpose of this chapter is to give the inexperienced Windows user some quick instruc-tions on the environment.

You may connect to, add, edit or remove entries on the list. This is also the place to set up the modem connec-tions.You may have different types of connections to the same station, i.e. one direct line, one leased line and one dialled line connection. This can be particularly useful on portable PC's that are used both on site, in the control room and more distant places.Figure 10-12 The Station List viewFigure 10-13 The Edit Station view
USER MANUAL10-1621464-5NORMARC 7050MARKER BEACONOperation of RMM ©1999 Navia Aviation ASThe STATION NAME may be chosen freely. The maximum number of characters is unlimited for all practical purposes. Be aware that this name will also be the name of the home directory for this station, where for example the log files will be put as default. We recommend mean-ingful names like MIDDLE MARKER 01, OUTER MARKER 19 LEFT to tell the marker type and run-way end. You may also include the site name if you handle NM7050s on more than one airport.The PHONE NUMBER is only necessary when using modems on the public telephone net (CON-NECTION TYPE = DIALLED). Simply enter the telephone number in the same way that you would dial on your phone.10.5.5 Modem set-upTo change set up for connected modems, select the MODEM INIT button in the Station List View. You will now enter the modem set-up dialogue.Figure 10-14 The Modem Init windowThe Comm. Port part of the dialogue shows the set-ups for the modems connected. Note that these set-ups are based on what kind of modems that are connected to each of the COM ports connected to the PC. There are set-ups for both normal DIAL-UP INIT STRING and LEASED LINE INIT STRING. Theses strings are sent to the modems at the start of a station connection, but only if DIAL-UP or LEASED LINE is selected in the Station List View. When changing the settings, remember to select the SAVE SETTING button before exiting the dialogue (pressing the OK button). These settings are saved for the next time you start up the program.ΤIf your modem connection have to go through a local telephone switchboard, youhave to enter the code to get the public dial tone, to commas to make a pause andfinally the phone number. Ex.: 0,,11223344
©1999 Navia Aviation AS 21464-5 Operation of RMMUSER MANUALNORMARC 7050MARKER BEACON10-17The Set-up part of the dialogue is just a collection of fixed set-ups that can be selected (by using the SETUP NAME combo box), and then copied to the set-up for the selected COM port (by selecting the COPY TO COMM PORT SETUP button). The set-ups can be edited and saved much in the same way as the stations in the Station List View.10.5.6 Setting up connectionsThe Com Port is a physical plug on your PC that transfers serial data communication. They are normally tagged COM1, COM2,.... on the rear of your PC. A standard PC configuration has two COM-ports where the mouse might occupy one of them. Use a free COM port to con-nect your modem or NM7050 directly and select the same port from the list. If you have a modem installed the list will say for instance MODEM ON COM2.There are three CONNECTION TYPES:• Direct Line• Leased Line• Dialled LineDIRECT LINE is typically a serial link cable with a nine pins D-SUB contact in each end. You may use either the Local or the Remote port on NM7050 and one of the COM ports on your PC. The direct line is limited to approximately 15 m cable length.LEASED LINE is a dedicated telephone line where you are the only user. There will be no need of a telephone number, but you need a leased-line type modem in each end to be able to drive the line. There is no length restrictions on a leased line if the telephone line standards are fol-lowed.DIALLED LINE is a normal public telephone line where the signal passes a number of telephone switches on its travel. You need a dial up modem to dial the number and drive the telephone line. As with normal telephones, you may phone all over the world.Figure 10-15 The connection typesMARKER BEACON SYSTEMDial up modemTelephoneswitch TelephoneswitchLeased line modem Leased line modemLeased line (>15m)Dialled line (>15m)Direct line (<15m)H1024-1MARKER BEACON SY STEMMARKER BEACON SYSTEM

