Hi Jan,
In late 80's we were bitten by the 160mtr bug.
Put up a Rohn25 to 125ft with about 10 radials..
Didn't take long to recognize that we needed some improvement in radial
system.
Being on small farm and having the room and the trees,
We put up two temporary 160 mtr dipoles for test purposes.
We set up a TS830 at friends house about one mile ,LOS, away for field
strength readings.
Using ten watts transmitted, all three antennas were about same on S
meter at the TS830.
Days later, with 60 1/4w radials installed, it took 100w into the
dipoles to
get same reading as with 10w into the vertical.
I can't prove this with 'theory',
but theory never works very well on a chicken farm anyway.
