Peter Henderson: I have seen reference to Cambret Hill being included in future plans, presumably as this is the only significant area with no general coverage of COM muxes. Regarding politicians showing an interest, the only transmitter I have heard of receiving particular attention was Milburn Muir in Scotland. As a low power relay with a serving a large number of viewers it would possibly have been a viable extension to the network, however as the proposals are to (possibly) make the COM muxes use a SFN in DVB-T2 in the not too distant future it is unlikely that further extensions to the network would be considered before then.

Cambret Hill would be interesting KMJ as it would help out a lot of people in areas around here that can't get Divis. I've noticed the strength of this transmitter has increased significantly in recent months, so it certainly could be an alternative to Divis.
My point about Londonderry is that it's the second largest city in NI, as well as being the second most densley populated area of the province. The fact the ERP is 2 kw only adds to the fact that it's strange it's only a Freeview Lite transmitter.
Still, I've been told most areas in Derry City can receive Limavady, so maybe it's not such a big issue.

After installing the following aerial I am only able to get 4 channels from Carnmoney - RTE1, RTE2, TG4 & RTE Radio on my Humax Youview box:
Labgear 4G Tri-Boom High Gain Outdoor TV Aerial 16.5dB
Designed to minimise the effects of 4G high speed mobile phone signals. Unique tri-boom with folding design. Suitable for freeview and digital terrestrial TV. F-Type Connection16.5dB High GainOutdoor InstallationLength: 1.6m75ohm Balun
Location: Abbots Cross, Doagh Road
Any advice greatly appreciated.
Thanks

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.

KMJ,Derby7:34 PM
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.
