ANTENNA MOUNT ASSEMBLY BOTTOM FEED LEG HOLE 2 3 1 FIG. 2.0 - ASSEMBLING REFLECTOR TO AZ/EL CAP MOUNT FEED AND FEED LEGS INSTALLATION Assemble feed assembly and feed legs to antenna as shown in Fig. 2.2. Insert bottom feed leg (4) into hole in bottom edge of antenna (5). NOTE: Bottom feed leg is the one with a slight bend on one end of leg, lance on opposite end, and is shorter than the two side legs (6). Install side legs (6) to antenna. From back side of antenna, secure with M6 x 30mm ( ...” x 1 ....” ) hex bolts and ...” special ( ...” O.D.) flat washer (7 & 8). Do not tighten. Insert bottom leg (4) into hole on center of junction block* (9) until lance on leg is engaged. Insert one side leg (6) into junction block* (9) and secure with M6 x 30mm ( ...” x 1 ....” ) hex bolts and ...” flat washer (7 & 10). Do not tighten. Insert opposite side leg (6) into junction block* (9) and secure with M6 x 30mm hex bolt and ...” flat washer (7 & 10). Tighten and torque bolts securing side legs to junction block and antenna to 4 ft-lbs (5.4 N-m). Tighten self tapping screw (31) with bottom feed leg (make sure screw engages hole in leg). Refer to feed instructions packed with feed to assemble and install the feed assembly. *NOTE: Junction block (9) is packed with feed assembly.

Moisture and DC current cause this type of corrosion. To prevent corrosion, apply a moderate coat of silicon grease to the center conductor and then wrap the entire connection with COAX-SEAL ® Ground pole, antenna mount assembly and feed cables must be grounded in accordance with current National Electric Code and local electric codes to protect from surges due to nearby lightning strikes. The illustration below illustrates a typical grounding method. tape to seal. (COAX-SEAL ® IS A REGISTERED TRADEMARK OF UNIVERSAL ELECTRONICS, INC.)

ANTENNA Alignment with the setting polarization, elevation and azimuth. Charts 1, 2 & 3 are to determine the values for your earth station antenna site. “.L” is the difference between the earth station antenna site longitude and the satellite Use “.L” and your earth station latitude to obtain polarization, elevation or azimuth setting. POLARIZATION OF FEED Loosen feed horn M6 clamp bolts (12) and turn feed clockwise or counterclockwise, depending on being east or west of the satellite as shown on Chart 1. Align marks on the horn clamp and appropriate mark on the horn scale clamp is installed with arrow pointed toward antenna as shown in Fig. 3.0. Keep cable groove on header in the down position when adjusting polarization. NOTE: Single Polarity Feed is factory assembled for vertical polarity. If horizontal polarity is desired, rotate feed 90° (clockwise or counterclockwise). ELEVATION To obtain elevation value for your satellite, refer to chart 2.
