4.3m TVRO antenna

4.3 Meter TVRO Antenna

Model: FS430-R

The AST 4.3m (14 ft) Rx only antenna delivers exceptional performance for receive only applications for C-band and Ku-band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly using matched tooling for interchangeable components. It features an innovative Cassegrain or Ring Focus feed and sub-reflector design which results in high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference. A large center hub provides spacious accommodation for equipment mounting. The reflector is supported by a galvanized elevation over azimuth kingpost pedestal that provides the required stiffness for pointing and tracking accuracy. The pedestals are designed for full orbital arc coverage and are readily adaptable to ground or rooftop installations.

We also offer custom satellite antenna solutions, please contact us for details.
