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.

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 ?
