Orbital Systems provides a wide range of antenna feeds for Earth Observation Satellites (EOS) Direct Broadcast (DB), Telemetry, Tracking and Control (TT&C), and general telemetry applications.  All Orbital feeds are made of the highest quality materials and are enclosed in a heavy duty aluminum enclosure, powder coated and assembled with stainless steel fasteners to eliminate external corrosion.  Feeds are pressurized with temperature and humidity sensors, and built in purge valves to ventilate the feed when excess humidity is detected.  Feeds are precision matched to the antenna system.
