Reg,

I think you made a typo...if I go with the shorter 5 metre radials, I have
enough wire to put in 66 more radials, not 20. If I stay with my existing
50' length per radial, then I have enough wire for 20 more.

I have the wire. It won't be used for antennas. I have 200 more lawn
staples, so there is no burying, they are "stapled" to the surface, soon to
fall below the "thatch". My 1000' of copper wire has become too valuable to
let sit on spools in the basement. (In case you haven't noticed, copper
prices have gone through the roof!)

So...I'll be putting down either (20) x 50 ft or (66) x 15 ft radials. Don't
worry about my back. When you have a radial plate and a light hammer,
stringing tons of radials is a piece of cake...paying for the copper (in the
future) is going to generate pain elsewhere.

Yes. Use the program to calculate efficiency with the extra 20
radials. Assume all the radials are 5 metres long. But you may not
think the meagre 3% or 0.13dB in efficiency is worth all the labour
and back-ache. By now you are beginning to appreciate how useful the
program is.

Hasan, if I were you I would lay some extra short radials between the
existing long radials - and get some Sloan's liniment to be massaged
into my back. But the increase in efficiency would be un-measurable.
You are fortunate to have very low soil resistivity. Mine is about 70
ohm-metres and for years on the 160m band I have had 7 radials about 3
metres long plus an incoming lead water pipe.
