Azimuth

Refer to the azimuth value written on Page 3 for your satellite. Using a compass to find azimuth heading, rotate
the antenna and mount, pointing it to the correct azimuth heading for your location and satellite. Tighten AZ/EL
Skew mount clamp bolts until a slight resistance is reached when rotating antenna and mount. Slowly sweep the
antenna in azimuth until a desired signal is found. If the desired signal is not found, increase or decrease eleva-
tion setting slightly and repeat the azimuth sweep.

3.4

Feed Polarization for Maximum Signal Strength

The feed is factory pre-assembled for horizontal Tx polarity as shown in Figure 3.4a.

• If the satellite being used is at 101˚ and horizontal Tx, the factory setting is the correct initial setting.

• If the satellite being used is vertical Tx, then the initial setting should be as shown in Fig. 3.4b, with the

“V” aligned with “0”.

• If the satellite being used is at 129˚ and horizontal Tx, then the initial setting should be as shown in

Figure 3.4c, with the “H” aligned with “0”.

To change polarization settings, loosen the four M4 Phillips head clamp screws one turn and rotate until the “0”
mark on the clamp half is aligned with the corresponding polarity mark on the horn neck.

While the horn clamp bolts are loosened as previously described, very slowly rotate the feed clockwise then coun-
terclockwise until the signal is peaked. Alternately tighten between the four M4 clamp bolts and torque to 12-16
In-lbs. DO NOT OVERTIGHTEN!

3.5

Fine Tuning

When making final adjustments to obtain maximum antenna performance, alternate between elevation, azimu t h ,
and feed polarization fine tuning to reach maximum signal strength until no improvement is detected.

Tighten and torque all remaining AZ/EL Skew mount h a r d wa r e.Tighten all cable ties.
