It is OK to parallel the GTO-15 to the lower part of the backstay
as long as the lower portion of the backstay is not grounded (ie part
of a bonding system). If the lower part of the stay cannot be isolated
for some reason, then the standoffs are requires.

GTO-15 is primarily used in wiring neon signs and oil burner igniters. It
is a single 14 gauge stranded conductor incased in a thick Polyethylene or
PVC insulation. A little over 1/4" in diameter.

Check with a neon sign shop. They will probably give you 15' or at least
sell it sans the "marine" label for a lot less than a chandler will. It
is
exactly the same thing.

BTW, it should not be taped directly to the lower uninsulated section of
the
backstay. Mount it with some 2-3" standoffs. Some very neat standoffs
can
be made from 1/2" plastic conduit. Drill it the diameter of the backstay
every 2" and cut it apart through the holes. Use black zip ties through
the
conduit and around the stay and wire to mount them.

Another hint. Run the wire above the connection point and then back down
to
the clamp. That will keep water from soaking under the insulation and
causing corrosion.

I saw a really nice installation at the Annapolis show. It was a
continuous
black plastic extrusion that had a tube on one side for the wire to run
through and snapped onto the stay on the other. Unfortunately nobody
could
tell me where it came from.

Pull out the coax and replace it with GTO-15 high voltage wire.

Where in the Uk would I buy GTO-15 wire?
