With Low Band Systems PerfoBox DiPlexer two transceivers can share a single dual band antenna for multi-operator contest operation, SO2R operation, field days or any other setup that requires sharing of a 3.5 and 7 MHz multi-band antenna between two transceivers.
Additional band pass filter are required for each input to isolate and protect each transceiver and reduce interference. We recommend using the ultimate performance PerfoBox Band Pass Filters filters for this purpose.
