John. I've had a lot of THHN in the air for ten years or more, and your 
experience is the same as mine. In response to erroneous comments made 
by another ham that antenna performance was degraded by this, N6LF 
published  the results of some serious lab work proving that this was 
not true.

I use THHN #14 for radials, both on the ground and elevated.

Yes.
