CPI Series 1252 2.4 M C- or Ku-Band Receive-Only Antenna

CPI Series 1252 2.4 m C- or Ku-Band Receive-Only Antenna

The CPI Series 1252 is a rugged 2.4 m receive-only satellite antenna available in C-band or Ku-band configurations. Its three-segment SMC reflector provides 37.5 dBi C-band or 46.5 dBi Ku-band midband gain, with greater than 30 dB on-axis cross-polarization isolation. The adjustable Az/El mount supports 360° positioning and survives winds up to 125 mph.
