CPI Series 2385 3.8 M Ku-Band Linear Rx/Tx High-Wind Antenna

CPI Series 2385 3.8 m Ku-Band Linear Rx/Tx High-Wind Antenna

The CPI Series 2385 Ku-band is a 3.8 m linearly polarized Rx/Tx antenna designed for high-wind satellite communications. Covering 10.95–12.75 GHz receive and 13.75–14.50 GHz transmit frequencies, it delivers 51.2 dBi receive gain and 53.0 dBi transmit gain. The reinforced four-piece SMC reflector survives winds up to 150 mph.
