Challenger 6.3m C, Ku, X-Band Receive-Only Earth Station
The Challenger 6.3m Receive-Only Earth Station is a high-performance, large-aperture antenna designed for teleport, broadcast, and ground station applications. Supporting C, Ku, and X-band frequency reception, it delivers high gain, low noise, and 360° polarization rotation.
This RX-only system features a precision stretch-formed aluminum reflector mounted on a hot-dip galvanized steel pedestal. Its rugged construction is rated for up to 125 mph survival wind speeds, while its screw jack drive systems offer reliable 0°–90° elevation and 120° azimuth travel. The system is factory-assembled to minimize installation time and maximize long-term stability.
Made in the USA and engineered for demanding environments, the Challenger 6.3m Satellite RX Antenna is ideal for large-scale downlink operations in any C, Ku, or X-band configuration.
