Looking at the currently used channels in your area and those predicted for use in the foreseeable future, I would suggest trying setting your Sky box' RF output to channel 34 and then tuning your TV to that (it would avoid any potential interference with other signals). However, it would be better to use an HDMI lead, if your TV and Sky box have that faciltity. If they dont, then could you use a SCART lead, the one that uses 21 pins to feed the signals. That way, you don't need to use the RF output and would get a better quality of picture and sound. If you can use the HDMI lead, then you could even watch the HD versions if your TV set is capable of showing them. A Freeview HD equiped TV set would be able to show them - the HD images are substantially clearer than SD.

Thank yiou for confirming a good result. It supports what many of us contributors have long been saying that you can have too much signal and that is a common cause of people's reception problems.
Glad it's all working satisfactorily now.

Glad you got some service. However, Channel 68 is very likely to suffer from interference later as it is in the range used now and in the future for 4G and maybe 5G mobile serices, so it is best to avoid anything above channel 60. It is also wise to avoid any of the channels used by transmitters whose signals may reach your location. That is why I suggested using channel 34 as none of the transmitters in your area use that channel.
As I stated, it is better to use an HDMI lead if at all possible, else use a SCART lead if the TV and Sky box do not have HDMI sockets.

Please recheck all the cables and 'F' connectors at both ends on the TVs not getting signals. Remember to look for strands of the outer sheathing touching the inner core and ensure that the electrical connections of the inner and outer are complete and without any open or short circuits. If all is well, try swapping two of the connectors feeding a working TV with those feeding a non-working TV - I know that means accessing the LNB directly so do be very careful. If that swap results in a formerly non-working TV getting good results then that suggests the LNB has a fault. If it does not get results then the two TVs may have problems. so check they are set up correctly still.

No subscription is required for use of Freeview or Freesat. What is required is a Broadcast Receiving Licence - which is NOT a subscription.
That licence allows reception and viewing of all 'live' broadcasts as well as whatever is available on the iPlayer. If a combined 'catch-up' service is made available it may also need a licence to use.
The issue of broadcasting rights is a matter for commercial negotiation, as is the availab lility of non-PSB services.

Put your full post code into the Digital UK website at Digital UK - Coverage checker amd that will show you the available transmitters in that area. It will also tell you the channel numbers to tune to. If you then go to Digital UK | Channel listings and find that transmitter, it will tell you what programmes are available from it.

But still many people do not get to use mobile phones at home because of poor signal coverage away from towns. Many rural communities only get very slow broadband, often too slow for streaming SD programmes, let alone get HD or UHD. Even in some urban areas the mobile signal is so poor it is hard or impossible to use. Where I live, on the edge of a county town, a mobile is unusable except in one room upstairs! Such is the lack of good signal coverage by the mobile providers.
Further, many people prefer to use a 'traditional' phone service rather than a mobile and BT are planning to continue providing such a service, but using VoIP rather than copper/aluminium wires as at present.
It is always the case that some pundits predict things will happen, but they are always over optimistic with whether it is viable or with the timing.

COM 7 and 8 are temporary services on 30 main transmitters only. There are no plans to extend the coverage at present. However, future changes to the transmission scheme will probably see the services carried on COM 7 and COM 8 being included in other multiplexes as they are changed from DVB-T encoding into DVB-T2 coding, which can carry more information but requires a TV capable of both receiving these transmissions and displaying them in HD when provided.

Alexa:
The change happened before June 2018 and was widely reported in the media in that area. Up until the change, a Group A aerial was correct. As COM 7 and COM 8 are now on channels 55 and 56 respectively, a Group A aerial will not give satisfactory reception of those, so a wideband aerial is now required. A Group A aerial is fine for channels 21 to 35 but not above that.
If you go to Digital UK - Coverage checker and put in your full post code and house number, you will be shown the current arrangements as well as the future plans for further changes. If you have a wideband aerial fitted now it will be suitabkle for all changes foreseen in the future.

Look at https://ukfree.tv/transmi…DAB, that is the DAB transmitters page on this website.
