Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
102 words
A waveguide alignment and mounting assembly comprising: (a) a first waveguide element for receiving signals from a dish and having external threads along an outside cylindrical surface; (b) a disc having a central circular opening defining an internal circular surface, said internal circular surface being internally threaded for mating engagement with the threads on the external cylindrical surface of the first waveguide and said disc having a means for mounting on an antenna dish whereby the waveguide may be set to a selected position along it axis relative to the dish and is held securely in axial alignment by said threaded engagement.
Claim 2
Dependent Claim
