Have you thought about going the loop antenna
route to cut down on the noise??

--Mike L.

Absolutely - first a big horizontal loop that I can build pretty
cheaply, just a matter (now) of finding the time and proper routing.
It will necessarily include my entire house within the loop, including
part of the support structure, so I am hoping for the best but
expecting the mediocre.

Then, if all else fails, trying out a commercial small amplified
vertical loop, like the Wellbrook.

I do use a dipole that works pretty well on the higher bands (11 MHz
and up), and since installing a transformer on my random wire I've
noticed a *slight* decrease in noise on that aerial - but it ain't
enough. I am surrounded by RF junkola, some of which will *never* go
away (like high-voltage lines front and back yards and splattery 50 kW
MW transmitters a couple miles away, gushing harmonics like a
fountain).
