FEATURES:

The 303CP26 is a practical sized, yet high performance circular polarized antenna with a remarkably clean pattern. The
pattern is important in order to match the antenna's noise temperature with modern low noise preamps. This antenna is
ideal for satellite work but is also excellent for terrestrial uses.
The CNC machined driven element module is O-ring sealed and weather tight for low maintenance and long-term peak
performance. Internal connected 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 keepers. Rugged construction, uncompromising
performance for the boom length.
