  Model RPDL4-33-S 4ft Dual Linear Polarized
  L/S/C-band Antenna

• 

This antenna was designed for use with L/S/C-band telemetry requirements but can be used for any other communications requirement within the operating frequency band of the antenna. This 4FT diameter antenna is dual linear polarized, operating from 1.40 GHz to 5.15 GHz. The design incorporates our COTS mount for azimuth and elevation adjustment. The RF inputs are SMA female connectors and are located behind the focal point of the main reflector. The RF ports of the antenna are not phase-matched to one another.
