Local TV on Freeview "radiation patterns" update

The local TV services on Freeview that will be starting within the next 12 months are designed to have their output restricted to local areas. To do this, the transmissions are only output in certain directions.

published on UK Free TV

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.

Most of these seem pretty much as expected but what is the Croydon radiation pattern? That hasn't previously been mentioned, as far as I know.

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.

Briantist: I've just noticed that the Mux L table lists aerial height above ground, not height above ordnance datum as used in the other multiplex licences.

So does the map on the Crystal Palace page include the contribution from Croydon? And should there be a map on the Croydon page to show its contribution to the total coverage of the local MUX?

I am now receiving local tv news for Devon and Cornwall, yet live well into Somerset so am not interested in news from a completely different area. How can i obtain my local news programmes?

Eirian Williams: That sounds like your TV has picked up one or more multiplexes from another transmitter during a retune. If you provide a full postcode we can see which transmitters are predicted to be available at your location and offer more specific advice.
