OTOH, that's just failure. The efficiency of transmission has
got to be a whole other issue - which I have no clue about. --


Again done correctly, the crimp will have almost no differance
than a single piece of wire. The solder will have a very small
ammount of resistance.

Probably did not come out the way I want it to, but the crimp
will have less resistance than a soldered joint.


That's why a proper soldered joint is first crimped. Solder holds
and seals the connection. That's the way I was taught.

I can make some pretty poor soldering at times, but I can also use
proper technique. I passed a NASA soldering school class.

Who says a solder connection does not need proper strain relief to
prevent vibration failure.

I have soldered large battery cables using hundreds of watts, as
well as 1.5 mm caps to boards.

Our "radio guy" for all the state 2-way radios installs them with
crimped connections as far as hooking them into the car electrical
system, no soldering.

I only solder them when they really need it. Otherwise, I use my
ratcheting crimp tool and crimp the insulated connection and cable grip.
The more expensive connectors have a metal sleeve under the cable grip
insulation. ^_^
