[VHFcontesting] 6 and 2 meter antenna question

I can't really explain it but I know that the Dual band (4 el 6M and 8el 
2M) does work well.  I'll let you know how the Triband unit works out after 
Field Day.  I also would be interested in others who have had experience 
with multi band quads on VHF+ as opposed to short yagis close spaced on a 
common mast.
