Why not insulate the back stay and use an SGC tuner?

Hello Rick,
This antenna should perform well and is basically an
impedance matching element, using the DC grounded
backstay and any electrically connected hardware as
the radiating elements. The ability to get a good
match in the ham bands is a bit of guesswork without
doing a complete engineering analysis of the sail
frame, and I am sure that is somewhat beyond the scope
of this project. My guess is that this "antenna" will
radiate very well, and match about as well as any
other radiating system, using a good quality tuner.

Hello to all..
I have a buddy who is searching for an antenna that
might be usable on both
marine frequencies and some amateur frequencies with
the help of a tuner.
He has a pretty big sailing vessel and wants to
utilize the backstay for the
antenna without having to go with the conventional
method of placing
insulators in it. Below is a site describing an
antenna that seems to fit
the bill, however, we are in deep discussion as to
whether it will work well
enough on any amateur frequencies. So, I am asking
the "brain trust" here
for your opinions. If you have a minute, please,
take a look and let us
know what you think.
Thanks,
Rick/K5IAR
