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 modem low-noise preamps. The CP42 is also excellent for ATV, repeater operation, and long haul tropo DX and EME around 432 MHz. The driven element and T blocks are CNC machined, with connectors O-ring sealed for low maintenance and long-term peak performance. Internal connections are embedded in a space-age silicone gel that seals out moisture and improves power handling. The 3/16" 6061-T6 rod elements are centered in the boom to minimize interaction and maintain low ellipticity. Insulators are UV stabilized and locked in place with stainless retainers. The central boom section is 1-1/2" dia., tapering, front and rear,through 1-1/4" sections to 1" ends.If you are looking for rugged construction and top-notch performance, For EME use, M2 can supply the optional parts needed to convert these to dual polarity Yagis.
