A horn antenna is supported by a pair of axially spaced apart trunion assemblies which are rigidly attached to the upper one of a pair of nested ring shaped members, the lower ring member being rigidly attached to a platform. Flat ring shaped flanges on the tops of the members are in contact for rotatably supporting the upper ring member in the lower ring member. Rotation of the antenna is accomplished with a turnbuckle that is connected between the perimeters of the two flanges. Each trunion assembly comprises a bolt that is welded to the top of the upper flange and that has a nut thereon supporting one side of the antenna. Elevation adjustment of the antenna is accomplished by threading the nut on the trunion bolt for raising or lowering the associated side of the antenna.

Adjustable platform mounteed horn antenna

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.
