  • Page 14: Procedures

    6.2 PROCEDURES Follow the steps below in the order shown to assemble the antenna. The site elevation, azimuth, and polarization values should be predetermined and known at this time. Do not tighten any hardware until instructed to do so. Do not touch the front of the reflector. Remove the protective bag in a way so that you do not touch the reflector.

  • Page 17 8. Place the lower mounting bracket onto the end of the feed support and secure with a 5/16-18 x 1.00-inch carriage bolt from above and flat washer, lock washer, and hex nut from below in each of the (2) mounting holes. Tighten securely. See Figure 10. 9.
  • Page 18 Installing the feed support, RA6-TG Radio Assembly Models Feed System 1. Place the feed support (length: 37.6 inches) at the bottom of the reflector and align the mounting hole in the feed support with the center hole in the bottom of the reflector. See Figure 11.
  • Page 19 Attaching the radio assembly 1. Check the polarization-setting dial on the rear of the RA6-TG transceiver. See Figure 14. Make sure that it is set to 0°. If not, set it to 0° now. Reference documents provided with transceiver for instructions for this procedure. 2.

  • Page 20: Antenna Pointing

    7.0 ANTENNA POINTING 7.1 POINTING PROCEDURES This section describes how to point the antenna at the satellite. Correct alignment is critical to the operation of the system. When the antenna is pointed directly at the satellite, it receives a strong signal. If it is not positioned properly, the signal may be weak, and errors may result during data transfers.
  • Page 21 3. Use the vernier scale to accurately set the elevation within 0.1°. See Figure 17. For example, to set the elevation at 17.3°, align the “17” degree tick mark of the scale (seven tick marks past the “10°”mark) with the “0” mark of the vernier. Continue to slowly raise the antenna until the “3” tick mark on the vernier scale aligns with the next closest mark of the elevation scale.
  • Page 22 10. Polarization adjustment is acomplished by Loosening the four 5/16-inch polarization lock down nuts on the reflector support. See Figure 18. Rotate the reflector in polarization until the correct polarization setting is read on the scale. From behind the antenna, rotate the reflector clockwise for positive polarization angles and counter-clockwise for negative angles.
  • Page 23 Azimuth, elevation, and polarization lock down 1. After the antenna is peaked, lock down the azimuth hardware by tightening the two 5/16-inch bolts in the AZ/EL assembly. See Figure 21. 2. Lock down the elevation hardware by tightening the three 5/16-inch bolts in the elevation bracket.

  • Page 24: Installing Vertical Shim Kit For The Ra6-074 Radio

    8.0 INSTALLAING VERTICAL SHIM KIT FOR THE RA6-074 RADIO Out of the box the radio assembly is configured to transmit with horizontal polarization. However, the radio assembly can be reconfigured in the field to transmit with vertical polarization. A Vertical TX Shim Kit, HNS model # VTX-SHIM-KIT, is necessary to make this transformation and is typically packaged separately from the radio assembly.
  • Page 25 2. Once the radio assembly is removed from the feed arm, remove the four Allen screws that attach the feed horn to the horizontal shim and TRIA (Transmit Receive Isolation Assembly). See Figure 24. Figure 25 shows the orientation of the TRIA with a horizontal shim attached. The TRIA would be rotated 90 degrees if a vertical shim were attached.
  • Page 26 3. Remove the horizontal shim and replace it with the vertical shim. The vertical shim can only be positioned one way because of alignment pins in the TRIA. When it is inserted it looks like Figure 26. 4. After the vertical shim is in place, re-connect the feed horn to the TRIA using the four Allen screws previously removed.
