Although it's strong and looks good, I'd think it'd create a much larger
impedance bump. OTOH those impedance bumps are so small at HF, it'd
probably take a lot of them before any of us would notice. Even with
all the connectors I use The AIM shows a healthy return loss and you
really have to look to find the impedance "bumps". So at HF, even with
10 connectors between the station and antenna there is very little loss.

Didn't budge. Try that with the soldered connector.
A properly installed soldered Amphenol 83-1SP makes a pretty strong
connection to the coax. "Properly installed" includes stripping just
enough braid so that it shows through the solder holes and so that the
coax jacket screws into the connector shell, soldering the braid at
each hole so that it flows well, and doing a good soldering job on the
center conductor. Many times, I've had to yank pretty hard on the RG11
attached to high dipoles to guide them away from tree limbs, etc. So
far, I've never had one pull apart.
K3LR has developed a method of soldering the braid to the OUTSIDE of
the connector shell and covering it with heat shrink. That's probably
even stronger! I've done that with a few connectors, but wasn't
thrilled with the result. QST published it a few years ago, and I
think it's somewhere on the internet.
