STEP 3 Place the two halves together, face down, line LIP the pre-drilled holes and place the V4" -20x2" bolts t~rough the three outermost and one innermost holes. See Figure 3. TIGHTEN FINGER TIGHT ONL Y AT THIS POINT. Now make sure all the quadrants are properly joined and flush at each assembly point. THIS IS VERY IMPORTANT TO ASSURE THE CURVE OF THE REFLECTOR IS MAINTAINED AND SUPPORTED CORRECTL Y. Wrench tighten all bolts. PRE.ASSEMBLED POSITION ~ t.. '+ -- - .1-"- Figure 3. Figure 4. STEP 4 You may stand the assembled reflector on edge for easy access to the center. Attach the center hub plates to the antenna by inserting four 5/16"x2" carriage bolts through the front plate, between the ribs, and through the rear plate on the back side of the reflector. Be sure to use 5/16" washers on the rear hub plate. See Figure 4. SECURELY TIGHTEN THE CARRIAGE SOL TS WITH A WRENCH. Figure 5. -----=====- ------ STEP 5 This step involves attaching the quad feed supports. Carefully lay the antenna down on its back so the reflective surface is facing up. Holes are drilled in each reflector section to accommodate the Quad Feed Support. When attaching the quad feed supports to an eight section antenna, attach the feed supports to every other reflector section. Attach the feed supports so the feed horn servo motor will be positioned correctly to the polar axis as outlined in the feed horn instruction manual. Attach the end of the feed support rod with the round hole to the outside perimeter of the antenna (See Figure 5) with V4" -20x1 V2" bolts. The 12' feed supports attach through holes in the face of the reflector. The slotted end of the feed support rod attaches to the feed horn (illustrated in Figure 6) with V4" -20X34" bolts. The feed supports should be positioned equally to properly center the feed horn. You may now set the focal length at 31" for Quad 6 Plus - 36 1/8" for Quad 7 Plus - 46" for Quad 10 - 59" for the STI-12 and STI-16, measuring from the flat center hub plate to the feed horn wave guide. The wave guide is the centermost ring on the feed horn. Adjust the feed horn in or out, by 1/8" increments for optimum Ku band performance. A peak meter is also recommended. Figure 6. .~~ .,,\{) STEP 6 Place the pre-assembled mount over the 3'/2" outside diameter (4'/2"-12',6"-16') ground pole. STEP 7 Installation of the #7 actuator bar is recommended on Antennas for areas within 1 00 East or West of the 1100 longitude line to give the actuator a better mecha~ical . advantage. Installation of the #7 actuator bar outSide thiS area is not required for proper system operation. The proper actuator bar positioning must be obtained so that the antenna will track the entire arc of satellites. To find that position, you must first locate your latitude and longitude on a map. Refer to Chart 1. Add the actuator bar as per Figure 7 or 8, which shows the proper alignment for your location. Secure the actuator bar with (2) '/2 "x1'/2" bolts and locknuts. Now you may install your actuator or hand crank. TIG.HTEN ALL SOL TS WITH A WRENCH. The #7 actuator bar IS not supplied with the 6 or 7 Plus. Attach the actuator directly to the correct side of the elevation U-bracket as shown. Figure 7. SITES \fEST OF II[] L~GITUDE -- Em \EST ___ Figure 8. STEP 8 Setting the Elevation/Declination. Rotate the mount ring on the mount pivot axis until the mount ring is parallel with the elevation U-Bracket (as shown in Figure 9) which will be the highest look angle. Refer to the Elevation/ Declination Chart, find the latitude of the installation site. Note the Elevation (A) and corresponding declination offset (B) angle for the installation site. Set the Elevation (A) first, then adjust the declination (B) to the correct setting for your site latitude. Securely wrench tighten the declination and elevation settings at this time. 4
