Hi, I'm at the stage in the house restoration where I can wire for TV &
Sat. It's a 3 bed terrace and I'd like the following circuits.

Loft ariel to splitter 1, located under landing floorboards.
Landing to splitter 2, and then to lounge and office outlets.
Landing to splitter 3, and then to dining and kitchen outlets.

I've read that the use of splitters can weaken the signal so I may need
an aerial amp.
How are these connected?
Would one serve the whole circuit?

Satallite. Can this be split like TV cable? (I'd probably only want two
outlets for sat).

If I use twin VHF/UHF + sat sockets (eg page 185/quote 13740 of
Screwfix), can I connect the radio and TV simultaneously with a splitter?

Cable. Can I use screened coaxial for sat or do I need sat cable (they
look similar in the Screwfix catalogue)? Yes I'm on a tight budget.

Are there any fancy products where by TV and sat are combined in one cable?

Thank you very much,
Neil

Lots of useful info, all the kit available to buy for DIY, or they do
the job for you (but only local to them).

A friend has used these people twice and I intend to use them when I get
my extension built and need to route analogue and satellite around the
house.

Look at the range of amps by Televes at www.televes.es

Their range is sold in the UK by (amongst others) CPC at www.cpc.co.uk

They do a multi-input amp that permits separate inputs of TV, sat, DAB, and
FM radio with umpteen outputs. I have one of the 'lesser' types and am very
satisfied with it.

BTW the satellite isn't that simple to split and distribute. This is
because the sat LNB, assuming the ASTRA Sky system is sourced via four
states in the LNB that is High band, and Low band, and Vertical
polarised signals ,and Horizontal polarised signals so there are 4
differing modes, the SAT LNB that's the thing that's on the end of the
arm that sticks out from the SAT.

These receiving states are signalled from the receiver via differing
voltages and a superimposed tone signal so only One sat can control one
LNB use Two sat receivers and it won't go if they want different things
at the same time. Let alone the 18 odd volts to supply the LNB

The answer is to have a couple or more LNB's combined in the same unit
or even 4 known as a Quad LNB and run SEPARATE cables to each receiver.
For more outputs a specialist amplifier is needed that takes a Quad LNB
and does some very clever switching but these are rather specialist..

There are a lot of questions here Neil.

The method for distributing a VHF/UHF system is very different from
that required for satellite distribution.

It's probably easiest if I take each of them separately first and then
illustrate how you could combine.

VHF/UHF
========

It is reasonably easy and not expensive for a basic system to
distribute VHF/UHF to a lot of outlets using a central amplifier and
splitters as you describe.

First of all forget anything that you can buy in a DIY shed. It is
poor quality and consists of cheap signal boosters intended for
delivering signal of a sort to up to about 8 outlets in total.

You need to have a distribution amplifier with a high level signal
output which you then feed to the splitters as you suggest.

As an example, have a look at the Antiference A281 or A261

http://www.antiference.co.uk/ampadvice.htm

There is an illustration there on how to hook it up to take input from
VHF and UHF antennas and then to distribute via splitters.

Always use satellite grade CT100 cable for this. The TV coax sold by
various places is absolute garbage and will not give good signal
results and moreover be sensitive to interference. It is not worth
skimping. The components such as amplifier and some splitters should
cost no more than about £60 and then whatever it is for the wall plate
outlets.

If you wanted to combine VHF radio and UHF TV and have outlets for
both but fed with one cable you can do it, but the Screwfix products
aren't it. You need a diplexer to do this, which is a filter and two
outlets. Basically the VHF signals go one way and UHF the other.
These cost £6-7 such as Maplin YB54J

A system like this will not take account of differing signal levels
between channels, nor will it improve a poor signal. Before starting
make sure that you have good, clean signals.

If you have signals for different channels that are not equal (usually
this is the case) you may get too much signal on some channels
(leading to overloading with patterning on pictures etc. or not
enough, leading to grainy pictures. It is possible to correct this
but it does cost money. You can get filters matched to your channels
and adjust them individually. These are normally about £50 a channel
and it really needs test gear to set them up (i.e. professional job.

