ABSTRACT:
A hub assembly (10) includes a hub (12) which can be attached to the mast (11) of an antenna by fastening assemblies (41) at a selected position along the mast (11). The hub (12) can carry rods (46) in horizontal slots (39, 40) to form a capacitance hat for the antenna, or can carry rods (46) in vertical slots (37, 38) so that the rods (46) can be positioned to overlie a trap (51) by a selected extent to tune the trap (51) a selected amount. Clamping assemblies (47) hold the rods (46) in the selected slots (37-40). Apertures (36) are provided in the hub (12) and are adapted to receive guy wires to support the antenna.
