Hi does anyone know of a company called Aerial Services NI based in Belfast. Can't find a website anymore and the phone's are not answered. Perhaps they no longer trade? They used maybe still do looked after our apartment block in Annadale Embankment. The letting company went bust and can't get a hold of anyone our flats have had no signal since Tuesday night. Thanks

James Vance : Your model of TV will not receive the NIMM RTE/TG4 transmissions as they require a receiver fitted with a DVB-T2 tuner, your Samsung being DVB-T.

Hi James Vance and jb!

James - jb has answered the question regarding the make and model of your set. jb has done the research I would have done to establish the type of tuner in your set. From jb's answer you will see that you will not be able to receive the 3 RTE/TG4 stations transmitted from Black Mountain.

In my first reply to you I included a link to the Digital UK site which included the information regarding the transmitters that you may be able to receive your TV programmes from:

(http://www.digitaluk.co.uk/coveragechecker/main/trade/bt155ag/27/0/85s8ev8f9p8nvo9u6otr93b5g5)

I know the link's address is quite long but if you type it into your internet browser you will be able to see the aerial group you will need. For Divis it lists a Group A aerial and for Carnmoney it lists a Group B aerial.

Just one other thing - this TV set will not tune in the High Definition stations from Freeview although it may be a high definition set it doesn't have a high definition tuner built into the set.

Regards

Kieran

James - I should have said that an aerial for Divis reception is set horizontally while for reception from Carnmoney the aerial is set vertically. That is the elements of the aerial are set horizontally (Divis) and vertically for Carnmoney.

Brian!

What is happening to com8 UHF Channel 34 - detailed above. I see that it has a HD icon against this listing and due on-air December 2013. Is there reasons why this channel is not on-air at this time and which channels will use this multiplex?

Regards
