Hams are WAY too obsessed with SWR. If it's a full size half wave, the
difference between an antenna resonant at 3615 and 3515 wouldn't make a bit of
difference in performance.
VSWR at 2:1 or less is perfectly OK. Even 3:1 will have negligible effect on
the signal if it doesn't trigger a fold-back feature in the radio.
I use open wire tuned feeders on mine, and get equally excellent results all
the way from 3500-4000, but I use a remotely tuned matching network at the base
of the tower. If I wanted to use coax, I would purchase some hard-line (ever
cable TV stuff works fine), cut the antenna to be resonant at 3750, and just
use it and not worry about it.
