Hi
I have now used the R8 for nearly twelve years, 120 or so yards away from
the sea with occasional 60 mile and hour winds, and it is still working
well.
It is guyed at 20 feet.
We used one for the GB90 MGY station to good effect.

Subject: The R7 cushcraft vertical antenna
I ran the R7 on my roof at 20 feet, base above ground, for many years and
was very happy with its performance. I'd like having the R9 now. I've run
other trapped verticals that used full length radials at 20 feet but feel
the R7 was much better even with the short 4 and 5 foot radials poking out
of the base. I wouldn't run a vertical ground mounted. Even ten feet off
the ground is better but in places where I had no room, I ground mounted
them and got out well. For 18 months, I ran a trapped ground mounted
vertical and a 2 watt transceiver and worked all 50 states including both
KH6 and KL7 on 40 meters so ground mounting, even using long ground rods
instead of radials, works better than most people think.
