Model No: 300XP12 

FEATURES: 

The 300XP12 is high performance circular polarized antenna with a remarkably clean pattern. The pattern is im-

portant in order to match the antenna’s noise temperature with modern low noise preamps. This antenna is ideal for satel-

lite 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 connected are encapsulated in a space-age silicone gel that seals out moisture and improves 

power handling. The 1/2” 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 performance for 

the boom length: that’s the M
