Sat dish distro Q

I am a lurker, never posted on here before, but gleaned some great info thus
far, but my knowledge of Satellite systems is pretty limited.

I have a largish listed tenanted house- the new tenants wish to have Sky+ in
at least 3 of the rooms. Being that it's listed and we cannot have a Sky man
roll up and graffii the exterior in garlands of cable hither & thither
drilling window frames as he goes.

Previous tenants had Sky+ in just the living room, and thus currently there
is a dish mounted to a growing post [1] approx 20m from the property in the
garden and the 2 CT100 cables run in a conduit under the lawn into the
cellar, and thence straight up into the living room. Cabling internally to
the various rooms is pretty easy and there is some coax already present in
some rooms from a previous re-wire.

What would be the best solution to implement the above as far as allowing
several receivers to share the dish?? For obvious reasons, running more
cables to the dish isnt really possible!!

TIA Tim..

Welcome to our happy little band, Tim!

You really need to get four cables from the dish to the cellar. That
shouldn't be a problem if there's a conduit in place. If the conduit is
too small for four CT100 cables you might be able to get two CT60
shotgun cables though it (as a last resort). You will need to replace
the LNB on the dish with one that has four fixed outputs (a quattro as
opposed to quad LNB). Normal practice is to replace the dish if the LNB
needs to be replaced. The four feeds go to a multiswitch in the cellar.
The multiswitch can have as many outputs as you want. I suggest you get
a multiswitch with some spare outputs, just in case.

But do the tenants really want three separate Sky boxes? Would they not
be happy with one box and the ability to control it from all the rooms?

Thank you bill!

I will look at the conduit size and see if 2 more cables can be got up it- I
guess lifting the turf, removing abit of soil and replacing existing conduit
with some 32mm waste pipe or similar to facillitate 4 cables could be done.

The tenants have asked if feeds for separate boxes can be provided,
obviously we dont have to comply, but would rather reach a good middle
ground that will prevent poor / ugly cabling which might appear, and its
then a job done for the future.

If you connect an aerial into the multiswitch the signals from it will
be available at all outlets.

Q: If you add a terrestrial signal to a Multiswitch which presumably
'combines' it and then is cabled to a Receiver location- how do you
'extract' the terrestrial analogue signal from one of the two Sat feed
cables to the receiver?

The wallplate includes a diplexer on one of the feeds.

You need a "splitter". I have two waiting to be installed - some time.
:-)

I think I bought them via Amazon although they seem to be out of stock
there at the moment.

Here is another source:
http://www.quasarelectronics.com/khx...ow/122821.html

It is labelled as a "Combiner" but as you can see from the arrows and
markings it will work in either direction. It can take a single combined
input from a multiswitch and split it into one satellite output and one
radio/TV output.

It's neater and better to use a diplexed outlet though.

Can you recommend a UHF TV - Satellite IF diplexer, with power-passing
to the satellite port?

As an aside, I've been considering communal systems, and wondered why
they don't use sat-IF amps and simply trunk all 4 signals into each
apartment, where each resident will then have a multi-switch and can add
as many outlets as he wants for no extra cost.

This would have the advantage that there's no need to run new cabling
back to the central multiswitch with all the associated costs when a new
sat point is required.

Obviously, the reason is up-front cost, because relatively few people
would use this facility.

But in might be a good system.
