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!

    From one of my tips files
    http://www.divdev.fsnet.co.uk/tips2.htm

    I am getting a bit tired of seeing TVs and VCRs where someone has tripped
    over
    the trailing lead to the aerial socket. The connection to the tuner is then
    broken in
    the process. Make up a simple adaptor of a small length of coax with plug on
    one end and socket on the other and plug the aerial lead into this. Not
    having the
    right-angle connection to the back of the set gives a chance for the lead to
    disconnect
    without damaging the tuner.

    You also have the option of making a loop or two of the short add-on lead,
    around a cable tie or similar, to anchor to a firm bit of chassis or casing

    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.

    Forgot to mention an alternative if you just cannot get it soldered is to
    use a panel mount connector (nuts on both front and back of connector).
    You'll have to obviously open up the shield case (if there is one) to get
    behind it, but if there's room in there, this is a good option.

    No there isn't a better way than solder.

    Even if you used a F81 or F61 connector and bolted it down to the
    tuner, the frame of the tuner would pull away, from the forces
    involved. Been there done that.

    Use a push on adapter, these suckers will pull right out and won't mess
    up the tuner connector.

    I've soldered RCA jacks to the tuner and used a RCA to F adapter, it
    pulls out too.

    F connector right angle adapters will take the force of the heavy
    cables off the connector.

    To solder to a tuner case you need a good non corrosive flux, works
    real well with low wattage irons. Sal-Met is the brand I have used. The
    resin(flux) in wire solder isn't good for soldering to cases like
    tuners.
