An antenna dish for reflecting signals for a first antenna operating in a first frequency band is mounted in proximity to a second antenna operating in a second frequency band separated from the first band. With the two antennas in certain relative orientations, the dish is partially or totally in the receiving and transmitting path of the second antenna. The dish is modified so that signals in the first frequency band can effectively pass through the dish. This end result is achieved by placing conductive antenna elements over the entire reflecting surface, these elements being dimensioned to efficiently radiate and receive signals in the first frequency band, thereby permitting such signals to effectively pass through the reflector dish.
