dam: As above "The commercial multiplexes at Sandy Heath will remain on their pre-switchover channels and powers for a period after digital switchover. SDN will then temporarily move to channel 31 (at 20kW ERP) on 31 Aug 2011, before adopting its final allocation of channel 51 on 18th April 2012. Arqiva A will adopt its final allocation of channel 52 on 23 Nov 2011. Arqiva B will temporarily move to channel 67 (at 20kW ERP) at switchover and then it will adopt its final allocation of channel 48 on 14 Sept 2011.".
Basically, you will ahve to wait for the 14th September 2011.

Pete Carlyon: "please provide a full (not partial) postcode (or preferably enter it in box at the top right)".
You need a rooftop aerial for reliable Freeview reception, loft aerials are not suitable for stable reception.

Keith Couch: As per the comment above, you will have to wait for the service to go onto full power on 14th September 2011.

colin rees: An aerial at that postcode mounted horizontally will be receiving a signal from Ridge Hill, not the Hereford transmitter.

Mark A.: Oh right, an explanation might be in order.
The top is north.
The circles are the level of attenuation, with the outside being 0dB (ie, full ERP) and the inner lines are the attenuation in decibels, up to -18dB with the inner point meaning "no signal".
The actual attenuation patterns are actually 3D, but they are very hard to show in a 2D diagram.
At some point I will adjust the routine that draws the coverage maps to take into account the attenuation.

Nick: As above, the final channels are C41, C44, C47, C49, C56, C58, C60- which means C56, C58 and C60- are "out of group" so you must have a wideband aerial if you want all multiplexes from this transmitter after switchover.

Nick: Well, apart from the rather obvious point that C54 and C68 are not covered by a group B aerial, thus the need for a wideband aerial.
