The 436-CP42 U/G (Ultra-Gain) sets a new performance standard for UHF circular polarized antennas. Gain and F/B are excellent. The boom length is matched to the 2MCP22, and together they form an unbeatable satellite communications package. The extremely clean pattern maximizes forward gain and F/B. The pattern is important in order to match the antenna"s noise temperature with modern low-noise preamps. The CP42 is also excellent for ATV, repeater operation, and long haul tropo DX and EME around 432 MHz.
