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.

I used my DX Engineering gift certificate to buy a copy of the "Champion Radio HF
Vertical Performance - Test Methods & Results". I really enjoyed the book and
learned a lot.
It looks like a vertical is the only antenna I am going to get in my terraced
back yard. Has anyone done a similar look at verticals where they looked at
radials vs no radials? There are a lot of claims out there about verticals that
work without radials. The above test looked at some of those antennas but they
were mounted over a radial field...
I am still wondering how I am going to run the radials up the brick terraces,
and they are going to have to be pretty short.
I am ready to listen and learn.
Thanks and 73,
