The PS-2MS polarity switch kit is designed to work with the 2MCP8A and 2MCP12. It allows instantaneous selection of right or left hand circularity. Originally designed for NASA for many of their 100 to 500 MHz satellite and space craft applications, the PS-2MS 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 PS-2MCP8A per antenna is required to achieve full right hand and left hand selection. The PS-2MS can handle 200W of continuous RF transmission power. Losses are less than 0.1 dB.

Installation is easy and involves the removal of one of the original Driven Element assemblies and then mounting the PS-2MS in its place.  M2 Antennas has polarity switches available for our commercial antennas for popular frequencies.  Polarity switches can also be designed for any of our custom antennas based on your requirements.  Please contact us with your requirements.
