ABSTRACT:
A frequency agile transmitter antenna combiner is disclosed that allows combining multiple transmitter outputs onto a single antenna feed where the transmitters are operated at multiple frequencies. According to the invention, a method is disclosed and an apparatus is described for receiving a plurality of RF signal inputs where each input may contain any of a predetermined set of frequencies. The input frequency is then coupled to a frequency splitter that couples the input frequency to a dedicated combiner that tends to isolate the RF inputs from each other. The signal is then coupled to a combiner output, and ultimately to a single antenna feed line.
