I purchased two 125 foot long lengths of DXE RG8X, direct burial coax, this
was two perhaps three years ago. The coax lays on the lawn, I pick it up to cut
the grass, so I disconnect the cable weekly in the summer. I noted a high SWR
on the 20 meter antenna and thought I had not tightened the Crimp on PL259
connector tight enough to the relay. Checked the antenna and all was fine. The
next week the same problem occurred after reconnecting the coax to the relay,
High SWR on the 20 meter antenna. I took out the antenna analyzer fed the
antenna direct bypassing the relay, same problem high SWR. So the problem is at
the antenna or with the cable. Before looking at the antenna I again checked
the cable wiggling the DXE cable right at the crimp on connection, about three
inches up from the connector, the SWR was very high or low, the crimp on was
not making proper ground to the cable, hence an intermittent connection. I did
re-heat the center conductor and re-solder it just in case but no effect. I
don't have crimp on tools here and could not leave the connector on so I cut
the crimp on off, put on a PL259, re-soldered everything and brought in all my
tools and chair. This occurred two weeks ago, its snowing here today.

I wonder what issues that you have had with Amphenol connectors and with
which style?
My station uses various styles, N, UHF and 7-16DIN (plus BNC on RX cables).
I only purchase Amphenol or Andrew/Commscope coax connectors and they all
have been reliable.

Amphenol connectors are Banned at my station. They are Not what they used
to be...
100% of all Up the tower jumpers are DXE RG213 and DXE Crimp ons.
