FEATURES:
The 249CP24 is 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 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 keepers. Rugged construction,
uncompromising performance for the boom length.
