It was probably GTO-15. I would hope that who ever went to the trouble
of adding the standoffs would know the difference. GTO is hard to tell
from RG59 from a distance. Neon sign suppliers even have it in
decorator colors.

What the hell is GTO-15, some West Marine $20/ft trick? This isn't a
neon sign with 40KV of 60 Hz on it....IT'S RF! All the insulation in
the world isn't going stop the RF from leaking out, like it's 'spozed
ta. Lionheart's tuner is hooked to its backstay with a stainless
strap in a gentle curve held on with a stainless hose clamp.

Now that we got the damned steel cable holdin' the boom up replaced
with something that DOESN'T suck off the HF signal into the mainmast,
it works much better......well, at least until the sun exploded wiping
out the ionosphere....

It isn't the RF leaking out that GTO-15 is used for.....

Real Marine Radiomen use PhospherBronze Antenna Wire and GTO-15
as short jumpers where human contact is possible.......

GTO-15 is, highly insulated stranded copper wire, used to connect
antenna tuners to antennas in the marine enviorment. It has 15000V
insulation to prevent flashovers and arc's to ground, from the high
voltage companents of the voltage feed longwire antennas. The 1"
insulators are designed to move the RF antenna away from the Grounded
Backstay and reduce the RF coupling between these two components.
1" isn't enough to really do the job. 6" would be much better considering
the length of the two components, and their parallel coupling.

GTO-15 is fancy sparkplug wire....
