Hi Bryan re1) You will get this.....ask any patent seeker.
2) it supplemented the mains earth and a couple of
spikes...NB connecting the mains earth made a lot of difference. However
Finbar has an underground armoured to a pole and transformer, and I guess
there is quite a good earth at the pole to protect the transformer. His
counterpoise had this effect as he already had about 1000pF or top-load wire
out (5 wires) Hence my preference in 3 of topwires before counterpoise. I
also believe from the article that Peter quoted in the Handbook that there
is an advantage to earthing the remote end of the counterpoise if it is
under a top-wire. I have no independent tests to confirm that yet.
3) difficult it probably depends on a lot of local factors,
but personally I would put two in the air. Top load can be fan or zig-zag,
and can be relatively light gauge wire as it carries less current, and not
really "radiating current" (that may be contentious)
I hope that helps a bit.

1) every time I have a good idea some other B(oy) thought of it first.
2) Did Finbar's wire replace or supplement the real earth?
3) If you only had a given amount of wire for the horizontal , would you
put:
One in the sky and one underneath it near ground
OR
Two in the sky. and a ground rod.
