I have a Hy-Gain Hy-Tower on top of an all metal barn. Base is about 23 ft
AGL. I have no radials. It works pretty well. I got a recommendation to
put at least 4 radials on the roof (2.5:12 pitch gable roof) and preferably
4 cut for each band that can stay on the roof (roof is about 38x74 feet and
ant is dead center.) Thoughts?

Mike, I forgot to say the top loading can give your HF-2V a low VSWR across
the entire 40 M band or across the entire phone or CW portion.... great for
contests!

I have an HF-2V ground mounted with 32 - 40 foot radials under it. When I
went from 16 to 32 radials, 80 became significantly more touchy to tune.
That said, it works very well on 40 and 80 into EU.
This weekend I plan to add 4 -12 foot wires for a top hat for 80.
According to Bencher, it will improve performance on 80 as well as a
little more bandwidth. Anyone tried this?
Thanks

James,
I recently installed an HF9V at around 8' AGL. I use 2 elevated
"ground"(counterpoise) radials per band, sloping from 8' down to about 5'
AGL.
I find it works VERY well on 40m and up and adequate on 80m.
Over the past month, I've compared it to a host of other wire antennas at
similar heights and always found the Butternut to be as good or better
than anything else in the yard here. I believe the raised radials have
less
loss, but it was twitchy to tune. An HF2V ought to be a cake-walk to
tune.
It's just my opinion that using only a few ground radials is lossy and
that's why everyone preaches ground mounting it. (a lot easier to tune w/
better/wide 2:1 SWR curves) (I use the term "better", but I don't really
mean better, but it is better for the match, but I think it's like dumping
power into the ground to heat worms.)
So far I have around 2500 Q's with it, contesting every weekend and I am
sure it works well , raised up like it is.
p.s.- subscribe to the Yahoo group for Butternut antennas and then check
the
files section for "VE9AA" or "AD5X".a couple good ideas
how to get the whole 80m band out of the antenna.
YMMV,
