Hello,
To the question "does anyone actually take a Moxon portable or roving?" Yes, I 
do. I rove with my 6 meter Moxon in most VHF contests. A full size 3 element 
yagi is legally too large to turn while in motion. It overhangs the truck too 
far. After using a Moxon I would never go back to a HO loop.
73,

Dave - W6TE
