    The only other time I've seen this previously was a signal overload, for example an amplifier in the installation.

    Other than that I can only recommend to recheck any accessible connections, possibility of bad connection at aerial or cable issue.

    Thank you very much. It's my Dad's house. He'll likely get someone to look at it. I'm on a flying visit. Was just after replacing the washing machine door seal and the stations went 🥹



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    A terrestrial meter would be handy in this situation, an installer is probably the way to go.

    Is there any amplifier in the house, distribution amp for example?



  • Registered Users, Registered Users 2 Posts: 226 ✭✭Summitatem


    Nope. Nothing like that. Basic set up.

    Would it be worth terminating cable again? I can do that much but not sure if there's any merit in it



  • Registered Users, Registered Users 2 Posts: 226 ✭✭Summitatem


    Strangely enough all 666mhz stations back to 100% signal and quality this morning.

    Thanks for the help and replies The Cush, the interaction was welcome and helpful.



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    Great, would love to get a meter on that, suspect very strong signal vs. sensitive tuner.

    Roughly how far away is the Spur Hill transmitter?



  • Registered Users, Registered Users 2 Posts: 226 ✭✭Summitatem


    4km according to Google maps.



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    Very close, a set-top would probably work there.

    If it were to continue to be an issue an attenuator between aerial plug and TV reduces the signal strength .



  • Registered Users, Registered Users 2 Posts: 2,397 ✭✭✭Antenna


    All saorview from Spur Hill Cork went off air at 11PM last night (Wed) for engineering work. That is why this happened, no need to worry about contacting installers or getting meters, attenuators , or reterminating cables etc 🙂

    Looks like one MUX came back before the other

    Don't they normally do that during the daytime?

    I'm partial to your abracadabra,

    I'm raptured by the joy of it all.

    A number of transmitters will have breaks to radio signals starting 30 April. The Fermoy one says 30 May, which must be a typo.

    Hey, hoping I could pick your brains.

    Parents house. We've two TVs working off one aerial on the chimney.

    One always works perfectly, the other has a reoccurring issue with RTE1 where the quality of the picture will be very poor.

    Got an engineer out to test the cables and he said there are nothing wrong with them and we changed the aerial.

    Our last option is to change the TV but kinda slow to do that because it's a pretty new smart LG tv.

    Started having issues the other day again after a long time trouble free. Retuned and can't find RTE1 and I think Virgin Media 1 now at all but perfect on the other tv.

    Anyone have suggestions of what could impact just a few of the channels only on one tv and only intermittently?

    Ran a signal test. Getting only 22% and the quality is bouncing all over the place. Does RTE1 require a stronger signal?

    Thanks in advance

    Edit - from what I can tell online, our local tower would be MULLAGHANISH 39km away

    Check out this old thread — how do you split your aerial into 2 rooms ?

    Do you use a distribution system or simply a splitter?



  • Registered Users, Registered Users 2 Posts: 346 ✭✭rounders


    Thanks I'll have a read and a root around to figure out how we split.

    I think it's just a normal splitter



  • Registered Users, Registered Users 2 Posts: 346 ✭✭rounders


    Turns out the person my parents got to fit the aerial was a cowboy. He just twisted the three cables around each other and wrapped them in electrical tape.

    Got a proper splitter today and put it in a waterproof box. 80% signal on both TV's!

    Glad you got it sorted — hope the box is really water proof !





  • All TV and radio services from the Castlebar relay have been off air for the last 15 minutes.

    EDIT: engineering works at the site today between 10am and 5 pm.

    Everyone getting Now70/80s ok , could be my dish again.



  • Registered Users, Registered Users 2 Posts: 22,196 ✭✭✭✭dxhound2005


    Look in the Satellite forum. Thread there about Rewind TV, which is on the same transponder as the Now channels.



  • Registered Users, Registered Users 2 Posts: 5,480 ✭✭✭SCOOP 64


    Seem to have lost Sky Arts.

  • Registered Users, Registered Users 2 Posts: 4,572 ✭✭✭Gerry Wicklow


    Sky Arts has moved from 12070H to 12148H on HD devices.
    On SD devices it has been removed as 12148H is a DVB-S2 mux.

    Forth Mth

    I'm Missing Saorview Mux 2 since last night (RTE1, SKY NEWS ETC )

    MUX 1 is working fine (RTE2, RTE NEWS ETC)

    EPG for all channels is working fine



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭marclt


    did it come back?



  • Registered Users, Registered Users 2 Posts: 1,410 ✭✭✭FRIENDO




  • Registered Users, Registered Users 2 Posts: 56 ✭✭c2r


    It doesn't look like there's any transmitter issues from the 2rn website.

    For Forth Mountain, mux1 is on ch33 and mux2 is on ch36.

    https://ukfree.tv/transmitters/tv/Forth_Mountain

    Are you in any of the areas of interference on the left of the transmitter map? Suir Valley transmits on the same frequencies, and ch36 is at the top end of a group A aerial, if that's what you have.

    Are all the neighbours aerials in the same direction, or are any of them using Mount Leinster instead?



  • Registered Users, Registered Users 2 Posts: 22,196 ✭✭✭✭dxhound2005


    Have a look at the signal readings. There could be some signal on Mux 2, but not enough for a picture. And even with the Mux 1 picture being fine, that could be just above the threshold. Will also be useful for a Before and After comparison if you change things. And looking at the readings is a good way to optimise the aerial position.

