Stuart, I dont think I explained myself very well. I agree. From what I
have read, elevated radials are superior to radials on the ground.
However to be superior they need to be resonant.

My understanding of the original post was that someone wanted advice on
radials for a ground mounted vertical. Obviously 1/4 wave radials would
be best here as well but not many of us have the space nor the energy to
plant a large a large number of 1/4 wavelength radials. Since he had 250
feet of wire to play with I felt it was better for him to have ten 25 ft
radials rather than two reasonant lengths.

I believe the ARRL Antenna handbook had a large section on tradeoffs in
number of radials vs. radial length. My recollection was that they
concluded more was better than longer for ground mounted verticals.
Maybe I should revisit the book. If I misread, maybe I will find the
energy to add a couple reasonant lenths and maybe also hook the system
up to my chain link fence.
