Yes, that telephone drop wire is an excellent choice! I use one single cable of
that (normally 2 twisted cables of course) on my 100m vertical antenna in /p. I
have built it up and down several times without any problems...

Betreff: Re: LF: Antenna wire
Tony,
Depends on the un supported span , I think RG58 was used by DL stations a
while ago as 80 mtr dipoles, I use the old 7 strand conduit (35 amp ?) at
home and the 600 ft delta loop at gb4fpr also uses this with 200 ft
sides, some sag has occurred, but the wire is still in place , I'm not
sure if the pvc coating or the location by sea , may be both, causes quite a
build up of static on the Ae
when we replaced the long wire, I used the telephone drop-wire , 4
conductors and 3 steel support cables in a pvc outer , the previous ae used
conduit cable.
I didn't foresee any problems in using the phone cable , the span is 750
feet , took a little tug to get it tight , but there is very little sag
and the electrical performance is quite impressive , Andy's G4JNT cw beacon
reads 3/4 scale on the JRC rx S-Meter and the Q on hf looks to be good ,
although to be fair the wire is 90 foot above the sea/beach , not
proportionally high, but clear of objects
Though I would from my own experience, suggest that addressing the feed and
current distribution in a vertical antenna , be it quite short, may give
unexpected performance on 500.

Subject: 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 ?
