Hi all, It occurs to me that Steve's aerials is just 12m up....no top load,
so there will be a considerable taper in the current from top to
bottom....not like the heavily top-loaded 'T's and 'L's which are supposed
to have almost constant current in the vertical. Might this difference in
current be just what might be expected in that situation....I think the coil
has to be regarded as part of the aerial. If you assume a linear taper in
current that accounts for about 200mA just by the length of the coil (app.
1m) or its height above ground. Maybe that a bit naive, but then if the
other was losses, that would account for the 400mA.
Fascinating....I am learning a lot.
