Hi Dave,
Other than that failed experiment with FlexWeave when I got back on the
air in 2003, I've never used anything but THHN for wire antennas. For
low-stress applications (not very high, no tall trees involved), Our
dipoles for FD, that get strung between ad hoc skyhooks or to ropes
launched into low trees are all #14 THHN solid. I've been happy with
#14; for my high dipoles suspended between very tall redwoods and fed
with 150 ft or more of RG11, I've settled on #8 bare copper, stretched
so that it approximates "hard drawn" and about #9. I've done this
because even #10 stranded or solid stretches under tension, so I had to
lower the dipoles every few years to snip a few feed off the ends.
#14 solid should be just fine for your application. Just be prepared to
tweak length every few years. :)
