ABSTRACT:
A system for preventing the interruption of satellite communications between an earth antenna and a satellite during inclement weather. The system is comprised of a cover, which covers the antenna and substantially prevents the accumulation of snow and precipitation on the antenna, and a heating system which provides heated air to a space between the cover and the antenna to inhibit snow from sticking to the cover and also to inhibit the formation of frozen moisture on the cover during freezing rain and freezing fog conditions. In one embodiment, the system has an electric, gas or oil heater and a blower system which draws air from the space between the cover and the antenna, heats this air and then recirculates the heated air back to the space. Further, the heating system is equipped with a temperature and moisture sensor unit and a controller. The sensor detects the ambient temperature and humidity conditions which are received by the controller to enable heater and blower system to operate within the predetermined temperature and humidity ranges.
