A number of years ago I had a Gap Eagle DX. It worked fine and has no radials.
It worked from 10-40 meters. Full power on 10,15,17,20 and I believe 400 watts
on 40. It was on a flat metal roof mounted on a 7' tripod. The roof was about
20' high. I had the Gap Eagle up for about 4 yrs. and then sold it to a ham
friend of mine that was just starting out. He mounted it on the roof of his
house and has great success with it. Again no radials required.

Subject: Re: [TowerTalk] Vertical Antenna Question
The Cushcraft R7/R8/R9 Verticals are 1/2 wave so they do not require radials.
I have one up and it works fine without any radials. They work better if you
can get them up in the air about 10ft or so. Any antenna is better than no
antenna but a vertical that requires radials and you don't have any is probably
not going to work well.
The SteppIR verticals are pretty popular and if you are going to use ground
radials Just try to put out at least 16 to 32 of them as long as you can. If
you have to go around trees other blockages then do so just keep the radials
spaced equally apart. Short ones of 8 ft are fine in some directions too.
There are plenty of options even in a terraced yard. Can you put up a self
supporting pole? What is the budget and what bands are you wanting coverage.
