Celia: The communal aerial system is likely to be the issue. As Michael says, speak to whoever is responsible for the property.
Some are fitted with filters that only allow through the frequencies used by the desired transmitter. In the case of BBC standard definition and ITV4/4seven, they are on new frequencies.
ITV3 and Dave are on the same frequencies as they were before.

Celia: If they are using satellite (Sky or Freesat) then it won't affect them.
This is an issue with the aerial system.
As Michael says, you have answered your own question.

Judy Palmer: The signal from Kendal Fell transmitter may also be good at your location and I wonder if your TV is choosing to go with it for BBC rather than Kendal.
Bring up the signal strength screen and observe which UHF channel it is tuned to. Kendal is on C60 and Kendal Fell is on C46.
There is a bit of a gap in the frequencies used by each transmitter so have your aerial unplugged until about 55% (or until it gets past UHF channel 46, if it gives channel numbers as it scans).

Jamie Clarke: If you have a Sky box, or some other 'box' that may output an analogue TV signal (the type we used before digital), ensure that it is not outputting on or near C50.
Try connecting your TV directly to your aerial and then perform a manual scan of C50. Once you've entered or selected C50, don't press the button to scan immediately, but instead wait and see if it gives an indication of signal strength and/or quality.
BBC standard definition services from Winter Hill are now on C50.
COM5 (Pick TV, Dave etc) are now on C49 - do you have these?

Pamela: If your TV or box has manual tuning, try a manual scan of UHF channel 48.

tony: The amplifier maybe. Don't assume that just because any light on it is on that the amplifier is still functional.
I suggest that you try removing the booster, and its power supply should it be separate, and connect the TV directly to the aerial. You may find that there is sufficient signal strength without it.

B Foster: Obviously there can be no definite answer to such a question.
However it is the case that the blades affect the signal. It stands to reason that any 'affected' signal will be changing.
If it were light coming from the transmitter then there may reflections from the blades which move as the blades move. I should imagine that this is similar to what happens to TV signals.

Chris Johnson: If this is a request for help then as it is a signal related issue you will have to provide an idea of your location, preferably in the form of postcode or nearby postcode (such as that of a shop).
The Commercial (COM) channels which carry ITV4 and others do not have as good a coverage as the other Public Service (PSB) ones which carry BBC, ITV, Channel 4, Channel 5 and others. This is the reason why knowledge of your location is imperative.

sean lynch: Which channels are you referring to?
Like the other small relays, Ystalyfera only carries Public Service (PSB) channels.
If you were ever, or are still, picking up any of the Commercial (COM) channels then you must be receiving them from another transmitter. This probably means that your reception is off-beam of the aerial and therefore that it is being used for receiving signals that it wasn't installed for, hence reception may be hit and miss.
See here for a list of Freeview services:

If you are to receive the full complement of channels then Kilvey Hill looks to be your only possibility, if at all (I emphasise the "if").

Jim Whitehill: The 4G pilot tests have been, and are not, anywhere near your location:
Testing | at800
This site is independent of broadcasters. The information is provided to help viewers.
I would suggest that you may be receiving from Sutton Coldfield. I took a look around your village on Google Streetview and all aerials I saw are directed to Sutton Coldfield.
However, there have, according to reports, been no works affecting its TV signals. There are also no changes due to its broadcast channels.
If your aerial is directed to Earl Sterndale then you would only receive Public Service (PSB) channels from there. Any reception of the Commercial (COM) channels would be purely by chance as they would be coming from elsewhere, that is from a direction (and polarisation) which your aerial doesn't point probably Sutton Coldfield, if at all.
