[TowerTalk] REPOST: 6m Moxon and F12 C3-SS Spacing?

[Norm Duxbury]

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!
