JP,
As you increase the diameter of the wire, so goes the Q; larger wire
will have a higher Q. Q=XL/R
I am lucky and have a pine tree to connect the apex of an inverted V for
40M . The two ends go to the sides of the fence.

Greetings,
I am building a 40/80 EFHW antenna that uses a loading/choke coil at the
end of the resonant length for 40 meters. Another 25 meters of wire is
then added to the far end of the coil. I will never run more than 450
watts peak SSB through it. The plan I'm using as a guide calls for 19AWG
magnet wire for a coil built on a 1.5 inch form and measuring 110 uH. 76
turns of wire to get there.
Now to antenna physics. Does the coil wire at the end of prox.65 feet of
antenna really have to be that fat (19AWG). It seems like the current
and the voltage would both be pretty low there and a much finer gauge
(read less expensive) of wire would probably be okay, but I'm certainly
not sure of that. Any thoughts?
