I live in Banbridge and can not receive any freeview chanels at all. Is this likely to change?
link to this comment |
John: In October the Banbridge relay transmitter will become a Freeview Light transmitter. This means that it will carry Public Service Broadcaster (PSB) services only, those being BBC, UTV, UTV+1, ITV2, Channel 4, Channel 4+1, E4, More 4, Channel 5, and the four HD services.
In order to receive the full range of services, you will need to receive from a main station, probably Divis, if you can.
If you have an aerial on Divis now which picks up the four analogue channels, then it is "likely" to work after switchover.

Again Dave, John may get Divis post DSO when the power increases yo 100/50kw.
You can check what will be available after DSO by using Digitak UK's postcode checker.

Saw on the news yesterday that RTE1, RTE2 and TG4 will be available on Freeview in NI after DSO. Will viewers in NI need a Freeview HD box to watch? Will the RTE channels be broadcast in DVB/T or DVB/T2?
