The symbol shows the location of the Winter Hill (Bolton, England) transmitter which serves 2,690,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Winter Hill (Bolton, England) mast?

D Hardy: You won't be able to diplex Moel-y-Parc and Romiley because the broadcast channels used don't allow. You could diplex MYP with Ladder Hill, if you can receive a good enough signal from it.
For more information on diplexing see:
Television Aerial Boosters / Amplifiers, Splitters, Diplexers & Triplexers
The three MYP COM channels are 48, 51 and 52. Romiley uses 41, 44 and 47. Ladder Hill uses 23, 26 and 29.
Diplexers generally split at 36, 38 or 51.
I can't advise on particular models as I'm not an aerial installer. However, ATV Sheffield provides a wealth of information and has an online shop. I know they sell Blake stuff and Vision stuff. Televes, Triax and Antiference are three other names that spring to mind.
I've come across these "overlap blocking filters" from Blake:
Overlap Blocking Filter from Blake UK
However, I'm not sure any will be of use to you. Whilst there is one that passes 48 to 62, there isn't one that passes 21 to 47. The filters will slope off so 48 is likely to be reduced a bit. The same effect is true of diplexers on channels adjacent to the split. I suspect that even if you could get filters with these passbands that 47 and 48 would not be useable because of the slope-off and the edge of the band.
There are notch filters available, but these are expensive. I know Televes do them, but you're talking over £20 for one which only does two channels.
Moel-y-Parc is due to have two new HD multiplexes soon, and these will be on 32 and 34. If you can pick them up where you are then, having diplexed a Ladder Hill aerial, you'll have filtered them out. What you're really looking for are two blocking filters 21 to 30 and 31 to 52 (or higher) so as to make your own diplexer.
One word of warning: In five years' time it could all change again. The two quasi-national HD muxes I mentioned - which use 31 to 37 exclusively - have been granted licences which could be revoked in 2018. This is because the 700MHz band (roughly 49 to 60) could be sold off for mobile services (5G maybe). This would obviously mean that transmitters on those channels will have to move downwards and probably those on lower channels shuffle down as well. There have been suggestions that the three COM multiplexes could become single frequency networks on channels in the 20s.
If this were to happen and you had diplexed a MYP aerial with a Ladder Hill one (with a 36 or 38 diplexer) then you would have to change it. Providing that Romiley was still Group B and on channels that your diplexer allowed, then you could simply switch your Ladder Hill aerial to face MYP and the MYP one to face Romiley.
With this in mind, I suggest that you get a Group A aerial that would be suitable for reception from MYP. Wideband yagis are a compromise and on Group A channels aren't as good as higher up the band:
Aerials, TV Aerial and Digital Aerial
The Group A aerial would be suitable for Ladder Hill now, whilst being suitable for MYP if it used Group A channels.
Alternatively, you could have a MYP aerial and Romiley aerial and keep them separate. You might use MYP as your main transmitter and switch to Romiley for regional programming. This would require a separate set-top box receiver. If you distribute the signals to different rooms you would require two distribution systems in order to have regional programming in each room (and of course you would need a set-top box in each room).

Thank you for your advice I'm very grateful for the time you've taken.
Need to think about all you've said but must admit some of it has gone right over my head!
I do have separate aerials for Romiley and the w/band high gain aerial I mentioned earlier so I can already use both but have to change the aerial lead of course.
Lots to think about!!
Thank you for all your help.

D Hardy:
It is always a problem to bring the signals from 2 different aerials together without causing serious problems.
One possible method to consider is to use a shielded coaxial switch with 2 inputs and 1 output. The downlead from one aerial is fed to one input and the other downlead fed to the second input. You can the select which transmitter service you want to watch by manually 'flipping' the switch. I have successfully used that method to receive signals from Mendip and Oxford (they offer different 'local' news, etc). I have to stress that you should buy a good quality shielded switch designed specifically for UHF TV signal reception. The inputs and output may be either a 'standard' IEC coaxial socket or an 'F-connector' as is commonly used for satellite cables.

Thanks for your comments.
Last night I decided I would connect both aerial leads to a cheap plastic y shaped aerial connector I've had for years and never used. I assume it's designed to split a signal but I've reversed that.
Then I have plugged the Y connector directly into my Freeview PVR but not re-tuned it leaving it tuned to the Romiley transmitter.
Then simply connected the PVR to the TV in the normal way. Then re-tuned the TV only whilst it is receiving a signal from both aerials.
Afterwards I checked whether BBC 1, 2 and ITV were north West and they were and being received from the Romiley transmitter most of the rest including Yesterday and the other channels I couldn't previously receive are
coming from MYP transmitter.
The PVR is only tuned to Romiley and that's all it's picking up the TV however is picking up both.
Slightly concerned by your comment about serious problems perhaps you could expand on that?

D Hardy: Using the splitter as a combiner is, by far, the cheapest and most straightforward possible solution. It isn't forced to work, but worth a try, particularly as there's no other straightforward solution.
The point is that the best practice way to combine two feeds is to have them filtered, which is how a diplexer works.
With your combiner, when receiving from Moel y Parc the Romiley aerial is connected and vice versa. Ideally, the one you don't want should be filtered out.

Hi, Dave
The set up is working OK since I combined the two aerials into one feed to the PVR/TV
Unfortunately the PVR doesn't allow me to sort the channels which is a a pity.
As has been suggested a switch might be the ultimate solution but for now it's working OK.
Cheers.

D Hardy:
The problems referred to are what happens when signals from different sources but are on the same or adjacent channels are combined together. A combiner is capable to doing that well enough if the channels are well enough separated. If there are two transmitters using the same channel (co-channel) they can cancel each other out, meaning no signal from either source. If they are using channels next to each other, such as 21 and 22, then there can be cross interference between them with can give either no signal, intermittently no signal, no signal on one source (or the other, but unpredictable), etc.
The fact that this happens can give rise to confusion and result in constant re-tuning when that is usually not necessary and can lead to no signals and severe frustration.
Such is the way with physics.

I have no BBC signal at all tonight in Stalybridge. It hss been difficult / intermittent for some months and needing frequent retuning, but now the freeview tuners on two different tvs don't see those channels at all. What can I do about this. Cheers, Paul

Paul Cooper: Apostcode would be helpful, so we could see what sort of signal you should get. Looking at someone elses postocde from that area, you should be ok for winter hill - check your comon cables, etc, since its likely you've got a fault with your aerial or connections.

Paul Cooper: thankyou, the postcode is SK15 1LZ. I do have an amplifying multiway adaptor with the main tv being direct off the aerial, but none of the tvs will tune BBC channels. All other channels are good.
