Antenna heating apparatus includes a cover element adapted for covering a signal receiving surface of an antenna, and a heating element on the cover element. The cover element has a body portion which is shaped differently to that of the signal receiving surface of the antenna. The differently shaped body portion 16, preferably having a rear surface which is planar or concave so as to be spaced from the signal receiving surface of the antenna, in use defines at least in part a plenum chamber for heated air between the body portion and the signal receiving surface of the antenna. A method of preventing or limiting accumulation of precipitation on an antenna by use of such antenna heating apparatus is also provided. |
