P: Silly statement: The aerial should be vertical and not horizontal.

As a sample I took the postcode BT37 9QW which is adjacent to Christ Church and the row of shops.

Digital UK suggests excellent reception of all four of Carnmoney's channels. This, of course, does not take into account obstructions such as trees and buildings which may act to degrade reception.

I suggest you try using the manual tuning function on your receiver. If you enter/select the UHF channel but do not press the button to scan/add services as in such circumstances receivers often behave as signal meters.

If you have more than one receiver (box, TV etc) you might wish to have a look to see which is likely to be most useful as not all have manual tuning. The channel numbers are:

PSB1 - BBC One - C46
PSB2 - ITV - C40
PSB3 - BBC One HD - C43
NI Mux - RT One - C48

The standard definition ones (PSB1 and PSB2) use DVB-T mode; PSB3 and NI Mux use DVB-T2, so if the manual tuning screen has an option for this, ensure it's correct as it won't find the signal even if it's present.

This problem is quite possibly due to signal overload. At that location a16.5 db outside aerial is quite simply overkill (literally only a half a mile away from the transmitter)

I'd suggest P uses a smaller aerial. Any amplifiers in place should definitely be removed.

darren.c: Historically, due to a shortage of available frequencies in Northern Ireland, digital TV was only transmitted from the main stations at Divis, Brougher Mountain and Limavady. Following DSO the owners of the COM multiplexes declined to add the sevice to any relay masts on the grounds that the extra costs involved could not be justified given the relatively small number of extra viewers that might be gained. Ofcom only required that the service continued to serve those homes that were served before switchover, so viewers wishing to receive more than the PSB muxes must either install an aerial on a main station, where reception is possible, or equip themselves with a satellite receiver, which will offer most of the services carried on Freeview.

If you can't get Divis Darren then Freesat is your best alternative, as KMJ has quite correctly explained.
