Hi Tom - thanks for your comments. Disagreements are always welcomed here -
its the only way I can learn something.
The 2WL loop sounds interesting, and could be used by some on the perimeter
of their lots, though the required height might be a problem. How would you
suggest it was fed ? For those who find open line impractical, due to
house-entry etc., is there a way to feed with coax ?
With regard to wire-type, I would recommend people to be on the lookout for
surplus telephone wire, often discarded by linesmen when they are renewing
cables. The stuff here has 4 cores of copper (for the signal), and 6 cores
of steel (for strength) - I use it for my 1WL delta loop on 80, with no
