For those who might be interested, http://kf7p.com/KF7P/Welcome.html sells
Morgan Arrestors and many other excellent products for towers, entrance
panels, grounding, ferrite chokes, etc. He also has an excellent set of
references on his Tech page.
No, no connection to the company; just a satisfied
UG-1185's have captive center pins.

Correct installation is usually the key. The line must be supported no
more than 12" from the connector and NEVER at any time by the connector,
even during installation. Also, line supports along all vertical and
horizontal runs is a must.

I is not always thermal related. Center pin retraction can also be
caused by stress on the coax. I have seen many N male connectors where
the shield has slipped in the clamp due to tension on the coax (from the
weight of hanging or perhaps other causes). I routinely do 2 things -

N are easier to install than UHF (IMHO), easier to tell that they're installed
correctly, and it's difficult to find good quality UHF in larger dia for RG214.
UHF for Heliax are very expensive while surplus NOS N-connectors are common.
That's why I prefer them. I would say UHF offer no advantag

How does that matter for connections inside a weatherproof enclosure
that mounts the arrestors? They also have the problem of cable
migration from the connector.
They handle 1500 V instead of 500 V.

N connectors have better weatherproofing. They handle 1500 V instead of 500 V.
But I mostly like them better because they are engineered instead of a

So does Array Solutions. BUT -- for HF, N connections offer no
advantages over UHF connectors.
