Interesting and, at times, amusing discussion :-)
To the OP....
Bottom line: JUST ABOUT ANYTHING METALIC WILL WORK
- A length of piano wire.
- A length of coax with shield shorted at one end
- A length of coax with shield shorted at both ends
- A length of coax with shield floating
- A piece of AWG16 insulated wire
- A piece of AWG 1/0 cable
- A length of copper tape
- A length of braided ground cable
-A length of copper tubing
So why is GTO-15 recommended and widely used by most professional installers?
Simply because it makes the most sense.
- its widely available (as neon wire)
- it has 15,000 volts insulation
property and will not arc
, even at high power
- it has good RF conduction properties
- it tends to stand up well in the marine environment
- it's cheap
- it's very easy to deal with mechanically
So....kudos to all the inventive folks who use other materials for the transmission
line to the antenna
For me, I'll continue to use only GTO-15 on my boat, at my home installation
(end-feeding an inverted-L wire), and on my client's boats.
