This week I wound a simple Beverage RX antenna splitter – 12 turn primary on a 73-202 binocular core, with a 16 turn secondary center tapped and grounded through a 33 ohm resistor. The idea is to share my Beverage switch box between both radios. This should help me with multipliers on the low bands, an improvement over the past where the 2nd radio could only listen on the noisy low band transmit antennas.
Thanks to N0AX for deciphering my spectrum analyzer for me, but it looks like about 4dB of loss through the transformer, with good isolation between both outputs. Theoretically I could get 3DB loss with a Magic T splitter, but this is fine for Beverage antennas. It seems to work well, and it appears I may even be able to do some same-band SO2R with some of the more remotely located Beverages I have.
