Some of the experts on here may disagree, and while I don't think there is
anything magical about hooking up a ground it does do a lot more than
protect you from lightning.  It may not improve your signal, that's not what
I'm talking about, but the ARRL Antenna Book agrees (with your experience,
Tom, and with similar experiences I have had) that a good, low-impedance
path to ground for RF is necessary.  As a practical matter, avoiding 1/4
wavelength ground lengths for every desired frequency of operation may not
be practical so to repeat my original suggestion: "consider a ground "tuner"
like the MFJ Artificial Ground."

OK, maybe you are right.  But, if I don't have the ground hooked up to the
rig and I touch my tuner, the SWR varies.  When I hook up the ground, it
doesn't do that.  And I know for a fact, I have run long wire antennas and
if I don't have a good ground, I get bit bad by RF on the mike.  When I hook
up the ground, it quits.  It must be doing something.  I'm confused!  73
