I vote all 3 crimp it clamp it and solder it.
make a good mechanical connection - then solder it.

Don't forget to add Loctite, spot weld, drop forge, nuclear laser,
explosive forming, refractory conditioning, epoxy, RTV, sixteen
layers of Scotch #33 tape and the Pope's blessing.

Those who are non-Catholics have a problem. :-)

Make that Scotch #33+ pelase....

Negative
Scotchfil insulation putty, followed by Scotch 88+ (as opposed to 33+)
scotch 88 is weatherproof.
Then a little Scotchkote insulating varnish.
Then take it all to a motor repair shop and send it through the VPI process.

no to welding
no to loctite and RTV

So anyhow, why are crimps inferior to soldering?

I recommend cryogenic processing of all coax connectors !

I will inevitably be needing in the future. I am planing on using only
LMR style coax 240, 400, 600 and maybe some 900 if I get into the 1.2ghz
stuff. So is it better to use the crimp, clamp or solder on
connectors. In the case of the center conductor, there are some where
that is solder and the outer is crimp or clamp so is crimp and or clamp
ok for the outer conductor and solder better for the inner? I welcome
all points of view on this. Thanks for you input.


USA DOD and NASA [DOD STD 454 et al] specifications insist that both a
secure and stable mechanical connection, crimp or clamp, be used for
strength, temperature and fatigue stability; and, that solder or weld be
used, occassion appropriate, for electrical connectivity.

In the typical amateur usage that would include a strain relief [crimp
or clamp] for those connections where a mechanical stress [bend or
weight] and solder.
