With all due respect I have no idea which are the correct ways to
signify technical words simply because I have not needed to. For the
immediate future I will endeavor to learn some "Technical Jargon" to
keep you all off my back.

You don't necessarily need to use technical words. You do, however, need
to be accurate in your description of problems when you use layman's terms.
We might then understand your problem.

Can I ask, What is the significance in the wire mesh around the coax
being kept away from the inner wire?

If the mesh touches the centre wire, the signal is short-circuited,
and
never gets as far as the TV.

Thanks for that. I am currently putting new "grommets"? on a new coax
cable. Is that correct?

Grommets are rubber or plastic rings that are put around cables to
protect
them from damage where they pass through holes, especially sharp-edged
ones
in metal boxes etc. Do you really mean "grommets" or do you mean
connecting
plugs/sockets (as in improving a joint in the cable)?

Sorry was reading the wrong bit of my instructions. No I am putting
new plugs on

On re-reading that article, it is a bit over the top to solder the inner
connector, so I would not worry about doing that bit!

the electrical circuit between the aerial and receiver needs two conductors
(like any other circuit). If the inner and outer touch, then a "short
circuit" occurs at that point and any signal goes that way rather than
towards the receiver.

I'm sure your GCSE Science included simple circuits. The theory is the
same whether it is a battery feeding a lamp or a n aerial feeding a tv set.

If you are prepared to tolerate the signal deteriorating due to corrosion
building up on the copper conductor, then don't solder. To make a proper
joint, use solder.

I have an amplifier and power inserter and so confuse as to what goes
where

I know that is a counsel of perfection (provided you don't fry the plastic
bits), but have you ever really lost any signal that way? I haven't (and
I'm nearly as old as you!) ;-)
