Adjusting antenna azimuth

and elevation

This chapter explains how to adjust the antenna azimuth and elevation for optimum
transmission and reception. It explains mechanical adjustments only. For
explanation of the pointing process for this antenna, see the

JUPITER Antenna

Pointing Guide

(1039429

‐0001). To successfully point the antenna, you must follow

the procedures as described in the pointing guide.

Note:

When acquiring a signal, start with the azimuth and maximize the signal,

then make minor adjustments to the elevation.

Do not pull on the antenna reflector or feed support arm to make pointing
adjustments. Doing so could cause permanent damage to the antenna.
Instead, use the adjustment mechanisms and procedures described in this
chapter.

Adjusting azimuth

illustrates how you adjust antenna azimuth by moving the antenna

horizontally, from side to side.
