ABSTRACT:
An antenna/downconverter directed to the subscription television distribution industry. The antenna/downconverter (20) includes an integral multidisc director mounted to a housing (51) which defines a reflector cup (54), side lobe suppression ears (38) and a chamber (66) which provides environmental protection for downconverter electronics (184). Received microwave energy is coupled to the downconverter electronics from the perimeter of a receive disc (50) axially spaced from the reflector cup. The housing defines a plurality of jaws (36) which facilitate alignment to variously polarized microwave signals when an installer receives a mounting mast in a selected one of the jaws.
