Operating Instructions
2-18 1705A Spectrum Monitor
2. Stabilize the vehiclein a location wherethere will be a clear path between
the antenna and the satellite. The vehicle should be reasonablylevel to
facilitateantenna and polarization adjustment.
3. Point the antenna in the expected directionof the satellite. Note that
compass readings may not be accurate in t he presence of vehicles or
structures. Several readings,at nearby locations, should be taken to
determineany unusual effects. Appropriate correction for magnetic variation
must be made when a magnetic compassis used. The locating tables
indicate truenorth.
4. If the antennaazimuth and elevation are remotely adjusted, the TEKTRO-
NIX 1705A may be permanentlyconnected to the splitter feeding the
L--Banddownlink signal from the outdoor Low Noise Block Converter
(LNB) to the indoor receiver. If the antenna is to be adjusted man ually, a
portable acor 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.
