Cable length

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Roy Cook"
saying something like:

However, a search
has found a spot where we might be able to 'see' the satellite. This
location is about 30 metres from the receiver. Has anybody got an opinion as
to if this length of cable is workable and what would be the best type to
use?

Sure thing. My Sky dish is at least 30M from the receiver. You can
always use an in-line amp if necessary.

A friend on mine has asked me to try and install a sky dish in his house
which has a large number of tall trees to the south. A Sky installer said
that it was not possible to get reception and walked away. However, a
search has found a spot where we might be able to 'see' the satellite.

What exactly do you mean by "...we might be able to 'see' the satellite"?
Do you mean that there is a gap in the trees? If so, beware - trees grow up
and across. What might be possible now may not be true in a couple of
years' time.

The man from Sky wants to be back and off in his van so that he can make
a wonderfull eight installs in a day.

There should be no problem with this sort of length. Make sure you use
real CT100 or preferably WF100 foam cored as it is more imune to water
ingress (although you should be making sure water can't get in it
anyway).
I have one customer running about 80M which works fine straight from
the LNB but LNB outputs do vary.
A dish one size up is a good idea as well.
You can use in-line amps for more length if required but dont overdo
it.
It is better to move even further away for a definite line of sight
rather than risk trees growing in the way
I prefer to do this sort of thing in the middle of summer when trees
are in full leaf, just to be sure.

I prefer to use the extra tough green buryable cable if it is to be
exposed over any long distance or certainly if it is to be buried but
it is about twice the price

As always I endorse all of Mr Widgett's sage advice. He certainly
knows his onions.

There should certainly be no problem with a 30m run. Most LNB outputs
are 25 to 30dB above receiver threshold. You wouldn't want to use all
that margin, but 30m of decent cable will only use about 10dB of it.
If you use ordinary cable (as opposed to 'direct burial' types), it
must not go anywhere where it is permanently damp. Remember that trees
move around in the wind so if you find the transition area between
'screened' and 'not screened' put the dish well away from it.

How many times have I heard the disconsolate wail "The Sky man says we
can't have Sky because of the trees!" On further questioning it often
turns out that the Sky man has also said that although reception is
definitely impossible a local installer might be able to do it. Just
as the religious believe that God is good but God is omninipotent and
therefore was responsible for your child getting cancer, the Sky man
is capable of an extraordinary 'double think'. He says one thing which
is the official line, and another which is the truth as he sees it.
But then again, don't we all? The hypocrisy of modern political
correctness can only be resolved for those in sensitive offices by the
adoption of twin moralities.Like a double line power inserter, there
has to be absolutely no crosstalk between the two channels or ugly
conflicts will arise. So in the office our man will blather all the
modern bull****, whilst in the company of trusted friends he will talk
like a normal person. If what he said in the office were to leak into
his private circle he would be held up to ridicule; if what he said in
his private circle was to leak into the office he would be dismissed.
We are in this respect no better than the Nazi or Soviet states. Have
I digressed, would you say? "A little!" is I hope your tactful reply.

It's rather appropriate that you signed that twice ;-)

Because it was twice as clever as normal? Actually, I'll let you into
a secret. I had been drinking.

The gap is below branch height between two trees. Behind them is clear sky
with no obstructions so I'm hopeful. The plan is to try out the location
with a second hand dish and LNB. If this shows some sign of success then
new equipment with (as advised) a larger that normal dish will be installed.
Once again can I thank you all for your helpful replies. After 35 years as a
TV Tech I gave it all up a good few years ago and now find that I am a bit
rusty so your recommendations have been welcome.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember J G Miller saying
something like:

Loose talk can cost lives.

longer exists I bet there isn't even a mucky envelope nailed to the
gate post to mark it's passing.

You are correct, there isn't. Now let out as office space. I
understand that the local council are about to lease space there.

If you tell me what you would like writing on the envelope I'll walk
around there and fix it to the gate.

I remember a few years back lowering some of the 2m dishes off the roof
into the rear yard on a rope while trying not to knock the rather large
lettering off the wall!!!!!!!! Made it with a couple of heart stopping
moments

Hi Graham
I was at GTVR Bradford from '71. I left in '82 to start my own business which lasted for about 8 years. After that I joined the
Civil Service and went work as a Radio +TV instructor at our local Skill Centre. That lasted until 1995 when I was made redundant
(Thanks Maggie). Upon re-joining the real world I was surprised to find that wages had gone down and I was out of touch with the
new stuff so I went to work for a former GTVR colleague as a pawn broker. I have fond memories of my time at Granada. I'm of the
opinion that the 70's and 80's were a 'golden' age for us TV Tech's. The TV's weren't too complicated (apart from the Philips
sets) and you knew that when you took the back off a set - even a Finlandia - you were in with a good chance of getting it
working. I've just bought a 37" all singing and dancing LCD TV and I can guarantee that if it should develop a fault after the
warranty runs out it will be straight in the bin!!
When I handed my notice in I was given a Termination interview and I remember telling the regional manager that if the company
didn't get its collective finger out all that would be left of GTVR would be a plaque on the wall at Bedford HO. Now that the
company that we knew no longer exists I bet there isn't even a mucky envelope nailed to the gate post to mark it's passing.
I retired just before my 60th birthday and haven't regretted it at all. I'd stopped doing any form of electronic servicing a few
years before when I discovered that it wasn't fun anymore. Occasionally I get asked for help and advice by friends and this is why
I'm going to attempt to get satellite reception through a 10'x10' gap between two trees. I don't mind doing this sort of thing now
and again, it's a bit different and helps to keep the grey matter active.

Cheers for now
Roy

What was wrong with the Phillips series?, you got a particular chassis
in mind?...

Cant remember the chassis but the switch mode power supplies used in the
late 80s were a pig on the Philips.
