The 418CP30 is a practical sized, yet high performance circular polarized antenna with a remarkably clean patter. The versatile pattern is important in order to match the antenna's noise temperature with modern low noise preamps (LNA). This antenna is ideal for commercial LEO satellite work and was designed with a second resonance band at amateur frequencies of 335-338 MHz, with a peak gain of 16 dBic. 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 that seals out moisture and improves power handling. The 3/16" 6061-T6 rod elements are centered to minimize interaction and maintain good ellipticity. Insulators are UV stabilized and locked in place with stainless steel keepers. Rugged construction, uncompromising performance for the boom length, that's the M2 418CP30.
