Description

The 4BFC (Four-Band Filter / Combiner) takes four 1W or lower inputs and combines them into one output, allowing four transmit signals to share a single multiband antenna.  The 4BFC is designed for the Beacon Blaster and provides filtering of the square-wave BB outputs.  Used with the BB, the output signal harmonic content is well below -40 dBc ( decibels relative to carrier).  Band frequencies are 80, 40, 20, and 10 meters.
