M2 PS‐70CM, R/L/SWT FOR UHF SAT
The PS-70CM polarity switch kit is designed to work with the 436CP16, 436CP30 and 436CP42UG M2 circular polarized antennas. It is NOT compatible with any other M2 antenna. 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-70CM 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-70CM is required to achieve full right hand and left hand selection. The PS-70CM can handle 150W. Losses are less than 0.2 dB.
Installation is easy and involves only the removal of one of the original Driven Element assemblies and then mounting the PS-70CM in its place.
