The SPIDER is an innovative, antenna mounting system, with a wide range of convenient mounting options, and accessories.

Enclosed in a weather-proof, die-cast aluminum case, using Lap joint construction, to provide protection against dust and rain; while providing excellent EMI/RFI shielding.



The SPIDER’s octagon enclosure, uses 8 x 3/8-24” solid-brass connectors, to accommodate up to eight ham stick type antennas. Each set of Ham Stick antennas, form one-matched (dipole) pair; for one of four-bands; Positioned around a central hub.
