Are you sure that the stepper motors are functioning? The only time that
I've seen high SWR and yet the antenna still functioned properly is when I
had a hairpin match break. I don't believe the MonstIR uses any type of
match, except for a 2:1 balun. Could the balun be the cause? I seriously
doubt it's from your splice, if done properly.

the antenna - a MonstIR - went from 1.3 or so to
3:1 - a big change. What else could make that much difference?
While hardwiring the coax is less than optimal, it seems to me that you
could see the impedance bump with a TDR or similar but the RF really
doesn't
care how it's transported (so it's out-of-balance for 6 inches - so what?).
The feedline is acting like a feedline, it's connected to the antenna
and the antenna is acting like an antenna so I'm trying to figure out what
would cause the SWR jump.
More input appreciated.
Cheers,
Steve K7LXC
