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 £15 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?
