Alignment with the satellite is obtained by setting elevation and azimuth. Charts are provided
on page 21 and page 22 to determine the elevation and azimuth values for your earth
station antenna site. “ΔL” is the difference between the earth station antenna site longitude and
the satellite longitude. Use “ΔL” and your earth station latitude to obtain elevation and azimuth
setting.
Use the chart on page 21 to determine your elevation setting.
With NUT 'A' tightened, adjust NUTS 'B' until desired course elevation position is desired. For
quick adjustment, take the weight of the antenna on the boom arm whilst adjusting the position
of NUTS ‘B’ by hand.
Note: this is an approximate setting, the optimum setting will be achieved during fine tuning.
To measure coarse elevation angle place an inclinometer on Face 'E'.
Note: when face 'E' is vertical (90°) the antenna is pointing to 22.6°.
Refer to the azimuth value determined on page 22. Values in the chart must be adjusted
for magnetic deviation for your location for correct compass reading. Partially tighten bolts ‘C’
(enough to align the Az/El mount to the pipe and allow azimuth rotation). Rotate the reflector and
mount on the pipe, pointing it to the compass reading for your location and satellite.
With a spectrum analyser connected to the Rx port of the transceiver, and the transceiver
powered on, sweep the antenna in azimuth for signal. If the desired signal is not located then
increase or decrease elevation setting and repeat the azimuth sweep. When the desired signal
has been found, tighten progressively (1/8 turn each) the 6 pipe clamp BOLTS 'C' until torqued to
30lbft (40Nm).
