Thanks for the answers folks, I didn't realise that a small diameter wire
was OK, so that has save me some money as I have a sizeable roll of smaller
cable.
I also have a pair of 6" heavy duty pyrex insulators, also some 3" pyrex and
loads of china insulators of different design, plus I was wondering what I
was going to use for loading/matching coils when Alan mentioned transformers
(thanks Alan). I have a mains line transformer ... the sort you see on poles
for transforming several KV to 220v, which has several miles of copper wire
on two bobbins that I'd completely forgotten about.
Just goes to show it pays to hoard.

Tony,
If it doesn't matter about the weight of that cable, RG58 is not a too bad
idea if there is a need to handle very high voltages. But since you told us
you will have a very long wire your antenna C will be high and so your L
will be low and so your antenna voltage will be low as well. So there is
probably no need to have an extra big wire. You can just take a thin wire,
e.g. 1mm diameter. It has a little more resistance but that doesn't matter
since the overall losses will be much more.
So it's better to take many thin wires in parallel (spaced >1m) than one big
wire :-)

Betreff: LF: Antenna wire
Sorry to ask a stupid newbie question but what is the best wire for my
aerial ?
I had thought about getting a couple of 100m rolls of cheapo RG58 and
soldering the centre and screen together, or is there a better way ?
