FEATURES: 

The 248CP22A 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 like ATV, repeater operation, and long haul tropo DX. 
 

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 im-
proves power handling. The 3/16” 6061-T6 rod elements are centered to minimize interaction and maintain good elliptici-
ty. Insulators are UV stabilized and locked in place with stainless keepers. Rugged construction, uncompromising perfor-
mance for the boom length: that’s the M
