Thanks, Barry on helping to wake up my recollections. I had forgotten that
the increasingnes of the spacing of the conductors go into multiple
wavelengths, which as you reminded us, is not practical for HF frequencies.
But for 2-meters and above, it may be worth a try.
The Bamboo suggestion sounds good, by the way. I used to use 300-ohm
twinlead because of the light weight because I wanted the antenna up as high
as possible, and more weight made it droop.

G-line, more correctly known as Goubau line, is not practical for use in
the
HF range. It is generally limited to UHF frequencies and above due to the
physical size of the "launchers" which generate a surface wave along the
line. For details, see: Geog Goubau, "Surface waves and their Application
to Transmission Lines," Journal of Applied Physics, Volume 21, Nov.
(1950).

What I believe Hal is talking about was the early practice of using a
single
wire from the transmitter to connect to an essentially horizontal antenna.
Of course that single wire did not behave as a transmission line, but
rather
became part of the antenna working against ground. In many cases this
wire
became the actual antenna with the horizontal portion acting as capacitive
loading. The resulting antenna pattern is often quite distorted from that
expected of the dipole. A good ground is needed on the transmitter, yet
problems of RF in the shack are common.

find some of that oil they soak telephone poles in then coat it
w/sealer

ultimately wood prob wont last as long as some good plastic and
i guess would be heaver stressing the wires more

it will prob still hold more water than a smooth plastic dunno

and prob not have as good insulative prop's but might be moot
