Tony, If you need a long wire ,
Check out the telephone installers , I found
a trade supplier that was nearly half the e-bay price
for a drum of N-10 drop wire , a 250 mtr
roll came the next day , depends on the intended span ,
700 ft in this case ..
But , long low wires or loops do not
give the expected performance , as Mr M pointed out a while ago,
but as the Ae I have at 'fpr are about 90
feet above the ground and surrounded by salt water
, the Q seems to be quite good , even as the loop
is closer to the fort, a few 1000 tons of yellow sandstone ,I do not
think its particularly damped, quite reactive on HF
Depends on the band and the space
?

Would welding wire do, the CO2 welding wire about
1mm copper coated steel wire ?
That I already have a roll of and it's available in
Lidl this week.

Hello Tony,
there are two problems using RG58 that
way: The antenna will be too heavy. You will never get a minimal sag
even if you could tension the RG58 as it should be. But RG58 as well as the
most other wires ore cables become longer and longer because of their own
weight.
You can buy special antenna litz - good, but not cheap. Or you take
field cable. You can get it as surplus. I bought some hundred meters of field
cable from the NVA (ex DDR military). It is made of copper and (!) steel
wires. So you can tension it very well. I used my first antenna made of field
cable cores for more than six years before it ripped while a storm. My actual
antennas are also made of field cable cores.
The only problem ist that you
have to split the two cores that are twisted with each other. Just take a
fishing swivel, a bit of oil, two empty reels, a good friend and some bottles
of beer to the next soccer field. Fix the one end of the field wire with the
fishing swivel. You can now reel the single lines and the swishing swivel will
turn and turn. After a while you should give a bit of oil on it. Otherwise the
swivel will stop and the lines will be twisted more than before.

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
?
