Hi All.
I've tried various insulated stranded copper 'equipment' wire which is OK in 
short runs, or for a short time.
The Whitton club antenna, and the /P antenna used at Hastings is standard 
hard drawn copper in UK 16 gauge ( apx. 1.7mm dia )
The clubs 234 foot has been in place for 2 years without problem but the 
extra tension to raise 300m would be considerable.   Price here is Ł15 per 
100m.

The resistive losses in the antenna should be minor compared to the losses in 
the coil / ground system.

How about a thin steel cable under a lot of tension, used to support a lower 
loss copper radiator. As in power distribution between pylons?
