Description
The Passive cover is the same PTFE Coated fabric that is used to manufacture the antenna reflector cover. PTFE has the lowest coefficient of friction of any solid, and therefore does a good job of preventing ice and snow accumulation on the feed. For an even higher lever of performance, We offer a Heated Feed Cover. The Heated Feed Cover is also the PTFE Coated fabric that has a 24 VAC, 10 watt Silicon Heater Pad that is located inside the Feed Horn Cover and can operate at 220/230 VAC 1 phase 50 Hz. or 120 VAC 1 phase 60 Hz
