Local TV on Freeview "radiation patterns" update
This is an update on the process of adding the coverage maps for these services to UK Free TV.
The following diagrams are the input diagrams - taken from the Ofcom licence documents.
These diagrams show where the output will be at the full power (the green line is on the outside circle), no power (the line is in the centre) and where it is restricted (the line is between the two).
These will shortly be used to create the coverage maps.
Charles Stuart: The Croydon transmitter will provide coverage to the south-east, while Crystal Palace's service won't cover that area. Presumably that's easier to build than an antenna array serving the whole area off Crystal Palace itself - it may be down to some other tenants on CP being in the way, given that the Croydon aerial is so much further down the mast.
The Croydon and Crystal Palace services have been assigned the same frequency, so they will be running as a single frequency network.
There was certainly criticism from the candidates for the London service that it wouldn't actually cover London all that well, this may be the best compromise that Comux and Arqiva could come up with.
