Tim, I solder these on the N connectors all the time with no problems.

In past life, in a land far far away (Smog Angeles), I once worked for
and later ran a comm shop. *At the time, UG-21/U male N connectors
were commonly available and in fashion. *Our 460MHz repeater systems
were full of them so I had plenty of experience in soldering,
assembling, and repairing these connectors. *I don't want to remember
all the 25 mile joy rides up the fire road to Santiago and Mojeska Pk
just to fix a problem caused by a flakey UG-21/U coax connector. Well,
to be totally accurate, I had equal problems with soldered PL-259
connectors. *I fought these problems for years because I assumed there
was no better way.

Meanwhile, I was also involved in an avionics shop (on the business
end). *They were slowly switching from soldered to crimp type
connectors. *The owner insisted that is was worth the effort because
the number of connector failures and rework had approached zero with
the crimp type. *I became a believer overnight.

Many years later, I designed a few marine radios for the USCG. *The
specs would tolerate either solder or crimp. *So, I asked which they
preferred. *Crimp was the answer, because they never could teach the
techs how to properly solder a connector, while the crimper always
does it right. *All our radios used crimp connectors, even on the
inside.

Roll forward more years and we have 10Base2 and 10baseT ethernet. *The
former uses UG-21/u N connectors. *The latter uses BNC. *The nice
yellow coax cable with the flakey connector was a constant source of
headaches. *The crimp type BNC's never failed (unless abused).

I'm not sure what to suggest. *With skill UG-21/u can be made to work.
With luck, they can even be kept working in the field. *However, I'll
take crimp type any day, especially after many year of experience
dealing with both.

I dont have a problem with crimp on terminals just that where I work
someone has always borrowed the crimp tool just when I need it. I
always have my trusty soldeing gun handy, no one wants to borrow it.
For me one is as easy and works as well as the other. The biggest
problem I have with the non crimp type is the shield is eventually
cut from the connector. The ones at work that are disconnected weekly
for preventive maintenance have only lasted about 20 years before
needing the connectors replaced, BUMMER. The crimp-on type are not
without their problems. I was doing an inspection after some equipment
installation and was able to pull the the ends off of 20 BNC
connectors. The inspection stopped at that point and the decision was
made to reaccomplish all of the connectors, about 200 of them. The
installer was not happy. The problem turned out to be a bad crimp
tool. Like the solder-ons if done properly they are both reliable
connections.
