Tektronix 1705A instruction manual City, Satcom K2 G-STAR

Operating Instructions

2.Stabilize the vehicle in a location where there will be a clear path between the antenna and the satellite. The vehicle should be reasonably level to facilitate antenna and polarization adjustment.

3.Point the antenna in the expected direction of the satellite. Note that compass readings may not be accurate in the presence of vehicles or structures. Several readings, at nearby locations, should be taken to determine any unusual effects. Appropriate correction for magnetic variation must be made when a magnetic compass is used. The locating tables indicate true north.

4.If the antenna azimuth and elevation are remotely adjusted, the TEKTRO- NIX 1705A may be permanently connected to the splitter feeding the L-Band downlink signal from the outdoor Low Noise Block Converter (LNB) to the indoor receiver. If the antenna is to be adjusted manually, a portable ac or battery-powered 1705A may be connected directly to the LNB at the antenna, in which case the spectrum monitor can be used to power the LNB.
