A transmitting and receiving apparatus comprises a transmit/receive feed operable to transmit signals to and receive signals from a source, a waveguide assembly coupled with the transmit/receive feed for propagating transmitted and received signals to and from the transmit/receive feed, and a receive isolation filter coupled with the waveguide assembly and operable to filter the dual-polarized received signals without separating the two components thereof and to provide the filtered dual-polarized received signals to a receiver so as to isolate the receiver from signals transmitted by the transmit/receive feed. Thus, both components of the received signals are filtered simultaneously along the same path of propagation, eliminating the need to split the components along separate paths, separately filter them, and then recombine them as in prior antennas.
