Heated dish antennas. |
| 摘要 |
<p>A dish antenna (12) for receiving or transmitting signals, eg. via a satellite, is heated by means of radiant heat from electrical heater (2-5) 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.</p> |
