Lost some FTA channels during move

    I already have a Ariva 120 FTA/ Saorview setup and working perfectly fine in one living room but was limited to the analogue terrestrial channels on our other TV.
    With the shut down of analogue only a few weeks away I spent my afternoon running a cable from my dish (quad LNB) to this TV. The dish is at the back of the house so I ran through the attic, out the front of the house by feeding it through the soffit and ran it neatly down the side of the drainpipe and drilled though the plint to end up with the cable at the back of the TV.
    To test everything was working, I brought the Ariva in and connected it up. The Saorview channels are all okay but I have lost some of the FTA. I have all my favourites configured so BBC1 & 2 working but BBC3 & 4 are no longer working.

    Can advise why these channels have been lost?

    The signal strength for the lost channels is still strong so I am at a loss.

    Hi TheCeltictiger,

    I think BBC 3 and BBC 4 don't start til 19:00 each day so if you try again later you should have them if signal strength is ok.

    Have you tried the Ariva back in its original position to see if the channels are missing there as well? If so, could you have disturbed the dish/lnb when you connected the new cable?

    Yes tried it back in the room that I had been using all along and have all channels and working fine... Just seems to be missing the channels in the other room

    What kind of cable did you use (for the problem tv point)? Are there any joints or sharp bends in it?

    Used the standard coaxial cable and there does not appear to be any obvious sharp bends or kinks. There was no joins, just the one run of cable from point to point.
    I do have a fair amount of slack cable in the attic. I not sure if that might be a factor?

    Go back to the dish and swap the cable connection on the lnb. swap the working connection with the non working connection, if the box is working in the second room after this and it is not working in the original room then it is an lnb or cable or connection problem
    Is it a sky dish with a quad lnb?

    whats the length of the run of cable used? Ive found these Arivas dont like awfully long cable runs.

    Standard coax? RG6 or CT100 insulated type?

    It needs to be double-screened coaxial cable, such as WF100 or TX100. Don't use cable with aluminium foil and don't use cable with NO foil.

    There's no such thing as 'standard' cable. It's either good enough for the job or it isn't.

    Is it the same cable as was used for the original connection? If you got it online, can you post a link?

    When I referred to the term standard cable I was meaning that I went to my local electrical wholesaler and informed them what I needed the cable for and they gave me the overcounter offering. I can only assume that the cable that gave was suitable.

    The coaxial cable is the same that has been used previously and has aluminium foil insulating the inner core.

    I purchased 40 meters...so from Sky dish quad LNB, through the attic and down the front of the house and back in the plint, to the back of the TV set is one run of cable.

    I would guess that there is 10-15meters slack in the attic.

    40 metres is quite a long cable run. I would get rid of the excess cable.

    I installed an ariva with about a 50m run. We lost quite a few channels. Shortening the run by digging it underground, solved the missing channels. It may not be the fault your having, but there's a chance.

    Aluminium is a conductor not an insulator and it's not as good as copper. As stated above, you need to make the cable as short as possible and, if that doesn't work, replace it with the proper stuff. (Aluminium foil cable shouldn't be used outdoors because it won't last. Sky stopped using it when they introduced Digital TV.)
