The SAT1721 S portable Tactical Common Data Link is a Tx and Rx capable Ku band or X band system. The system includes an antenna controller with cables for connecting the pedestal, an RFE for filtering and amplification of the Tx and Rx signals, a tripod assembly for mounting the pedestal/feed assembly, and transit cases for transporting the entire assembly.

The controller accepts azimuth and elevation angle data and positions the reflector accordingly. The Ku or X band portable TCDL takes less than 30 minutes for two individuals to erect. The antenna is also available without the pedestal as a SAT1710.
