FEATURES:
The 418CP30 is a practical sized, yet high performance circular polarized antenna with a remarkably
clean pattern. The versatile pattern is important in order to match the antenna's noise temperature with modern
low noise preamps. This antenna is ideal for commercial LEO satellite work and was designed with a second res-
onance band at amateur frequencies of 335-338 MHz, with a peak gain of 16 dBi. The CNC machined driven
element module is O-ring sealed and weather tight for low maintenance and long-term peak performance. Inter-
nal connected are encapsulated in a space-age silicone gel that seals out moisture and improves power han-
dling. The 3/16" 6061-T6 rod elements are centered to minimize interaction and maintain good ellipticity. Insula-
tors are UV stabilized and locked in place with stainless keepers. Rugged construction, uncompromising perfor-
mance for the boom length: that's the M
