I have never had a problem with soldering PL-259’s and I have been putting them
on since 1959! I know how to soldering them correctly.

I've been shopping for them. You need a minimum of 1 1/4" depth for
the PL-259. That rules out all the cheap ones. For ~$300

It depends on the duty cycle, length of transmission and vswr.

Hmm, how do solder that center pin if you can't pull it out of the
connector? If it comes out of the connector easily, it's not a true
captured pin connector (which is made for solid center conductor coax
like LMR-400, LDF4, etc.), not RG-213, etc.

Well here's the advantage of captivated center pins: the pin is NOT
bonded to the center conductor. IOW, if the coax center conductor
shrinks a bit, it can slide in the center pin and the pin stays put.
And that's exactly what you want it to do - especially with an N connector.

Perhaps you are looking at the N connector lead, the actual pin where RF
flows is Ø.120 which is not much smaller than a UHF connector (Ø.156). I
use a number of N connectors at my station and have no issues.

Hi all,
I can confirm Martin's and Greg's experiences. It is strongly recommended to
avoid
using the PLs at all. I did the same changes and since that no problems at all.
Of course any adapters are avoided too. All cables must be properly assembled
with proper
and high quality N-connectors.
I agree with Rick,
If an N connector is not designed to fix the relationship of the center pin
(soldered to the center conductor) to the body it should not be used
outdoors or on long runs of unburied coax exposed to full seasonal
temperatures.
I learned that the hard way on unfixed pin N
