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.

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 ?
