Product Description

PS-70CM PDF Manual

The PS-70CM polarity switch kit is designed to work with the 436CP30 and 436CP42UG M2 circular polarized antennas. It is NOT compatible with the 436CP16, or any other M2 antenna. It allow 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. There are no frequency sensitive elements in the block assembly so the PS-70CM or its UHF equivalent can be used on most M2 CP antenna from 100 to 500 MHz. The PS-70CM can handle 250W of continuous RF transmission power. 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.
