I used a Force 12 C3SS at my previous QTH. Out of curiosity, I tried it on
6m without any modification. It worked fine, with low VSWR, and I made
several QSOs. Because it worked well, there may be a 6m resonance that will
interact with the 6m Moxon. Have you tried your C3SS on 6? Maybe you don't
need the Moxon!
