Tom,
Yeah, I'm resigned to doing something like
that. I just put up a new antenna today,
129' and it's still showing resonance at
1.725, that's way too low. I need to
re-measure the old antenna's length, I put
it up last summer. I do have a few ugly
vacuum variables around here and should
see if I can match with one of them
between the radial plate & feed point.
Enjoy your visit, I love visiting the UK.
73,
