are referring to domestic power lines at that distance, what you say has to be
correct, and all this testing, theorising, and stuff about inverters can
only be written by people who never get to walk down the street in the sunshine.
It is quite clear to anybody who actually does, that the shadow is all, or

also note that the cables are in catenary - another word that doesn't get much
airing.</SPAN></FONT></DIV>

really want to test this, lay a sheet of white A4 paper on the ground so that
what shadow there is passes over it. Then post a 1000 word treatise, complete
with graphs and pictures, on what you see.</SPAN></FONT></DIV>
