jane: You can use the old Sky box provided your dish has a spare output stub on it, and the fact of you using Sky+ could mean that it might have as the engineer that installed the dish may have fitted a quad block onto the arm rather than a dual version, the cost of the former only being fractionally more than the latter.
Although its not always that easy to see as the connection plugs are slightly shrouded, but have a look at where the cables go into the LNB to see if there is any spare outlets, if there is then it requires a cable to be run from it to your Sky box.
Should of course there not be then the LNB requires changing to a quad type, these being roughly under £10.00 from numerous e-bay outlets and is a simple job to change over, nothing really complicated.

Sam: If your Freeview box is connected to your TV via a scart lead, then all you do is run a co-ax cable from the living room Sky boxes RF2 output into the conservatory and fit the magic eye to the end of the co-ax cable, the other end of the magic eye going into the conservatory TV's aerial socket.
If your conservatory TV is dual standard it has to be set on analogue, then you carry out a scan to pick up the Sky boxes RF output channel.
In use, you simply use the TV's A/V button to switch between the Freeview box and the normal TV, which will be the analogue signal from the Sky box, the magic eye switching channels as required.
You will also have to go into the Sky boxes engineers menu to make sure that the Sky boxes RF2 power is on, this done by pressing services then "4 - 0 - 1 - select" the latter done in a smooth operation without uneven gaps, this best achieved by NOT looking at the TV whilst doing it.
Should have any variations to your assumed connections, the instructions can be altered to suit.

Peter: Your TV cannot respond to 8K transmission mode signals, so you will have to use a Freeview or Freesat box with it, this in effect turning the TV into a monitor.

Louise: Your location, which you havent mentioned, could be a possible cause of the problem "if" you are receiving too strong a signal, as an over powerful signal can block the channels (or channels) from being received.
Just because it worked on another TV can simply be because that TV is not quite so sensitive, and as such can cope with a higher input signal.
People in high signal areas can get over the problem by using a simple attenuator in line with the aerial socket, needless to say having prior tried disconnecting any boosters that they may have before purchasing the attenuator.

Neil: In your 3.48pm posting you mentioned about two TV's connected together using the one aerial, then you later mention digi boxes tuning etc, could you clarify whether or not the TV's are Freeview devices? or is it that you have two Freeview receivers off the one aerial feeding two TV's?
I ask this because a possible reason for what you are experiencing (as mentioned @ 3.48pm) could be connected with your location as well as dependant on your aerial set up, as using two TV's (or boxes) on the one aerial without using a two-way powered splitter "does" drag the signal strength down, as it unbalances the load matching between the TV input and the aerial, that is as well as the fact that something shared two ways means each getting less. (whether it be RF or anything else!)
Any signal being received that's a little too strong can cause the receivers tuner to become desensitized, or if really too strong block it altogether resulting in the warning on "no signal received".
If the former is applying, (desensitizing) then the two TV's being connected to one aerial will pull the signal down a little thereby allowing the tuners in each TV to operate better, whereby they can "indicate" (but only indicate!) a higher signal level, but if a lead is disconnected from one of the two TV's this will allow the already high powered signal on the other set to increase further, this causing its tuner to struggle even more to keep stable with the result of the a reduced signal / quality level being indicated.
You have to appreciate that the signal strength indicators can be fooled by an over strong signal, and in many cases can indicate lower when the signal received is actually getting stronger and is near to cutting the box out, this is something that only applies to digital receivers and not in the case of analogue.
Not saying that this is definitely applying in your case, but it could (and does) with some other installations.

Lesley Knight: That could possibly indicate that you are picking up Keighley Town's lower multiplex channel numbers rather than the main Keighley station on the much higher channels.
Try manually tuning in Mux Ch58, that being ITV1 from Keighley, or alternatively remove the aerial and carry out a scan without it, this blanking out the channels stored memory, then "before" reconnecting again carry out another auto-scan whilst "at the same time" viewing the channel numbers rising in the progress bar, then as soon at it reaches Ch53 immediately plug the aerial back in again and that will allow Keighley to load.
This said taking it that you are receiving from Keighley, as Emley Moor is also forecast as possible, and should it be this station still use the aforementioned procedure but reinsert the aerial at about Mux Ch38, although no need for the same speed of operation as with Keighley.

Jean Reynolds: Unfortunately its not easy to assist when the location of your sister is not known, (post code preferred) as her reception possibilities including the transmitter channel numbers of the station she is tuned to cannot be checked on with knowing this.

Peter Darrigan: It would appear that you have picked up Moel-Y-Parc on Mux Ch45 rather than Winter Hill on Mux Ch62.
To avoid having to manually tune in the channels take the aerial out and re-scan without it, this to blank out the stored channels, then before re-connecting the aerial carry out an auto-tune whilst viewing the channels rising in the progress bar, and as soon as you see it getting to Ch53 re-insert the aerial and that will allow Winter Hill to load.

Martin: Although its not impossible for a problem to be presently in existence at the transmitter, are you positive that the devices mentioned are actually capable of HD reception? that meaning they are equipped with DVB-T2 tuners.
What model of Humax box are you referring to?

richard: Well, Poole is only a Freeview light transmitter with limited channels being available whereas Rowridge is a full service station, however the problem is that good reception is (or will be) guaranteed on the limited number of channels from Poole, but Rowridge is only forecast to provide about the same, as even although its a full service station the lesser Mux channels SDN/ArqA/ArqB are forecast as poor, ArqA/ArqB presently indicating as variable.
As predictors are never really 100% accurate because they cannot fully cater for local conditions, I would be inclined to leave the aerial as it is, as come changeover if Rowridge proves a no go then at least you have given it a try.
