The PS-2M polarity switch kit is designed to work with the 2MCP14 and 2MCP22 M2 circular polarized antennas. It is NOT compatible with the 2MCP8A, or any other M2 antenna. Originally designed for NASA for many of their 100 to 500 MHz satellite and space craft applications, the PS-2M is now used by many amateur VHF enthusiasts to performance flexibility to both terrestrial and satellite applications.
The heart of the unit is a small, low loss coaxial switch carefully designed into the driven element block. Only one driven element block PS-2M is required to achieve full right hand and left hand selection. The PS-2M can handle 200W. Losses are less than 0.1 dB.
Installation is easy and involves only the removal of one of the original Driven Element assemblies and then mounting the PS-2M in its place.
