The wire shielding is made from ground strap, it's available everywhere/. It
is braided tubing pressed flat. Just squeeze it and it opens up, then push
on it lengthwise and it gets bigger. Run your wire threw it and pull it
tight. Someone makes little cans that the unsheilded plugs go in and take
the shielded wire. If you want I'll find out who. I don't go to this list
often, so email me direct.

Folks - First time use of a handheld around my Tcraft. Flipped the
prop and turned on the handheld (using an external ant. mounted below
my feet) and the magneto noise became very apparent. My instructor/A&P
immediately advised that I get a shielded harness and plugs, which
would run about $300. Seems to me that a home-brew solution would be
possible.

Is anyone aware of anyone having done this successfully?

There seem to be two issues to be addressed: shielding the plug and
shielding the cable. I think I can do the latter with shielding taken
off a suitable diameter piece of coax. The question then becomes "How
to shield the plugs?"

Any suggestions are appreciated - Mike
