Abstract
A appartus for deicing a reflector type microwave antenna. The appartus includes an infrared generator placed behind the antenna dish and a paraboloidal reflector. The infrared generator acts as a point source at the focal point of the paraboloidal reflector emitting radiant energy away from the antenna dish onto a paraboloidal reflector. The paraboloidal reflector reflects the radiant energy parallely to the principal axis of the reflector onto the rear surface of the antenna dish to uniformly heat the antenna dish.
Claims11
An apparatus for deicing an antenna dish having a front surface and a rear surface, said apparatus comprising:
- paraboloidal reflector means located behind said dish rear surface for reflecting radiation onto said dish rear surface to uniformly heat said antenna dish,
- radiant heating means located between said paraboloidal reflector means and said dish rear surface for emitting said radiation towards said paraboloidal reflector means,
- said paraboloidal reflector means having a principal axis and a focal point located on said principal axis,
- said heating means positioned on said principal axis between said paraboloidal reflector means and said focal point wherein said paraboloidal reflector means reflects said radiation emitted from said heating means substantially parallel to said principal axis onto said dish rear surface.
