NGP?   How does that work?   Wave length for CB's is
about 36 ft.  1/2 wave is 18 FT. 1/4 wave and ground
plan is 9 ft. 1/4 wave with base load, I've seen and have
a 48" antenna.  What is this ? 1/4 wave with base load,
and base load ground plan?  I've never heard of it.
By the way, you can still mount ot the fiberglass and
use the body as a ground plan.
