The two Amateur Band Transmitters are 100KHz spaced with the commercial box more than 10MHz higher. To keep things short and sweet, the close spaced Amateur Transmitters are probably best done with a 2 port hybrid. Depending on your resources... the hybrid output would more often be bandpass combined with the 464 commercial box path. All this can be done on one or two antennas, just takes the proper hardware in place and a lot of homework. Making it fit into a very space limited cabinet is the magic trick. cheers, s.
