3.7 M L, S, X BANDS AND MULTI-BANDS DBS ANTENNA

Probecom 3.7M Ring focus antenna provides Tx/Rx 2-port feed, 3.7m DBS band antenna only for linear polarization, can deliver exceptionally high performance for transmit/receive applications.

Probecom 3.7M antenna RF specification can adhere to FCC Regulation25.209, IESS and ITU-RS.580-5, INMARSAT, ASIASAT, INTELSAT, APT and CHINASAT, etc.

Probecom 3.7M antenna reflector incorporates stretch-formed doubly contoured panels with matched radials and hub for ease of field alignment. The standard designed azimuth over elevation pedestal provides a cost-effective solution for high stiffness and stability, full orbital arc coverage and fine drive performance, and ensures the pointing accuracy required for DBS band operation.
