Default Stronger solder?

Hi, i'm trying to repair my TV. The coax cable adaptor broke off, and i'm
trying to reattach it. I've tried soldering it, like i've soldered many
other things, but this does not seem strong enough to hold it in place.
Is there a better solder, or a better method of reattaching it? It needs
to be pretty strong because the tv coax cables are pretty thick and not
very flexible. Any suggestions would be appreciated!



Large surface areas are difficult to solder properly using garden-variety
radio/tv solder. Make sure you're using sufficient heat -- which would be a
gun type iron, 100-200W or higher depending on how much metal you're trying
to heat up. And don't skimp on the solder. If you're trying to solder huge
areas with small diameter solder, you'll have to feed the solder very
quickly. Also, try using flux on the area first, as no amount of solder
will stick well if the surface isn't clean.

As a last resort, you can try acid core solder. Never ever use this stuff
on circuit boards or part leads, but for large metal areas like shielding
cases and nuts/bolts, it's ok to try.

You might also consider using a quick-connect type connector on the cable.
This would prevent such major damage next time the cable was yanked on, as
it simply slips off with little force.
