    I have a new Hitachi LCD TV that has a Freeview HD tuner built in and supports DVB-T2 and I live in northern Ireland. For some reason I can't seem to pick up RTE or any Saorview channels. The TV is plugged directly into the aerial and we have a Freeview HD box in another room connected to the same aerial which can pick up RTE.

    Any idea why none of the saorview channels are listed on the TV? I just did another network scan and there was no change.

    don't fret about it there's nothing on it anyway. repeats, repeats, all the time.

    It has to be the right kind of aerial. In some parts of the country it might be a VHF or MMDS aerial you have up there, where it's a UHF TV aerial you want.

    What part of the country are you in anyway? I assume you're not receiving any TV channels?
    It's Belfast, and we are getting all the freeview channels, including HD ones, but not RTE

    Right then, if your aerial setup is for local reception only, I'd have thought you'd have RTE1 & 2 at nos. 52 & 53 in your programme guide. If there's a dedicated aerial for ROI reception (pointed Dundalk direction), they would probably appear in the 800 nos.

    Having a 'southern' aerial connected would more than likely prevent local reception of RTE, due to the combiner used blocking the relevant frequency.

    Unfortunately not, hard to diagnose when you haven't a clue about it in the first place :- (

    Is your aerial pointing towards Divis ?

    The RTE channels broadcast from Black Mountain C39 (51-53 LCN's).

    My guess is that you have a Group A aerial which is why you dont receive that Freview Light minimux

    A group A aerial will work fine for the NI mux, certainly one of the later up-to-ch.37 types.

    As I mentioned already, if anything is blocking ch. 39 reception (apart from terrain), it would be a diplexer used for connecting an aerial for Clermont Carn.

    The NI mux is also on ch. 48 from Carnmoney Hill.

    OP, a pic. of what's on your roof would be helpful, I suppose, as at least then it should be obvious if you're set up for reception from the south.

    Anything thats going to drop dramatically will be above 37 even assuming its not an extended Group A. If the aerial was installed before 95 its likely that the drop would be even more dramatic.

    If his signal is borderline anyway, it'll drop like a stone. The majority of the Black Mountain Muxes are in old group A territory. Red Tip.

    THe info screen on the Freeview TV's give the Channel Frequency in any info page ? That will tell you what tx he is pointing at.

    I'll get a photo up tomorrow guys, of what it looks like

    I'd be pretty sure it's not the aerial grouping that's stopping reception of ch. 39.

    And Black Mtn. is actually a group B (vertical) transmitter, for the other Freeview muxes. Divis is group A.

    Yeah, if there's an aerial for reception from ROI, problem could be something like a missing amplifier power supply, & hopefully replacing it would restore reception.

    True and always was.

    I'd asked the question earlier though. Any chance that aerial is pointing at Divis and not Black Mountain. And any chance its a Group A.

    The frequency of the stations that he is getting will give it away. The picture of the aerial may also, but he has a low post count, so he wont be able to upload it as an attachment here.

    Those diplexers (that are supposed to go pass 21-39) are muck - I unfortunately had to put one in line as Clermont Carn shoots over the top of me and the A antenna was just not doing it recently. In doing so, have lost 34 and 39 from Belfast completely. Thankfully, I have everything from Divis and CC over IP from a receiver high up in Dundalk so it don't really matter anymore.

    Below are links for images of the aerial, and the splitter used. The house was originally 1 house, and split into 2 semis, so the same aerial is used for both houses, with a splitter. The big aerial I think is for RTE (?) - it is pointing AWAY from Divis. I'm not sure what the smaller aerial is in the photo.

    Thanks for all your help so far!

    The bottom aerial just looks like a smaller version of the top one i.e. a UHF 'contract' type.

    One of those red boxes I would think is a masthead amplifier for the top aerial, remotely powered from an indoor PSU. The manual for that SLX 'Gold' distribution amplifier makes no mention of line-powering, so the PSU must be upstream of the UHF input, or is missing. Without the masthead amp. powered, there would be no reception from the top aerial.

    Also the red 'short circuit' light appears to be on? What effect this would have on the overall operation of the amp, I'm not sure, but whatever output has the short circuit wouldn't exactly be performing.

    Just to add to the above, the manuals for a couple of their other amps say the whole thing just shuts down when a short is detected, so if that's the case (& the light definitely is lit), your Divis signals are just being picked up on the cable from amp to TV.
