Model No: 393CP18
SPECIFICATIONS:
*Subtract 2.14 from dBi for dBd
FEATURES:
The 393CP18 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 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: that’s the M
