If you are receiving from Chartham, there should have been no need to retune as the UHF channels did not change on this relay. It's possible it wasn't getting all the signals from its "parent" transmitter at the time, as with many transmitter changes taking place, some will not return to full service until later in the morning.

You are quite correct, you may need a new aerial, a group K rather than a wideband (better sensitivity as there are no temporary COMs 7&8 from Carmel). If you give us your full postcode or if you put your postcode into About us | Freeview you can see your predicted reception at your location. If any of the multiplexes are not "good" you should definitely go for the Group K.
If you are having issues with the main BBC channels since the retune (and the SDN channels - see About us | Freeview and have retuned it is possible that your aerial is an old C/D group that is not able to receive the new channels sufficiently well, and it may need replacing. You can get free help if you do not have Satellite or Cable by contacting Freeview on 0808-100-0288 see Important changes to Freeview TV signals Important changes to Freeview | Freeview and also see the FAQs on that page in case they may help.
BUT you need to do it NOW as there's a 3 month time limit on the free help.

I would expect the changes to be complete by now. Yes you probably do need a new aerial.

I'd be inclined to egg it a bit and say you are getting occasional pixelation on all the channels you can get.

Without knowing which transmitter you are receiving and a full postcode to see predicted reception at your location, it's not possible to say what the problem may be.
I suggest you check your internal coax plugs and connections, flyleads etc., by unplugging them checking for corrosion, poor connections etc, and plugging them in again. If there've been any poor connections simply unplugging and plugging in again helps clean the contacts.
Also check your aerial hasn't moved or been damaged in any high winds and coax is undamaged. Water ingress can affect reception.

The same multiplexes will be broadcast from Belmont after each of the retune events, one as you know on the 23rd, and two more in Q1 2020 dates TBA.
How reception will change (with each) will depend upon your aerial and your postcode. If you are receiving all multiplexes satisfactorily at present, if you have a wideband aerial, then it will be down to your postcode because some of the COM multiplexes (5/6/7/8) are moving and they will be to channels that are used by other transmitters and potential interference from them could affect reception. Whilst that's the case already with the other multiplexes that aren't moving, you already know what reception you are getting with them.
If you provide a full postcode we can advise, or put your postcode into the DigitalUK checker About us | Freeview to see predicted reception at the various dates.

Meant to add, the change on the 23rd is COM8 moving to UHF56 and becoming an SFN (Single Frequency Network) so you may find the received single is not quite as good as before. COM7 is moving to temporary channel UHF35. At the first retune in Q1 next year COM7 moves to UHF55 and will be a SFN. COM5/ArqA moves to UHF23. In the 2nd retune in Q1 COM6/ArqB moves to UHF26.

If you had True Entertainment (LCN48) and LCN8 (a local station) right up until this current retune, then you must have been picking up a Local Multiplex from another transmitter as no local multiplexes are broadcast from Midhurst - a manual tune might be needed to get it BUT you'll need to know which one it was. Sony moved a number of it's channels some time ago to Local multiplexes.
LCN61 is Sony Channel+1 - see Channel listings | Freeview and is now only on the G-MAN local mux so I doubt you've been getting that for some time.
If you provide a full postcode we might be able to advise on tuning.

We are going to need a full postcode to look at predicted reception at your location before we can offer any constructive advice.

The information here is not up-to-date unfortunately, as the site owner has not been able to keep up with all the changes to over 1100+ transmitters.
Put your postcode into About us | Freeview where you will see the current channels for transmitters you can receive at your location, and the predicted reception.
DigitalUK is the authority for all this information and it's usually up-to-date. See also Channel listings | Freeview and Help | Freeview for latest update information etc.

You will simply have retuned too early. These changes take several hours and with main transmitters when changes involve all multiplexes, it can be around 6 a.m before the transmitter is back on air. Try again, hopefully Dover is now up and running correctly.
