Ground vs.roof mount - here's my experience.
I have a 32' vert on the ground over a field of 16 radials, each about
20 feet long. Remote tuner, 35' away, allows it to work on multiple
bands.
I also have a 16' vert on the roof of my garage with 4 radials. I tuned
this antenna by connecting 1 radial at a time and then trimming the
radial until I got the same impedance (more or less). Then I connected
all 4 radials and adjusted the vertical radiator to finalize it.
I've done a lot of A/B switching between them on 20 meters. The 1/2
wave on the ground over 16 radials performs equal to or slightly WORSE
than the 1/4 wave on the roof. I've checked both domestic and DX on it
and, as much as I want the 1/2 wave to be better, it just isn't.
At one time I had a Cushcraft MA5V on the roof. The 32' vertical
outperformed it most of the time.
