I've got this blind ham friend who lives in a second story =
apartment. I ran
50ft of wire out to a tree from his TenTec tuner and connected the =
rig to a
water pipe ground. He gets RF bites on most bands for obvious =
reasons.
=20
I see TenTec sells a counterpoist tuner. Has anyone dealt with this =
problem
and tried a gadget like this? Here's the link. Look it over and tell =
me what
you think. We can't put up a decent antenna due to restrictions.

The is a much simpler, cheaper solution. Get hold of some FLAT 4 =
conductor rotor cable. (Try Radio shack)
Buy enough to be a 1/4 wave long at your lowest operating frequency.
At ONE end solder all four wires to a solder lug that will fit on =
the ground stud of the radio.
Now measure and cut the OTHER end to be 1/4 wavelength at the lowest =
operating frequency.
Measure a 1/4 wavelength at your next lowest band, and peel back and =
cut off the excess three of the wires.
next lowest frequency two wires and so on....if you operate on more =
than four bands, start another set of four wires.....
=20
Run the counterpoise in as straight a line as possible. You can =
tuck it in the base board or around the ceiling and into the next =
room(s).
=20
Length is not critical and is easy to adjust by adding or cutting =
the wire....
This should take care of RF on the chassis.
