- Page 10 OL (for OverLoad, meaning too high of a resistance to measure). If the display shows a low resistance value (i.e., less than one ohm), there is a short in the ® ODU. It has failed and must be replaced according to StarBand Maintenance Bulletin MB-0002.
- Page 11 StarBand satellite. Installing the Mount - When setting up the tripod mount for a 75E antenna, the Step 2 mast must be perfectly plumb. A plumb mast is critical for proper antenna pointing and cross-pol performance.
- Page 12 Antenna Pointing Procedures (continued) Antenna Assembly - Set the 75E antenna elevation and skew to the values Step 3 obtained from Point Dish. See the figure on the previous page, for an illustration of how to set the elevation angle. Tighten the skew locking bolts (4) to a torque of 8 ft-lbs.
- Page 13 Caution Due to the potential for interference caused by VSAT transmissions, the 75E antenna must be peaked using the satellite providing StarBand® service. Failure to do so can cause misalignment with the assigned StarBand® satellite and generate cross-pol interference. ®...
- Page 14 All elevation and azimuth bolts must be tightened to a torque of 12 ft-lbs. Checking for Correct Satellite - Once the 75E antenna is peaked using the Step 8 receive signal and all bolts have been tightened to the proper torque, it is necessary to confirm the antenna is peaked on the correct satellite.
- Page 15 This last item is very important! If the elevation and azimuth angles are not peaked on the receive signal, the cross-pol signal will not be minimized. The StarBand® satellite modem must be online and undisturbed for at least Caution five minutes, before completing the installation as described below.

This can be reflected either in the Signal Quality reading from the satellite modem, lower co-pol, or higher cross-pol measurements.
- Page 22 A missing or damaged O-ring can also allow moisture penetration. The ODU, LNB, and other waveguide screws may be removed to check the O-ring seals. ® ® StarBand Field Service & Maintenance Bulletins StarBand Field Service & Maintenance Bulletins ©2004-2013,...
