Tommy Smith: Short of building a tower, maybe 250m to 300m high, on which to mount an aerial directed to Ridge Hill, then I don't think you have a prayer.
Somehow I don't think that you will get planning permission and will have to stick to getting a satellite dish for free-to-air channels.
Refer to this terrain plot between you and Ridge Hill:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
You have Llan-Wen Hill in the way whose summit is 250m above your ground level. It is also 60m above the top of the transmitter mast.
Unfortunately there is no likelihood of Garth Hill carrying the Commercial Freeview channels because those broadcasters don't wish to pay as they don't consider it worth their while (and 1,000 plus similar stations):

Jon: The most obvious thing to do would be to try the Toshiba TV in another room or try another TV connected to the aerial outlet that the Toshiba is connected to.
One possibility is that your distribution amplifier is providing too high or excessively high output. Try turning it down a bit.
Or connect the incoming feed from the aerial directly to the feed to the room with the Tosh in.
Try manually tuning to the BBC services of your transmitter.

Tommy Smith: Unfortunately, yes.
Kington has its own relay and the main part of the town is in a valley so I would warn you that there are probably parts that you will never be able to receive the full service from Ridge Hill and which you would have to rely on the local PSB relay.

Phil Thomas: Sometimes (or maybe all the time - I don't know for certain) with HD receivers, with the manual tune you have to tell it what mode the signal uses.
DVB-T is what Freeview standard definition broadcasts use and DVB-T2 are what HD uses. So if there is a setting on the manual tune screen, then you need to select the latter.
Assuming that there aren't any other transmitters that could be picked up and put in the proper logical channel number slots, then there is a simple way to avoid Rowridge and that is to unplug the aerial for the first 30% of the scan.
You may be able to receive COM channels from Whitehawk or Rowridge (or both). It might be worth assessing which is better and then opting to ensure that the best is used.
Rowridge broadcasts all channels vertically, so your vertical aerial will do for all three, providing that they are there to be picked up.

Phil Thomas: Knowledge of your TV's model number would allow its specifications to be checked.
It requires a DVB-T2 tuner and not just a DVB-T one.

Val Casson: Knowledge of the model number may allow the user manual to be found which would be likely to give a definate answer to your question.
However, if I was looking at the remote and had to use my intuition I would press the button marked "Input" or a circle with an arrow pointing into it. I would expect that this would give a list of inputs (scart, HDMI etc) and included in that list would be analogue and digital TV. Analogue TV may be "ATV" and digital may be "DTV" or one may just be labelled "TV".

Val: The user manual is here:
http://www.home-entertain….pdf
The button you need to press is the "Source" one which performs the same function as I described above. From there you need to select "DTV".
What you have done on the Tosh cannot have any effect on other TVs. Therefore, if there is an issue then it can only be with the particular TV in question (or your aerial system).

brian manley: Some may need a different aerial but some will likely get away with the C/D one (or not notice).
In answer to your question, I should imagine it's to fit in with other transmitters.

However, reception of all channels from Crystal Palace might be possible at your location as the Digital UK predictor suggests and Streetview shows aerials pointing in that direction.

brian manley: One thing that is probably a factor in Greenwich not being given C/D channels post switchover is the ring-fencing of 61 to 68 to be sold off to the 4G mobile operators. Thus, useable C/D is now smaller than it was, in much the same fashion as useable A is now smaller due to ring-fencing of 31 to 34 (or 31 to 37 if you count 35 and 37, previously channel 5 only and 36, previously silent).

Martin Warren: You can get an octo-LNB.
Don't know whether sexa-LNBs are available.
