CPI Series 1134 1.2 M Ku-Band Rx/Tx VSAT Antenna

CPI Series 1134 1.2 m Ku-Band Rx/Tx VSAT Antenna

The CPI Series 1134 is a rugged 1.2 m Ku-band Rx/Tx VSAT antenna designed to support larger outdoor RF equipment packages. Its long-focal-length, one-piece SMC reflector provides 41.5 dBi receive gain and 43.0 dBi transmit gain with excellent cross-polarization performance. Multiple feed-support options, an optional feed stabilizer and precise Az/El adjustment make it ideal for demanding commercial installations.
