Adjustment device for platform mounted horn antenna

摘要

A pair of bolts are welded to axially spaced apart points on a base plate in an upright position to provide fixed reference points for supporting a horn antenna. Axially aligned trunnion pipes on the antenna are rotatably attached to an associated tubular enclosure at points corresponding to the locations of the bolts. Each of the bolts extends through an opening in one side of an associated enclosure, with the one side being sandwiched between a pair of nuts. Elevation adjustment of the antenna is accomplished by rotating one of the nuts for raising or lowering one of the enclosures and the associated side of the antenna. The elevation of the antenna is maintained by threading the associated other nut of the pair thereof against the side of the enclosure.