You can get really good results but it does depend on what you are
willing to spend.

Satellite
======

Most of the satellites with a footprint including the UK operate on a
range of frequencies known as Ku band. This includes the Astra 2
constellation, operated by SES and used by BskyB.

Unlike UHF TV, the first part of the receiver, is actually in the LNB
(the device sitting in front of the dish. Because of the way the
technology works, the receiver has to send power to the LNB and also
some control signals to select between two frequency ranges and
vertical and horizontal polarization. The satellite is transmitting
on frequencies from about 10 - 13 GHz, whereas the cable carries
signals in the range from about 900 MHz to about 2000MHz (2GHz).

This means that for a simple system, there is a one to one
relationship between receiver and LNB. You can't just put the signal
through a splitter - it won't work.

If you want to have up to four receiver outlets you can do it by
replacing the LNB with a Quad (not Quattro) type. You home run
cables from the LNB to up to four satellite receiver outlets - it
does not go through the UHF distribution system.

In effect the LNB now consists of four logical LNBs in one box. Each
receiver can select a different frequency/polarisation independently
of the others.

For outlets you would really need to have a diplexer filter fo rUHF
and VHF and a separate connector fo rthe satellite. I am not sure
that these are made. Alternatively you would use two plates.

More than 4 satellite outlets and
==========================
Combined Satellite and UHF/VHF distribution.
====================================


To achieve more than four satellite outlets, a switching device called
a multiswitch is used.

Instead of a Quad LNB, a Quattro type is used. This has four
outlets, with each representing one of the polarisation and frequency
options. It is connected to the multiswitch with four cables. You
then home run a cable to each outlet. The receiver sends its
control signals in the usual way but instead of them going to the LNB,
the multiswitch interprets them and connects through the appropriate
signal out of the four. Each receiver thinks that it has exclusive
LNB access.

Moreover, it is possible to combine in VHF and UHF signals and deliver
them down the same cable. The wall outlet can then be a triplexer -
e.g. Maplin L72AN.

These types of system are used in multiple occupancy dwellings to
avoid large numbers of satellite dishes and are expandable up to
several tens of outlets.

A multiswitch costs from about £15 to £25 per outlet, plus the outlet
plate.

for example

http://www.spaun.de/html/sms_5802_nf.html

or

http://www.spaun.de/html/sms_9941_nf.html

for a switch able to allow selection between two LNBs and access to
two satellites at the same time.

You can work out from this that to get something able to distribute
satellite and UHF/VHF to a fair number of outlets, you will need to
spend around £500

So the LNB is the bit that sticksout on the SAT, but what does LNB stand for

So the Low Noise Block sticks out on the SAT ?

Low Noise Block

It's actually a shortened version of the complete description, which
is Low Noise Block Convertor.

So it's called a block convertor because it converts a block of
frequencies to a lower range.

In the case of Ku band it is . 10.7GHz - 11.7GHz and 11.7GHz to
12.75GHz - i.e. two bands.

These are converted down to a range of 950 to 1950MHz for the lower
band and 1100 to 2150MHz for the higher.

The reason for doing this is that the signal level as received at the
dish is tiny. Even with some of the powerful new birds such as the
Astra 2 constellation with power levels of around 100W per
transponder, it is still small.

http://www.astra.lu/corporate/satell...et/index.shtml

Imagine looking at a light bulb at 20-odd thousand miles away and you
can see the point......

Signals at the satellite transmission frequencies would not survive
being sent through CT100 type cable, so having the first stage
electronics out on the dish means that they can be amplified and
down-converted to a range more suitable for the cable.

It's important that as little noise is added to the signal as
possible, so great care is needed in the LNB design and hence the
term, "Low noise". Considering all that, these things are
remarkably cheap, at least at the consumer market level.
