Dual-reflector Earth Station Antenna
This dual-reflector earth station antenna (ESA) supplies good performance for high density data, voice communications networks and broadcast applications. The antenna's dual-reflector Gregorian optical system gives high gain and closely controlled pattern characteristics. Available in C- or Ku-band capabilities, the 6.5-m ESA includes a self-aligning main reflector to eliminate the need for field alignment and a two-port circular receive and transmit C-band combiner that can be field-switched from circular to linear polarization. Stainless-steel hardware provides maximum resistance against corrosion. A wind survival factor of up to 125 mph (200 kph) in any operational position is guaranteed.
