A 2m/70cm diplexer intended for use in Satnogs ground stations. It is loosely based on the micro-diplexer by kw4fb. In addition to the high pass filter for 70cm and the low pass filter for 2m, this design also included an additional high pass filter at 120MHz, to eliminate interference by strong FM radio broadcast stations. Each antenna input provides an optional bias-tee to power a the antenna's LNA. See the schematic for details.
