Charles: Remember that Crystal Palace broadcasts horizontally and Reigate so vertically. It might be worth adjusting the aerial to point to Crystal Palace.

Dave: No, it will stay as it is. Digital UK indicates that it is at 23.4kW. Unusually the power is apparently slightly lower than previously anticipated (the owner of this site is waiting for confirmation as to the powers).
The new HD multiplex is available from 30 transmitters only, and on lower power than the other channels. There is a second "new" HD multiplex to follow.
The plan for these 30 transmitters has been drawn up and will not change before the end of 2018 at the earliest. At that point frequencies for TV may be replanned which might increase coverage of these quasi-national HD services.

dennis: What are you using to record?
If it's a recorder with a hard drive in (a PVR - personal video recorder) and it has its own tuner in then you should use that tuner as the picture will be better quality than if you took it from the TV via the scart which is analogue which is the reason for loss of quality.
The scart socket, usually the first one only (e.g. EXT1) works both ways.

Diane Dean: It's not "illegal"!!
Yesterday is a private concern run for profit and has no obligation to make itself available for free on any platform.
Like other commercial television channels it generates revenue from advertising. The cost it incurs to be on Freeview is, evidently, greater than the amount it generates from advertising and thus it makes a profit. That is, because there are so many Freeview viewers the advertising revenues add up.
On satellite, it is only available subscription via Sky. So Freesat viewers can't watch it and Sky viewers who don't have an appropriate subscription can't watch it. The reason again comes down to money, something which you appear not to consider. Evidently it is more lucrative to go with Sky's subscription than be free-to-air on satellite.
You also say that "Channel 19 has been removed from the digital list". What "digital list"? It is on logical channel number 19 on Freeview for those who can receive all Freeview channels.

Caroline Wilkinson: If you have lost reception of all channels on two independent aerials then this would seem more likely to be some sort of local interference.
The fact that the two aerials are separate means that we can discount possibilities such as water having gotten into the cable, or a faulty joint.
There has been no recent change in the Sutton Coldfield mast which might co-incide with your issue.
The reason for the difficulty with reception from Sutton Coldfield is down to the fact that you don't have line-of-sight, what with high ground around Basford Grance and at Highcroft and Gorsty Hill. See the terrain plot:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
It is worth speaking to neighbours to see whether they have the same issue, particularly those in the adjoining property whose aerial(s) may be in close proximity to yours on the chimney stack. (Do check that they aren't using satellite exclusively.).

Caroline Wilkinson: Confirm all multiplex channels are unavailable. A multiplex is a single signal which carries multiple services. There are six multiplexes; check one service on each to see if it is present:
BBC One
ITV
BBC One HD (if applicable)
ITV3
Pick
4Music

Andrew: Such queries cannot be addressed without knowledge of your location, preferrably in the form of postcode or that of a nearby property such as a shop, this being to check predicted reception in the area.
Based on the information supplied, a whole variety of possibilities spring to mind. These include the downstairs TV being tuned to the wrong transmitter for BBC SD and radio, and too high a signal strength.
There is no such thing as a "digital" aerial as against an "analogue" one. It's the frequencies that the signals use that drive choice of aerial. Aerials installed for analogue are suitable for reception of PSB (Public Service channels - BBC, ITV, C4 etc); its the COM (Commercial - ITV3, Pick, 4Music etc) channels that might require a different aerial for some transmitters.

Alan Mason: They're on lower power which would explain why the strength is lower!

Glenys Sephton: Absolutely not as different frequencies are affected in different ways.
Have you fitted the filter behind the TV set?
If you have a booster then the filter should go before the booster.

Charles Stuart: That said, I don't think it's that critical and there are probably factors that will be more likely to cause poor reception such as objects between the transmitting and receiving antennas.
