M2 Antennas 436-CP30

436 MHz 30-Element Circular Polarized Yagi Antenna

A practical sized, yet high performance circular polarized antenna with a remarkably clean pattern. The pattern is important in order to match the antenna's noise temperature with modern low noise preamps. Ideal for satellite work but also excellent for terrestrial uses like ATV, repeater operation, and long haul tropo DX. The CNC machined driven element module is O-ring sealed and weather tight for low maintenance and long-term peak performance. Internal connections are encapsulated in a space-age silicone gel.The 3/16 in. 6061-T6 rod elements are centered in the boom to minimize interaction and maintain good ellipticity. Insulators are UV stabilized and locked in place with stainless keepers.
