i have a freesat hd box and live in west belfast can i get rte cannels

binzer: Not with Freesat unfortunately.
You may be able to receive it from Black Mountain, for which you will need a Freeview HD receiver (even though the pictures are standard definition).
Or you may be able to receive the full Saorview service from Clermont Carn in Co. Louth. For this, you will probably require a Freeview HD receiver although some standard definition ones have the capability to show Saorview pictures. Or a Saorview-branded receiver will do the trick (again, if you can receive it at your location).

Hi all!
Is anyone else not currently receiving the NIMM on UHF Channel 39 since yesterday (10th December 2013) - is it off-air?

Hello, I really hope you maybe able to help.
I have one aerial fixed to my chimney. it has two (aerials), coming from the pole which is secured to the chimney.
My aerial has recent been removed and place on the back chimney. I now cant find the same reception as I used to be able to get.
In the past I could get BBC 1, BBC 2, RTE 1 with a clear picture. Now I cant get any of these stations only UTV poorly and I cant understand why.
I have no knowledge in this field of work but if I was guess my way forward, I would like to find the direction of which the aerials should point and then I might be able to make some progress. (I have looked at other houses aerials and there is no pattern to suggest which way to point.)
Any help would be greatly appreciated!!
My post code is BT147HH, abbeydale cresent
Rgds,
John

john evans: There are a number of possibilities of how they might have been and how they might best be now. Do these aerials feed into the same cable so you can watch the output of both on the same TV/box? Are they vertical or horizontal? When you received RT One could you also receive TV3?
As I say, there are a number of possibilities and this is complicated by reception of RT and other channels from the South.
However, Divis is on a bearing of 243 degrees with the aerial horizontal. This will give you all the Freeview channels and the local Belfast service, NVTV.
RT One, RT Two and TG4 are available from Black Mountain, horizontally polarised so as to match that of Divis. This is on a bearing of 223 degrees and a Freeview HD receiver will be required in order to pick this up even though the pictures are standard definition. Thus, if you have a single horizontally-polarised aerial then it should be directed somewhere between the two (the idea being that a single aerial will do for both in most cases).
However, if your other aerial is vertically polarised *and* you received all Saorview channels, including TV3, then you must have been receiving from a transmitter in the South (as TV3 isn't carried by Black Mountain). If your aerial is vertical then I would suggest it's probably for Clermont Carn, although I can't give you a bearing, only around 200 degrees.

john evans: As far as your problem is concerned, maybe you could clarify on the following points.
(1) : If the reason for temporarily moving the aerial involved builders, was it them who actually moved it?
(2) : Were the coax cables disconnected from the aerials before the pole was moved?, or was the whole structure (inc aerials with cables attached) just temporarily moved out of the way?
My only reason for asking being, that my initial suspicion would be along the lines of the problem being caused by a faulty coax to aerial connection, or that the cables have been damaged, because by being located at just under 2 miles away from the high powered Divis transmitter, reception should be possible (in theory) with only a short length of wire (3-4 feet or so) connected directly into the aerial socket (circular middle) of your TV or box. (Black Mountain excluded)

Jordan woods: Hi, Jordan. I explained in a post to Margaret Jones yesterday why this is. I will re-iterate here. 'Keep It Country', channel 87, is now one of a group of channels that you can only watch if you have high definition (HD) receiving equipment. A standard (SD) television or any old tv connected to an (SD) Freeview box is unable to decipher the channel 87 signal into a watchable picture and audible sound. To get 'Keep It Country' nowadays, you need either an HD tv set or an HD-ready tv set plus a Freeview HD set top box. You can get an HD set top box online for 43 plus delivery. I f you do, make sure your tv is HD-ready, has an HDMI connection and that the new Freeview HD box comes with an HDMI lead included. One other thing: you need to be using a transmitter that transmits the 'Keep Country' group of channels, called 'COM 7'. Not all transmitters transmit it, which is why i'm telling you. Hope this all helps, Richard, Norwich, Weds 15th. June at 8:45 a.m.