The boards and the parameters belonging to the specific board are listed here:TX1373A-1PaCurrent This is the current that is drawn from V20P in the RF Power Amplifier.Pa_V20p This is the measured voltage for the +20V input.RFLevDetect This is the analog RF-level value from the on-board detector on the transmit ter.RFLevelDac This is the DC-voltage controlling the carrier power.CarrierPower This is the calculated carrier power output based on RFLevDetect.ModDepth This is the calculated modulation depth from the on-board detector.VDD This is the measured value for the +5V input power.V12P This is the measured value for the +12V input power.V12N This is the measured value for the -12V input power.Lf1KeyGate This is the signal controlling the keying (modulation on/off) for the transmit ter. The signal will be toggling between '0' and '1' when keying is ON, '0' when keying if OFF and '1' when keying is CONT (continuous).

This will be low when the NM7050 is running on battery power.V20P This is the +20V power from this power supply.VDD This is the +5V power from this power supply.V12P This is the +12V power from this power supply.V12N This is the -12V power from this power supply.I28Vcurrent This is the current measurement for the current that is generated by the mains power.IBattCurrent This is the current that is going in/out of the power supply. Normally this value will be positive when the mains power is charging the battery, and neg ative when the system is operating on battery. However, when there are two power supplies in the NM7050, the power supply with the highest +28V output will actually charge the power converters on the other power supply. This will be indicated by a negative value for this parameters on the other power sup ply. To calculate the actual current that is charging the battery, the IBattCur rent parameters for both power must be added together. For example if the IBattCurrent for the two power supplies shows 1.4A and -0.5A, the actual charge current to the battery is 0.9A.PS1375A-2Same parameters as for PS1375A-1CI1376AV28P The system +28V power, measured on the power line connected with the bat tery.V20P The system +20V power.V12P The system +12V power.VDD The system +5V power.V12N The system -12V power.TInDoor The temperature measured on the TEMP INDOOR connector inside the NM7050 cabinet.

An on board oscillator working at 75 MHz provides an output of app.0 dBm that is used as input to the Power Ampli-fier (PA). The level of this input signal is adjusted to an output of app. +20 dBm. The Power Amplifier is capable of delivering up to 4W carrier power at the cabinet output.Unwanted frequencies are removed by a lowpass filter after the PA. Part of the signal out of the PA is tapped off to be demodulated and used for feedback and self test purposes. Demod-ulation is done by a mixer with a linear detector.The audio signals are generated in the LF circuitry mainly by a Field Programmable Gate Array (FPGA). Inner, Middle or Outer Marker is selected by straps.12.1.1.2 Block diagramFigure 12-1 TX1373 Block diagram12.1.1.3 SignalsOscillatorModulation detectorLP filterPower AmplifierAutomatic Gain ControlRF OUTLF GeneratorMaintenance/MonitorModulation AmpModulation ControlAMUX_A[3:0]DAC_DATA[7:0]DAC_CTRLMODULATION / BIASRF LEVEL / IDENTMAINTENACE SIGNALSDET_SIGNALTXCSTXWRTXRDIOD[7:0]TX_CTRL_BUSTRANSMITTRANSMITRMS_LEV[1:0]A_TX[P,N]HBK817-1

The modulation voltage is 0-12VDC both at stage one and stage two. With an input signal from oscillator / AGC of +20 dBm, the first stage will deliver +30 dBm peak power with a dynamic range of 25 dB. A 10 dB resistive π-attenuator is inserted before stage two. The input to the second stage will then be +20 dBm. After amplification and modulation, the peak power will be +30 dB, but the dynamic range is increased to 50 dB. The last stage is a MRF 171 MOSFET transistor designed to deliver high power output. It is biased by 1mA and +20VDC drain voltage. After amplification, the peak power will be +43 dBm with a dynamic range of 75-80 dB. The TX is capable of delivering 4W carrier power.Signals in: 75 MHz RF from oscillator / AGC.Modulation voltages, up to +12VDC.Power Supply, +20 VDC.Bias, 0-5 V, to power stage.Signals out: RF to detector / LP Filter.LOW PASS FILTERThe output signal from the PA is filtered to remove harmonic frequencies. The filter is a seven pole passive lowpass filter.Signals in: 75 MHz RF PA.Signals out: RF to CI 1376.MODULATION DETECTOR Part of the output signal is demodulated for feedback and self test purposes. The signal is tapped out via a hybrid coupler to avoid destructive coupling from the detector to the output signal and make sure the detected signal is good. The detection is achieved by a mixer and linear detector. The output is used both as feedback to the modulation control circuitry, and sent to the monitoring circuit where RF level and keying envelope are detected.Signals in: RF_In from PA.Signals out: DET_SIGN to modulation control circuitry.LO_LEVEL to monitor.LF-GENERATORA Field Programmable Gate Array (FPGA) clocked by a 4.9152 MHz oscillator, EEPROM and other digital circuits generate the LF signals.

