3. CAUTION - The foundation design shown does not represent an appropriate design for any specific locality since soil conditions vary and may not meet design criteria given in Note 1. You should consult a local professional engineer to determine your soil conditions and appropriate foundation. ASSEMBLY AND INSTALLATION The AZ/EL Cap Mount can be installed on a 2C\,”or 3” O.D. ground tube, roof, or wall mount depending on model. The appropriate mount should be assembled and in place before installing the AZ/EL cap. As the AZ/EL cap mount is factory preassembled, there is no assembly required for the mount. ASSEMBLING ANTENNA TO CAP MOUNT Install four M8 x 60mm (2C\,”) carriage bolts (1) into holes in center of reflector and assemble to cap mount flanges. (Reference Fig. 2.0) Install four lock washers (2) and hex nuts (3) on bolts. Tighten and torque to 11 ft.-lbs (15 N-m). IMPORTANT! Bottom feed leg hole to be located as shown in Fig. 2.0. INSTALLING CAP MOUNT ON MOUNT TUBE Lift reflector/cap mount assembly and slide cap mount onto mount tube (Reference Fig. 2.1). Swivel antenna assembly until reflector faces southward. Tighten M8 clamp nuts so that the antenna assembly is held stationary on tube, but can be swiveled with slight pressure. 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 (Z\v”x 1C\zn”) hex bolts and Z\v” special (M\,” 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 (Z\v”x 1C\zn”) hex bolts and Z\v” 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 Z\v” 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® tape to 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. Clamps that provide a solid connection between ground wire and ground source should be used. ANTENNA ALIGNMENT PROCEDURE Alignment with the satellite is obtained by 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 longitude. 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. Loosen bolts in curved slots of AZ/EL Housing Z\, to Z\v a turn (Ref. Fig. 3.1). Turn elevation adjustment bolt clockwise to decr...
