Rosemary: You need a conventional (terrestrial) television aerial. However, it is likely that you will not receive all Freeview channels as you are served by a transmitter which carries only Public Service channels, these being: BBC TV and radio, ITV, ITV+1, ITV2, Channel 4, Channel 4+1, E4, Film4, More4 and Channel 5. It also carries, but the LG model you have won't receive them.
For that reason a satellite receiver could be a better bet, particularly if you haven't got a terrestrial aerial. It would seem a waste having one installed if the limited channels available don't satisfy you.
Freesat is the free-to-air satellite equivalent of Freeview, although there are differences in what channels are available.

Christine: Judging by the fact that we have just changed from BST to GMT it would seem likely that that is the reason why.
If you have not experienced this before then that begs the question: what is different? Are you using a different receiver or is there a setting that is different?
Are you saying that even though the clock changed, as it should, all the timings changed?
What is the make and model of the recorder in question?

Rosemary: I second jb38's reply!
By paying £10.50 per month would, in effect, be renting the ability to record prrogrammes. Set at the side of what jb38 has highlighted, there would seem to be no contest.
To look at it another way, if you are paying over £30 per month now, the Freesat receiver will be roughly the same as four months' payments to Sky. And after that there are no other charges.

Christine: That does seem odd. And, of course, what was 21:00 is now 20:00, yet the timings have gone the other way!

david bell : Services that broadcast only part of the day timeshare with others.
For example, it is known that BBC Three and CBBC take turns to use the same capacity.
According to Wikipedia, ITV3+1 timeshares with CITV and The Store:

James Town: First off, check that your TVs and boxes are tuned to the correct transmitter. I guess Sudbury is likely to be what your aerial faces, so bring up the signal strength screen on the following services and observe the UHF channel (frequency) it is tuned to:
PSB1 | BBC One | C44
PSB2 | ITV | C41
PSB3 | BBC One HD (if applicable) | C47
COM4 | ITV3 | C58
COM5 | Pick TV | C60
COM6 | 4Music | C56
One or more of your receivers could, potentially, have tuned to Crystal Palace which is in the opposite direction and which, if available, would be found first during the scan. If so, you should be able to avoid this by having the aerial unplugged for the first 30% of the scan.
You refer to "limited channel selection". Would this be PSB channels only? If so and if your TV is tuned correctly (to Sudbury, I assume) then have you had your "old" aerial installed in the days of four-channel analogue replaced with a wideband one? If not, you may be able to workaround with a signal amplifier (booster).
You mention breakup on the Humax on "non-mainstream" channels. Would these be the COMs? And would these be the ones that the kitchen TV hasn't tuned in?

Rosemary: Indeed, which is why I suggested that Freesat might be better than Freeview for you.
Unfortunately there is never likely to be more channels broadcast from the Rothbury transmitter, and over 1,000 similar stations. This is because there are two types of broadcaster in the UK: "Public Service" and "Commercial".
The Public Service Broadcasters are BBC, ITV, Channel 4 and Channel 5. They have obligations to provide a public service, both in terms of programme content and coverage. For that reason you have a terrestrial television service.
The Commercial broadcasters, on the other hand, are run purely for profit and can choose which transmitting stations they wish to utilise. Due to their private interest they use those which serve the most viewers for least cost.
Broadcasting from the small "filler-in" stations don't make sense to them. See here:

Berni: Have you tried taking the Technika set and connecting it to the aerial lead that feeds your larger set?

Anna: The symptoms you describe usually occur when the receiver (box) has run out of memory for tuned channels. This occurs when signals from other transmitters are picked up before the desired one, the scan running from low UHF channel (frequency) 21 upwards. Winter Hill's channels are at the high end, with PSB2 (which carries ITV, Channel 4 etc) on the highest and is thus found the last.
I would run the scan with the aerial unplugged until about 50% then plug in. If having done this you are missing any channels continue on and try powering it down and then on again to see if ITV, Channel 4 is retained. If it is then run the scan through but plug in a bit sooner, the point being that you were a little too late and it missed some of the lower channels.
In numberical order (and therefore the order they will be found during the scan) the channels from Winter Hill are:
Pick TV - C49
BBC One - C50
4Music - C55
ITV3 - C58
ITV - C59

jule: at800 has been formed by the mobile companies and is charged with alleviating interference on TVs caused by 4G services. It will provide one filter per address, where necessary.
BT Infinity is a broadband service and, as such, is not a TV service. If you are thinking of BT TV, provided using a BT Vision or BT YouView box, then that too uses the "Freeview" signals and so BBC standard definition services may be affected in the same way. The on-demand BBC iPlayer operates over the broadband connection and so is not affected.
If you have another Freeview receiver such as a recorder try watching BBC services on that as a temporary workaround.
Or a set-top aerial might provide enough TV signal whilst not picking up as strong a 4G signal as the rooftop aerial does. This, again, could be a temporary workaround.
Ultimately you need to establish whether 4G signals at 800MHz could be the issue and you do this by contacting at800. If they say it could be then they may send you a filter.
By retuning you have probably shot yourself in the foot as now your TV isn't tuned. If it has manual tuning then go to it and manually tune UHF channel 60. If you find no workaround and wait until the filter comes then try manually tuning C60 as if you have all other channels then an automatic tune will do nothing other than take longer.