Communi-cation with the FPGA is done by the IOD[7:0], ~TXRD and ~TXWR signals. Multiplying DAC’s are used to adjust RF level and modulation depth. The keyed LF signal and the RF level is applied to the Modulation Control Circuits. The modulation voltages to the PA is generated by the use of these signals as well as the ON/OFF signal from the AGC and the detected signal from the PA. MAINTENANCE / MONITOR CIRCUITRYThe purpose of the onboard monitor circuitry is to give the Monitor card MO 1374 information about the status of the transmitter. The AMUX_ADR[3:0] from the MO 1374 is applied to the analogue multiplexer. These four lines select one of sixteen possible signals to be measured.The signals measured are:• PA 20 VDC supply voltage• PA current drain @ 20 VDC• Detected RF level from demodulator• Keying envelope from demodulator• Positive/negative modulation peaks• LF AGC voltage• Driver AGC voltage• RF level DC voltage from LF generator• Supply voltage statusThe signal information is sent to the MO 1374 monitor unit as a differential analogue test sig-nal from the MUX.12.1.2 MO1374 Monitor12.1.2.1 General descriptionThe MO1374 monitor is a microprocessor based module. It contains the MB software and forms the basis of the monitor, transmitter control, system maintenance handling and RMS user interface.The MO1374 consists of two submodules:The CPU section includes; CPU, memory, communication ports and an AD converter system.The RF frontend receives a recombined 75MHz AM monitor signal with modulation frequency of 400, 1300 or 3000 Hz, from one or two antennas. This signal is conditioned, mixed and demodulated to produce the output parameters; RF level, modulation level and keying enve-lope. These parameters are monitored by the CPU section.

The RTC shall be accurate within 0.5 seconds per 24 hours.IO BUSThe IO bus is a parallel data bus connecting TX1, TX2 and CI to Monitor 1. ANALOGUE INTERFACEAnalogue monitor and maintenance parameters are passed to the monitor module via the analog bus. The analogue bus consists of differential signal lines from the modules TX1, TX2, PS1, PS2 and CI, and Monitor 1. The TX, PS and CI cards share a common address bus. The differential signals from the different modules are multiplexed into the monitor module AD sys-tem.MEMORYThe memory block contains RAM for data storage, EPROM for the program and EEPROM for permanent system setup parameters.RF FRONTEND:ATTENUATORThis section consists of three resistive π-attenuators, 6dB, 12dB and 16 dB respectively, all matched to 50 ohms. Attenuators are selected by strap settings. Nominal input level shall be adjusted to app. -21 dBm. The section also contains vernier potensiometers within the 6dB steps. The adjustement range for the potmeters is ±4dB.BANDPASS FILTERThe section is equipped with a passive bandpass filter to remove input signals outside the MB channel. Passband: 72-78 MHzMaximum passband attenuation: 0.2 dB.MIXERThe 75 MHz RF-signal is mixed down to 500 kHz to simplify the LF-detection. This is done by the use of a Mini Circuits RMS-2 mixer and a 74.5 MHz local oscillator.The mixer is specified at max. +1 dBm RF in, and the conversion loss is approximately 7 dB.Nominal signal levels:RF in:- 21 dBm 75 MHz AMLO in: +7 dBm 74.5 MHz sine.IF out: -28 dBm 500 kHz AM.LOWPASS FILTERA passive lowpass filter is then used to remove unwanted mixer products, mainly 149.5 MHz.

