Instructions given in this bulletin apply to a 12-ft (3.7 m), high-performance, shielded antenna. Antenna maintenance instructions are also included. Feed installation instructions are packed with the feed. The antenna consists of a parbolic reflector, feed, four- section shield, planar radome, and an offset tower mount. Four men and a crane truck are required for the antenna installation. The mount attaches to the antenna at three points and is designed to attach the antenna to an outriggered 4-1/2" (114-mm) diameter pipe. The bottom mounting point is supported by an elevation bolt that provides elevation adjusment of plus or minus 5°. An azimuth strut attaches to one side mounting point of the mount and a tower member. This strut provides both stability and azimuth adjustment of plus or minus 5°. A fixed strut attaches to one side of the reflector rim and a tower member for extra stability. systems required qualified, experienced personnel. Andrew installation instructions have been written for such personnel. Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and condition of equipment. Andrew disclaims any liability or responsibility for the results of improper or unsafe installation practices. Before Installation 1. Uncrate Antenna the crate skid. Remove the items that are accessible such as the feed, shield sections, radome, mount, struts, and hardware kits. Hoist the crate off the skid and lay it down on level ground so that the reflector is facing downward. Remove the rear of the crate, exposing the rear of the reflector, and then the four sides. bracket on each side of the rim. (The top of the reflector is identified by red tape on the rim.) Align each bracket with the holes in the reflector rim. Tightly attach the bracket to the reflector with 12 bolts, flat washers, lock washers, and nuts. Insert the bolts from the inside of the reflector rim as shown in Figure 1. |
