i'm moving into a rented flat tommorow, the landlord dosent know owt about
the tv/phone/broadband options available, and i havent had time to ask
others in the block yet.

There's a sky minidish on the roof, it looks to have a quad lnb on it... 4
down leads come from it, above that is a FM antenna and a normal terestrial
antenna.

In the flat is a wall plate, it has a Tv antenna socket, radio socket, and 2
F type connectors,

one is lables 'SAT' the other 'RETURN'

Now i gather the sat one is connected to the lnb.... most likely through a
distribution amp as there's only one dish, and a good 20 or so flats it
apeers to feed.

it's the return F connector i can't work out, anyone any ideas wot it's
for??

i'm wondering that i either need some sort of box to go between the wall
plate sockets and the sky box, which connects to both F connectors,
or maybe the return is for satelite broadband which most likely isnt
present,

OR .. thought that just hit me, it could be the 2 F connectors are both sky
box connectors for a sky plus twin tuner jobbie, and the return label was
just what was on the wall plates the builders bought,

i may have answered my own question, but can someone confirm or deny it if
possible.

All of them watching exactly the same transponder frequency and the same
polarisation if that's how he's doing it.

You're satellite box should have an LNB IN and LNB OUT (so someone can watch
exactly the same thing your watching on another box). I presume LNB OUT is
what goes to return, though why you would need to connect it up I don't
know.

what he's saying is you are wrong.

i could have given an answer that started with 'your satellite box has a

Mine has LNB in, and RF1 and RF2 out. No LNB out.

For me, RF2 feeds a distribution amp to the rest of the house. This would go
to the "return" connection in your installation and give you all aerial
signals and 1 x Sky box output at the far end.

Nope. LNB IN and LNB OUT are completely different to RF in and RF out. The
former use satellite connectors and the latter used domestic aerial
connectors such as on a VCR. LNB OUT is for connecting another satellite box
to and the original poster stated that both sockets on the plate are of the
satellite variety.

Probably an extension wired through to the bedroom. Wire the RF OUT of
your Sky box to it, and you can tune your bedroom telly into whatever is
being watched on the Sky box.

Wrong. The OP has stated that 'SAT' and 'RETURN' are BOTH F TYPE CONNECTORS.
There are both satellite sockets NOT RF sockets.

Satellite signals are Microwave band DVB-S transponder signals heterodyned

DAB is digital radio! You need to feed it with a F type plug connected to a
radio aerial.

The return to the bedrooms is an 'f' type on some plates. You obviously
think that 'f' = sat and belling = terrestrial. Many terrestrial amps (all
the pro ones) use 'f' types, as do all screened splitters, taps, DC
blockers, equalisers, power inserters, etc.

I do wish you wouldn't spout such ill-informed twaddle.

Radio Frequency. That's normally the original signal as received by the

IF or Intermediate Frequency.

blimey, what have i started :)

There's only one wall plate for tv connections in this flat, in the living
room, and it has 2 x F connectors, and 2 x normal terrestrial type aerial
connectors as found on the back of every TV/vcr/sky box that has an RF
output to feed the TV.

I think i've figured out the flats have one of the communal single dish with
switches and amps systems sky offers, there is one that they install that
has the Tv and radio antennas, and uses a 4 outlet face plate, with 2 F type
sat connectors, and they say those 2 are seperate lnb feeds, for use with a
sky plus box, next to the face plate is a 2 socket phone jack, which sky say
must be placed there for their multi flat distribution system,

they also say the faceplates must be branded sky something or other, and the
one in my flat isnt branded anything, so it may be a generic jobbie that the
return label is not right, and should read sat 2 or something.

but i guess i'll find out tommorow, will take my sky box from my camper and
try it out, if she gets a signal, i just need to get a viewing card off sky
to get the system working.

My DAB midi-system has the same. It also has a telescopic rod aerial

If there's no other aerial outlet in the bedrooms or kitchen of the flat
then it may well be a (wrongly labelled) second LNB feed for Sky + or HD -
or it may not be connected to anything.

Unless you're using Sky multi-room, technically you don't need to plug the
box into the phone.

It would be illegal and you would be broadcasting on two new frequencies the
sum and the difference of the oscillator frequency and the RF frequency and
probably other harmonics as well depending on the filtering and linearity.
In electronics RF amplifiers amplify what is transmitted or received and IF
amplifiers amplify one of the heterodyne frequencies, usually the lower one.

For the sat to work properly there will need to be a quad or quattro LNB and
a multi-switch to allow any receiver to select any band and polarity e.g.
http://www.emp-centauri.cz

Proper satellite receivers (not $ky) loop the LNB through so that it can go
to another receiver or another room, alternatively you could daisy chain
your VCR, DTT, and DSAT UHF and run that through to another room (e.g.
bedroom). The return on the plate may go to an outlet elsewhere in the flat
(try the bedroom).
