Abstract
A dish antenna for receiving or transmitting signals, e.g. via a satellite, is heated by means of radiant heat from an electrical heater located behind the antenna and spaced apart therefrom. This keeps the antenna free from ice and snow and minimizes distortion. The heater is preferably a self-regulating sheet heater comprising a PTC conductive polymer.
