In the true spirit of hamming, just put it up and try it. The tower/beam
might work OK. But, it might not. I once had an R-5 up like that and it
worked great.
I think you will get a lot of differing opinions but at the end of the day
you will only satisfy your curiosity by trying it.

Subject: Re: [TowerTalk] Ground mounting vs roof mounting verticals
Interesting,
I was just thinking of taking my Butternut vertical off the ground and
mounting it to the top of my mast above my Hornet Tribander
at around 35 feet.
So far it sounds like it might just be worth it.
My question would be how would I attach radials to the base of the vertical
like that when my rotor is turning the mast?
Would the tower be ground enough by itself to make the other half of the
vertical or could it work off of the tribander for its
ground and not use wire radials??
