Ian, theres's far too much unwarranted fuss about ground radials in
ordinary English gardens and back yards. Just lay a few wires, 6 to 12
in number. beneath a trodden-on, compacted soil surface, with lengths
of a few metres, perhaps 5 to 10 metres, and away you go.


Sorry, Reg, you have no way to know how many radials someone else needs.

The 'right' radial layout for any given person will depend on their
available space, their resources, their limitations, their style of
operating (casual, DXing or contesting), and above all their antennas -
none of which you actually know.

For example, in presuming that my next radial installation will be in an
"ordinary English garden", you'd actually be wrong on all three counts!


To everyone else out the if you want to know how many radials you
need, go find out everything you can about radials, from every possible
source. There's lots of it out there. With each bit of information you
find, judge its probable reliability and its relevance to your
particular situation. Then make your own decision.

=============================

Ian, may I suggest you join forces with the Ph.D student on this newsgroup
who wants to develop an explicit formula to "Calculate the Earth resistance
in a Multi-layer Ground Structure". Your problems are not unrelated.

And come back in 20 years time to report your unsuccessful findings. ;o)

That is strictly his problem. For my purposes, there's already plenty of
information out there.

I will come back much sooner, and report some successful DXing... though
you're still going to say it could have been done with a dozen short
radials :-)

Ian, I wish you a trouble-free shift of abode. There are always stresses
involved which are to looked-back upon with varying degrees of satisfaction.
I envy you and wish I could embark on the same sort of venture.

Don't forget to take with you program RADIALS2 even if you might not have
the luxury of a back yard.

Thanks, Reg, that's much appreciated.

But it's only lawyers, estate agents, builders, removal men... what's to
worry about?

It's already on my hard disk.

I hear that KY has introduced a heat producing grease.
