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.

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

om...
I bet most of the kids you used to teach had more intelligence than Aggy,
I feel quite sorry for him really.

There was a little lass called Ingrid. She was alarmingly and wonderfully
bright. I often wonder what became of her.

See my previous post. By the way, do you not know what 'RF' stands for? I

Radio Frequency. That's normally the original signal as received by the
aerial not a heterodyned signal.

No, if the LNB output is RF it is RF. The expression RF owes nothing to the
way the signal has been generated. Suppose I were to amplify and transmit
the output from an LNB. Would you say that the signal in the air wasn't RF?

2. My DAB tuner has an F type socket. Does that mean I have to feed it
with a satellite signal?


My DAB midi-system has the same. It also has a telescopic rod aerial
with a male F-Type at one end. I could probably flog that on ebay as a
set top aerial for a Sky box. ;-)

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.

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.

For a microsecond or so I thought I was reading the first line of a
Limerick. Nothing springs to mind that would neatly follow it but
somehow the thought won't go away...

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.

Oh come on, stop the obfuscation and answer the bloody question!

No, it doesn't scan.

You're right. Few things worse than a non-scanning limerick.

"There once was a lassie called Ingrid ..." will work.

Whose doing the second line?