The low-pass filter is designed as a two pole active filter using one operational amplifier.Minimum attenuation in the stopband (400 Hz - 3 kHz):40 dB.MODULATION LEVEL DETECTORThe modulation level is detected by a peak detector consisting of an operational amplifier feeding a diode and a RC-network. The RF level DC is removed before detection. The time constant of the RC-network is chosen to ensure minimum ripple at the lowest keying fre-quency. The voltage ripple should be maximum 1% relative to nominal output level.KEYING ENVELOPE DETECTORThe keying envelope is detected by the use of an operational amplifier feeding a diode and a RC network. The RF level DC is removed before detection. The time constant of the RC net-work is chosen to ensure a significant difference between the dash/dot output level and the pause level. The output voltage from the peak detector will resemble a pulse train. This pulse train is then applied to a comparator circuit that converts the output signal to an ideal TTL level pulse train.12.1.3 PS1375 Power Supply Module Description12.1.3.1 General descriptionPS1375 is a 100W power module with 120V or 230V AC input voltage and +28V/3.5A, +20V/2.5A, ±12V/1.25A and 5V/6A DC output voltages.

The single antenna may be used for inner, middle and outer marker, while the dual antenna is specially designed for outer markers. The advantage of the dual antenna is a lower spread in FLYING THROUGH TIME inside the localizer coverage area. In addition to two antenna elements, the monitor and distribution network DI 726 is included in NM 3562. Figure 12-9 Antenna block diagramFigure12-10 shows the field strength of the radiated signal directly above the middle marker antenna. Figure12-11 and Figure12-12 illustrate the field strength above the outer marker antenna, using single and dual antenna, respectively. The localizer course sector is scetched. Along an elliptical curve, the field strength is constant. If you look at the diagrams as ordinary geographical maps, you will see that the dual antenna "field-strength-mountain" is steaper and more stretched sideways than the single antenna "mountain". This corresponds to a sharper on/off response on the aircraft's marker beacon instruments.SINGLE ANTENNA SYSTEMNETWORKDI 726RF OUT RF INDUAL ANTENNA SYSTEMRF OUT RF IN5050HBK914-1

The performances og the antennas con-form to ICAO Annex 10 item 3.1.6, and are such that they are largely independent of environment factors such as rain, snow and ice, and they can therefore be located at «diffi-cult» sites. The directivity of the antennas can, if required, be even further increased by add-ing additional elements to the array.The radiation patterns for the antennas are almost unaffected by the surrondings, and the antennas are therefore suitable for offset location where tilting of the antennas is necessary in order to obtain the required signal coverage. (Refer to figure A-1)Figure 12-10, 12-11 and 12-12 shows constant field strenght lines through points in the glide path (GP angle 3º). The marker beacons are located vertically beneath the localizer course line at distance of 1050 m (middle marker) and 3.9 nautical miles (outer marker) from the threshold. The field strengths specified are relative to the maximum level directly above the antenna. The figures show that for an aircraft travelling at a speed of 50 m/s (96 knots) within the maximum allowable course sector of 6º the duration of the visual indication will be within the prescribes limits. The instrument panel lamp should be adjusted so as to switch on or off at the levels indicated in the figures i.e. -27 dB to -33 dB for Figure 12-10, -11 dB to Figure 12-11, and -13 dB to -25 dB for Figure 12-12.The marker beacon antennas are mounted on poles, with the dipoles parallel to the course line. The rear end of an antenna should be at least 2 metres above the ground.The NM 3562 antenna comprises two elements, and is fed via a distribution network (DIA 726) which splits the transmitter power into two equal parts. The network is a coaxial cable hybrid housed in silumine box together with the monitor network which is used to combine the signal from the two monitor probes.
