I was thinking of using one of those bi-ocular transformers that's found in many solid state transceivers .... but changed to 1:1 and basically an C L to ground and the other half of the 1:1 would be L C Into the GS-35B .... guess ill just try it with a dummy load and my MFJ259b ..... at least ill know the frequency range of the 1:1
