Sinead: Do you just have the one aerial?
Do you have another aerial pointing a bit clockwise of south which you used previously to receive RT from the Republic? If so and this is connected to the aerial lead coming into your lounge, then this could be relevant to being unable to receive the NI Mux on C39.

Sinead: As Carl says, ensure that there isn't something like a Sky box that could be interfering. If there is, then for test purposes, connect the incoming aerial directly to the Freeview HD receiver box you are trying to get RT channels on.

I have just got one aerial pointing out towards the Black Mountain. My neighbours have 2 aerials. I am missing the long horizontial one, so I will get this sorted. I don't have Sky so that isn't the problem, it must be the aerial.
Carl, My friend updated her I-Can box last night with the software update, she lives in another part of Belfast and since the update has been able to receive RTE, RTE2 and TG4.
Thanks for the advice to dat, I will keep you posted on how I get on.

Another thought occurred if the aerial has been up for quite a while it may be an older Group A type for Divis which cuts off at channel 37.
As channel 39 falls into the Group K band which covers channels 21 - 48.
