Lawrie: Do you mean you don't get HD channels, or you don't get *any* channels?
For HD channels you need a Freesat HD box or TV. There are a few TVs that can handle satellite signals directly, but most need another box to interpret the signals from the dish. Both Freesat and Freesat HD boxes are available, but only the HD boxes will decode HD channels.
If you have a Freesat HD box, you can find a channel listing here: Channels | Join Freesat . Channels in bold are in HD.
That only applies to freesat-branded boxes. It's also possible to buy free-to-air boxes that will pick up all free-to-air transmissions, but which don't handle the Freesat EPG. For these, you will need to tune them yourself - for a list of free-to-air channels see http://en.kingofsat.net/pos-28.2E-fta_eng.php. (RG47SH)

Hello,
Problem trying to get Freeview HD:
I am in Stafford, receiving Sutton Coldfield, with amplified wideband aerial. Cannot get HD via a Panasonic HD+ unit. All muxes are shown as 100% quality except uhf Ch55 which has become unreliable (especially at night) since about November 2010. Ch55 was consistent via Sony SD Freeview boxes prior to Nov10 but now intermittent also.
I understand the HD transmitter for this area is at Lichfield (slightly more East of Sutton Coldfield).
Also, after Sep11 switchover, what will be on UHF Ch29 and will it be necessary to get K Band aerial instead of a Wideband?
Thanks

Andrew Beckwith: the prediction for your postcode for the HD mux is equal to that of A, B and C. There's no prediction shown for Mux D as it clashes with ArqB from Winter Hill, since November 2009. Winter Hill is nearly directly behind the aerial, but aerials have a limited ability to reject signals from behind and the low-power digital signals from Sutton Coldfield are pretty quiet. (ArqB from Winter Hill is actually at reduced power until after Sutton Coldfield switches over, to reduce problems, but it can't be completely avoided.)
The HD transmitter is indeed Lichfield at the moment, but HD services will come from Sutton Coldfield after switchover. HD services are even quieter, only 4 kW, and the receiver needs more than twice as much signal as Mux 1 to pick up the HD services. There are a few other users of this channel in the area.
There won't be anything on C29. This site shows the frequencies that NGW suggested for possible 'interleaved' local services several years ago. It's a potential frequency allocation for the future. I have suggested to Brian that he does not show them at this stage.
C29 is the *second* such potential allocation - C51 is preferred.
A wideband aerial already covers C21 to C68. If anything launches, you may be able to receive it, although it depends on the power level and radiation pattern. The plan used to choose the interleaved frequencies allowed for a maximum of five channels below the analogue aerial group, and two above - this is because the aerials usually have a bit of gain outside the official limits. See for example Gain (curves), Again . Most Group B aerials will probably still give enough gain to be usable at C29.
A Group B or Group K aerial will normally have more gain for the same size aerial, or alternatively you can have a smaller aerial for the same gain. (RG47SH)

Briantist - thank you for the explanation re HD at Lichfield/Sutton.
I have an aerial oufit visiting today. In September 2011 (switchover) all will resolve itself. Incidently I'm now picking up a weak Wrekin BBC mux UHF Ch26 (their switchover in progress) with the amplified aerial pointing at Sutton.
