the 436CP42UG (Ultra-Gain) sets a new performance standard for UHF circular polarized antennas. Gain and F/B are excellent. 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 for matching the antenna noise temperature to modern low noise preamplifiers. 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 O-ring sealed connectors for low maintenance and long-term peak performance. Internal connections are potted in 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 into place with stainless steel retainers. The center boom section is 1-1/2" dia., tapering, front and rear, through 1-1/4" sections to 1" ends. If you are looking for robust construction and top-level performance, for EME use, M2 can supply an optional polarity switch and the necessary parts to convert them to dual-polarity Yagis.
