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 ?
Tony, EI8JK
