Low-PIM universal antenna equipment mount

A low-PIM antenna equipment mount assembly comprising:

• a metal mast;
• a pair of pressure bushings, each comprising a cap and a collar received within a receptacle hole in the mast, the pressure bushings coaxially aligned with each other across the mast and aligned with a neutral axis of the mast orthogonal to an axis of main physical load supported by the mast;
• a bolt or threaded rod extending through the pressure bushings and the mast, a pair of fender washers, and a pair of nuts threaded on the bolt or threaded rod, wherein each pressure bushing is captured between an associated fender washer and the mast by an associated nut;
• a metal dual transverse bracket attached to the threaded rod supporting communications equipment on opposing sides of the mast aligned orthogonally to the threaded rod or bolt;
• wherein each pressure bushing is located within the reactive nearfield region of an antenna supported by the dual transverse bracket;
• and
• wherein each pressure bushing suppresses generation of passive intermodulation interference (PIM) while supporting equipment and resisting environmental loads applied by the antenna.

A low-PIM antenna equipment mount assembly comprising:

• a metal mast;
• a plurality of pressure bushings, each comprising a cap and a collar received within a receptacle hole in the mast, the pressure bushings arranged in pairs of pressure bushings coaxially aligned with each other across the mast and aligned with a neutral axis of the mast orthogonal to an axis of main physical load supported by the mast;
• each cap comprising a pair of parallel rails disposed against the mast;
• a bolt or threaded rod extending through each pair of pressure bushings and the mast, a pair of fender washers, and a pair of nuts threaded on the bolt or threaded rod, wherein each pressure bushing is captured between an associated fender washer and the mast by an associated nut;
• an antenna connected to the mast on a first side of the mast by one or more brackets attached to the mast by one or of the bolts or threaded rods;
• one or more pieces of communications equipment connected to the mast on a second side of the mast opposing the first side by one or more metal brackets attached to the mast by one or of the bolts or threaded rods;
• wherein each pressure bushing is located within the reactive nearfield region of the antenna;
• and
• wherein each pressure bushing suppresses generation of passive intermodulation interference (PIM) while supporting equipment and resisting environmental loads applied by the antenna or the pieces of communications equipment.
