- SPECIFICATIONS
The probecom 1.8m satellite antenna delivers exceptional performance for transmit/receive and receive only applications for L through Ka-band frequencies. This VSAT satellite dish parabolic antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly using matched tooling for interchangeable components. It features an innovativeoffset feed 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.
Highlighted Features:
*Meets CCIR 580 and INTELSAT Requirements
*High precision alloy aluminum main reflector.
