Reg - any increase in signals certainly did not increase enough to overcome
the noise. Like I mentioned, the original configuration I is very quiet.
In fact, the noise level went from not registering on the meter at all at
the lower height to an S9+ when I raised the antenna.

Hi Warren,

Then it appears you upset the balance of the antenna (hard to believe
it was balanced before) such that common mode noise is finding its way
in.

It seems entirely unlikely that you achieved any more gain, nor more
highly resolved angular discrimination to now be focused on a source
of noise that has "always" been there.

The way I read your statements, it's as if you raised your antenna to
the equal horizon of a noise your antenna in its former position just
couldn't see. At HF and at those heights, this just isn't in the
cards. Signal intensity follows square law and for your noise to rise
from nothing to S-9 does not correspond to any dimensional change (or
if it does, there's your clue, but you are within inches of it now
where you were 10's of feet away formerly).
