mike shaw: "The one on the Wirral" is Storeton and it only carries PSB (Public Service) channels, hence the channels you are having difficulty with are the COM (Commercial) ones which you are probably receiving from Winter Hill.
The general idea for Storeton Wales transmitter is that it and Winter Hill are roughly in line and so a single aerial should work for both.
Perhaps your aerial could do with turning a little clockwise, nearer the direction of Winter Hill.

mazbar: Whilst you are correct, Mike Shaw lives on the Welsh side of the transmitter and therefore not able to receive the COMs from it, even if he wanted.
The Storeton transmitter relays the PSB channels from Moel-y-Parc. It broadcasts them directionally, towards Wales, using horizontal polarisation so as to match that of Winter Hill. It also broadcasts the PSB and COM channels as a relay of Winter Hill, these being vertically polarised and radiated in the opposite direction to the Welsh PSBs. For that reason Mike Shaw will not be able to receive them and will probably have to use Winter Hill for them.

mike shaw: From your location, Storeton is on a bearing of 19 degrees and Winter Hill 38 degrees. Hence your objective is to have your aerial pointing somewhere between the two, which allows you to receive from both transmitting stations, if this is possible. For this reason aerials of different houses may be pointing in ever so slightly different directions.

m botchin: Without knowledge of your location, preferably in the form of postcode or nearby postcode such as that of a shop, it isn't possible to give guidance on expected reception possibilities.
However, the Commercial (COM) channels which cary Russia Today, Al Jazeera and others are generally the first ones to show poor reception. Therefore, bearing in mind I have no idea as to the transmitter you are using, either you have too much signal, as suggested by Brian, or your TV is tuned not to the transmitter to which your aerial faces for BBC, at least.

stef: Some of the 4G services will use the 800MHz frequencies which are the highest of those used for TV.
The retune for Waltham a few weeks ago formed part of the national clearance of the 800MHz band. The signal for BBC standard definition services moved to a lower frequency. This change did not involve the 4G services coming on air at the same time - it was simply to clear for use soon.

stef: at800 is responsible for investigating interference to Freeview signals and taking steps to remove it. It is not responsible for the clearance of the 800MHz signals, which is what happened at Waltham a few weeks ago.

Bob: No!
This one keeps coming up and the answer is still the same:

Bob: A look at your road on Streetview shows houses with aerials on Mendip and Hannington which may be able to pick up all the channels. The photograph even shows a parked van belonging to an aerial installer!

John V Osborne: If you aren't bothered about which regional programming you get then go with the tranmsitter that gives you the best reception.
You may get improved reception from Sandy Heath with an aerial that is more sensitive on 48, 51 and 52 - this being a wideband or even probably a Group K.

With your current aerial being a Group A one, then it is probably only suitable for receiving all channels from Crystal Palace, and as such rotating it might be your best bet.

John Martin: I presume you are using a HDMI connection if it is a separate receiver.