    Im still confused or are you talking about ITV3 HD on satellite?



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    I expect UTV, ITV 4 and ITV Be old frequency will be switched off soon too, new frequency 11386 V 27500 has been active since late August

    And France 24 to 11426 V 29500

    Cheers. It's not hard to get confused with posts about satellite channels appearing in the terrestrial forum.



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Seem to have lost pretty much all my channels (antenna). Started little over a week ago where the signal started getting pretty choppy. Thought it was the weather which was unusual in itself as never happened before and the weather wasn't that bad, but just kept getting worse even during the day. Tried retuning all the channels but even though they're mostly all listed, pretty much nothing coming through on them.

    I just ran a check on my TV and it says Signal Strength 100%, but Signal Quality 0%.

    Haven't changed anything myself which would have caused it. Is it likely to be the aerial outside just giving up the ghost?

    Also, I've checked another TV at another TV point so I've ruled out issues with the TV or that socket. Antenna approx. 20 years old.

    I assume there is an amplifier of some sort in the setup considering there's at least 2 TVs fed from that aerial.

    Can you describe your installation?

    The only time I've seen readings like that was when a signal was overloaded.



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Thanks. I think there's some type of splitter/amplifier in the attic, I'll try take a look at it this evening. 4 TV points in the house but I only use one of them (other TVs in the house are just Smart TVs, Chromecast etc, not connected to the aerial).

    Haven't been in the attic in a few months at this stage so haven't done anything which would have disturbed whatever's up there, which is why I was guessing it's the outside aerial on the chimney.

    There's also a dish on the back of the house but that's been there since before I moved in and is unused. The TV point in the Living room has a connection for it as well but again, never used.

    It's something that got progressively worse since about last Tuesday. Some channels were coming in really badly (especially HD channels), some were a bit glitchy but not too bad. The Irish channels were kind of the same; they'd be mostly fine but then could become absolutely unwatchable 10 minutes later. At this stage, there are nearly no channels that are in any way watchable.



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    Is there power to the amp?

    Bypass the amp to 1 TV, how is the signal after bypass?

    Also check any accessible connectors, that they're intact and secure.

    Amps can fail so best to check there first before considering the aerial.

    20 year old aerial, what type, pic if possible.



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Okay, took a quick gander in the attic, so this is what I'm working with:

    The wires are a bit jumbled above so hard to find out which wires go where, so have no idea which of the four from the splitter is for the TV I use. Will try take another look when I've more time this evening. Also no idea what that combiner yoke is, possibly from the unused satellite dish?



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Okay, so from the 4 way amplifier, cables 1, 2 & 4 go to different TV points. Cable 3 goes into the combiner along with the cable from the dish, and then goes down to the main TV socket which has antenna and sat TV points.

    Can't bypass the amp as there are different connections on the wires going into the combiner, and wire is too short to plug directly into a TV. There is a light on on the amp so I guess it's working, I turned it off and on at the plug too.



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    Light on the amp simply indicates there is power there, not an indication that it's amplifying the signal correctly.

    If the satellite dish is no longer in play I'd remove the satellite/terrestrial combiner and use an F-joiner to join the two terrestrial cables together.

    To bypass the amp pick-up one of these f-f coax joiners locally (supermarket /hardware shop) - https://www.freetv.ie/coaxial-coupler-1s/

    Are the two aerials on the roof still in use, one I assume is for reception of the UK channels from NI?

    Can't see the reason why there's two aerial combiners on the mast, one would suffice for two aerials. Could they be masthead amps powered by the unit in the attic?

    How many cables are coming in from the aerials?

    Looks like a mixed old/new setup, brown coax is old low grade cable. Grid aerial is probably a old wideband, pre the release of the upper TV band frequencies to mobile in 2012.

    What is your recommended Saorview transmitter?

    One cable coming in from the aerial, straight into the amp at the side and then splits with the 4 cables. I'll see if I can get a coax joiner tomorrow. Recommended saorview transmitter seems to be 42, 45 Clermont Carn.



  • Registered Users, Registered Users 2 Posts: 15,923 ✭✭✭✭The Cush


    Do you get the Freeview channels via the aerial also?



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Yeah. All Freeview, HD etc



  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    I have roughly the same set up but using a combiner behind the TV with Freeview from one aerial and Saorview from another aerial —- no amplifiers but 2 cables coming into the house into the combiner.

    I had exactly as you describe and replaced the combiner with a A/B aerial switch and the problem went away — I have to flick the switch to change aerials but that's not a problem.

    I never got to the reason why the combiner upset things — one day it would be 100% signal then in the blink of an eye the picture would break up and disappear with the signal strength bar showing No signal,weak signal or excellent signal strength.

    I never lost my Freeview signal as that is a very big signal — I'm 160 miles from Mt Leinster.

    As The Cush says it looks like you have a combiner on your aerial stack with only one cable coming down.



  • Registered Users, Registered Users 2 Posts: 35,125 ✭✭✭✭Penn


    Never had any issues in the 9 or so years I've been here. That's why I'm having to do so much checking about what the current setup is; never had to look at it before. Even forgot I had a satellite dish on the back of the house. I must have become blind to it. Which is why it's so weird that it all went haywire and why I assumed it must be the antenna outside and weather had caused an issue with it, only thing that made sense to me. But worth checking everything else first before getting someone out to get up on the roof.
