My guess is that either your 17M or 20M segment is close enough to a
3/2-wavelength doublet on 6M (as you guess) so that its feedpoint
impedance isn't too terribly reactive. Referenced to a 50-ohm feed,
it might present a feedpoint impedance between 5:1 and 10:1... high
enough that you'll have some significant excess loss on the feedline,
but not enough to cripple your operation.


Dave,

Thanks for your detailed reply, I certainly need to keep down my
losses with only 10 watts and the indoor antenna.

It's probably the 17m segment because it looks as if the 17 comes
out at around 54MHz. As suggested, next weekend I will put up a 6 m
dipole and make comparisons.

Cheers!


Charlie.
