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!

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 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!) ;-)

How many freeview channels are there?


40-ish TV, and a couple of dozen radio channels. The ITV and C4-related
ones are usually the most susceptible to reception problems, due to the
details of the way they are digitised. With any aerial, the main thing is
to make sure it is pointed as accurately as possible towards the
transmitter, and set level along its length. Also, if in a loft, it should
preferably not be trying to "look" through a solid wall or a water tank.

Never, because I always solder. But, I've come across a number of
installations where poor reception was caused by this.

I really don't understand why you seem to be attacking me about my
english

Some people get off on it.

Are you one of these?or am I refreshingly talking to someone else?

I'm definitely someone else, in fact my missus sometimes says I'm something
else. "Bloody hell, you're something else you are!"

I can see both sides of the graet literacy debate. I've always said that we
should think carefully before mentioning another writer's standard of
literacy, because I have known people appear on this newsgroup who have (as
it has turned out) overcome great difficulties to send their query. I'm
thinking about people who have real literacy problems caused by things
outside their control.

But everyone should write as clearly as they possibly can, because not to do
so is simple bad manners. It inconveniences the reader unneccessarily. And
from a pragmatic point of view, it alienates some people, so you are less
likely to get a helpful reply.

Your original post was probably the worst kind of all, because you used a
sub-literate style as an affectation. It was as if you'd addressed an
audience in a strange foreign accent that was hard to understand, when in
fact you were capable of normal speech. You can't tell me that it was
because you were in a hurry because a literate person can write decent
English virtually as fast as sloppy English.

The are a lot of middle-aged and elderly people in this group, and one of
their preoccupations is 'the declining standard of literacy in the
country' -- real or imagined. So you were in their sights straight away and
you got both barrels! Some people have a strange affection for the English
language and get quite angry when people abuse it.

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

Strange as it might seem, the full explanation is long and arcane to the
point of stultification, but if you think about it, the cable is carrying
electricity like any other cable. (The only difference is that the
electricity is varying very rapidly in strength and the TV signal is
described by these variations). Now as you probably know, electricity likes
to find the easiest path, so if the inner core and the outer braid touch it
will take the path thus provided, as a sort of short cut. This means, of
course, that it won't need to go any further down the cable, so it won't get
to the TV set at the end of it.

The explanation I've given you will annoy some members of this group, who
will feel that I have simplied to the point of inaccuracy, but I too was
once a teacher and I know that knowledge has to come in bite-sized chunks!

Alas Charles, this is a council of perfection. We live in the world of
quick, cheap, easy, and short-lived.

The effects are more obvious when the cable is carrying DC.

We usually crimp the inner pin twice using 'special' blunt cutters. Never
have any problems. We solder sometimes, usually where a plug is likely to be
re-inserted many times.

Seems to be a bit of an echo around here tonight. Dare I mention
F-connectors? They must be real buggers to solder, but maybe the
perfectionist should tin the inner wire, just in case?

Actually the comments made to me were after I had "badly typed" what
the problem was that I was encountering. As I keep mentioning I wasn't
aware that I had to be
so grammatically precise when asking for help. Please accept my
apologies for offending you and/or anyone else here in this group. I
never intended this all to be an issue.

Grammar isn't much of an issue here, but technical precision is, because
it has to be. When you're dealing with technology you'll find that the
laws of physics are more pedantic than any of us. Choose the wrong piece
of gubbins, connect it wrongly or set it up wrongly and it simply won't
work, and unless you can describe the problem clearly, nobody will be
able to tell you why. Clear English helps the understanding of anything,
but it's more important than ever when dealing with a subject that many
find difficult to understand in the first place.

Although bad English annoys me, I rarely take people to task for it on
usenet unless it is in some way relevant to the subject. Writing
something semi-literate and full of mistakes and then stating that you
actually had qualifications in the subject was, however, a bit like a
red rag guaranteed to have most of us pawing the ground ready to charge.

Nobody's really cross though. It's all in fun.

Hello Dave. First and foremost many thanks on your advice and help. I
do appreciate the fact you have refrained from pointing out any
grammatical errors I have made. If I do ever use the computer to
type,obviously I take time to plan and set out the content. Otherwise
i use it for research. I have a few close pals with instant message
accounts and I can only explain my poor literacy skills as sheer
laziness. When you spend all day having to be 150% correct, it's nice
to be able to just Waffle" as it were, and not worry.
Anyhow, thankyou once again, I am just off up into the
loft to try this new aerial out. To all others reading this ....Do not
worry, If it works, I need not come here to tell you. Deal??? Regards

hi zoe
yeah i knew instant messaging style when i saw it
i use internet relay chat which is the same sorta thing
and there i use all lower case for speed
and newlines instead of punctuation

But, as you've found out, Internet forums are a bit different. This
particular newsgroup system is called Usenet, and has been running since
1979. (Google-groups is just one of many gateways to it, by the way.)

You've run into this thing called "netiquette", which has grown up
mostly here in Usenet, which is a bunch of informal rules to let us get
on with each other reasonably OK. You can search on that term, if you
want. Part of that happens to be an expectation that people take a
little time to compose a coherent and punctuated message, although a
colloquial style is OK.

Anyway, despite the fuss, you're getting to the answers that you want,
so you should get the telly sorted out eventually. And as others here
have said, please do tell us if you do get it working, so that we know
that we've not been wasting our time.
