Peter as i said before they haven't dropped Divis from inclusion in the RTE mini mux scheme, Black Mountain & Divis are being treated as co-sited, they're a mile away and 5 degrees apart. Reason probably being they will run a single channel from both and use the current main array for the mux then adopt the channel 5 array at Black Mountain to fill in the gap below Divis. Makes sense that 5 watts is the mentioned ERP.
Begs two questions the DTG won't answer is does channel 5 analogue come off the air before switchover and will the RTE mux be on air come stage2 dso.

Jordy: In all existing switchovers, Channel 5 on analogue has closed at DSO2, when the channel becomes available to all on D3+4.

Briantist: Chelmsford C5 is a bit of an exception as it belonged more to the London region than to Sudbury, but it went off at Sudbury DSO 2. Still, it *was* an exception.
According to the last timetable published by Ofcom, Channel 5 analogue must switch off by 31 December 2012, but it also still says that for the UTV region as a whole.
I think it's unlikely that analogue C5 from Black Mountain would be switched off before the DSO date.

Mike Dimmick: True, that was an exception in the strictest sense.
I think that the "31 December 2012" date is there for legal purposes, I don't know if Ofcom will go to the trouble of changing the documentation now to reflect the correct date.
Yes, I agree, Black Mountain will continue with analogue C5 until DSO2 in Northern Ireland so the channel can provide a contiguous service for the viewers.

Is it possible to have an indoor aerial in my area to view digital freeview? If so, what sort may be suitable?

Wilfie Morrison: No, a rooftop aerial is required for reliable reception, and you will not get all services until switchover, 24th October 2012.
