Which is the best website / diagram with simple instructions for
crimping a UHF lead? A relative has just had a new aerial and wiring
installed and they left the fly lead sliced off flat. Trying to advise
them over the phone is not easy.

TIA

Umm, one wonders what sort of job it was to leave the cable unterminated. I
wonder how they demostrated the picture quality to your relative?

Interesting. I've had trouble with the crimp effectively collapsing and
then the teeth fail to grip the cable. I've solved this by taking the wire
braid, twisting it together and then wrapping it around the cable before
fitting the crimp. The braid is then held tightly against the crimp and
also stops it collapsing.

Firstly, you need to make sure you wrap in the direction of the thread
otherwise there is the possibility that the braid "underdoes" as you screw
the end cap on. Secondly, I do wonder whether the megalithia method gives a
better connection for the outer braid.

I'll have to try the megalithia method next time I'm making a cable.

I think I know what you mean. I've never had any problems with what
you mention, nor have I ever gone the solder way. It's the best
documented process i've seen on the interweb so thought i'd proffer it
up to the OP.
Might give it a go too.

I've used the "bend the pin" method successfully in the past but then my
cables "stay put" for long periods. The solder method is actually very easy
providing you remember to just use as little heat as you can get away with.
Cored solder wicks quite nicely into the pin.

Interesting, and pretty close to what I've gradually evolved
empirically over the years when I couldn't avoid having to fit one of
these wretched things. Even more interesting is that despite the dire
warnings about brown TV co-ax, the example of it shown looks almost
exactly what was installed in my home about 15 years ago for TV and FM
aerials, the TV one is looped without any additional amplification via
three DTTV receivers, and they all work just fine on all channels.

Brown is just a colour - it's what's inside the sheath that matters. Look
at all the wire screening AND the full copper foil screen. In comparison,
"low loss" has so little screening you can literally see through the
screening.

BTW, each DTTV receiver in the chain is almost certainly amplifying before
splitting the signal into "used internally" & "passed along the chain".

I disagree with using 'as little' heat as you can get away with. You
should use 'as much' heat as you can get away with (but as quickly as
possible).
