Hi James
I built the kit for of the counterpoise because my
previous QTH was a second floor apartment and the only
ground I had was the baseboard heater pipes. I also
used a long wire and had rf in the shack problems.
The TT counterpoise was the cure. It works great and
got me operating without stray rf and provides a fine
signal. With 50 feet of wire your friend should be
able to work 40 meters on up. The counterpoise wire
can be run alond the baseboard, under carpets etc to
prevent a trip hazard, Just be aware that hi voltages
can be present at the end of the wire so keep it out
of reach of pets and children. I ran mine under the
carpet padding and it worked fine. The kit takes about
two hours at the most to assemble and is fun to build.
Kudos to you for helping a HandiHam to enjoy the
hobby!
If you need any other details don't hesitate to email.
