FEATURES
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.
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, there is
only one answer: the M2 436CP42 U/G!
