    Weird reception issue

    Weird reception issue 11th Jul 17 at 8:29 PM
    We have a splitter in the house feeding 3 TVs. Aerial guy has tested the signal and says its plenty strong enough to handle 3 tvs. Anyway had no issues whatsoever with it, then tonight the signal strength is jumping all over the place, while the signal quality stays at 100%. Bit error rates too and kept losing signal. No other TV in the house was effected. I changed the cable leading to my TV into a different port on the splitter to check its not the splitter, yet same results.

    Anyway left it 10 mins, and everything is back to normal. 100% signal strength on all channels. What could cause their brief issue? Its raining abit outside by nothing major. I can only think of 2 possible causes

    1) The cable over the roof has been damaged over the years (although that doesnt explain why its ok now) or
    2) There was a bird on the aerial/cable? Would a bird seriously effect the signal though? I noticed the other morning 2 big birds near the aerial but again why only effect 1 tv?

    None that i know of, although not sure how you can find out if new basestations have been built. In what way would that cause a signal dropout on 1 tv in the house for a short period? As i understand 4G and Freeview frequence can interfere with a small number of homes but it happens all the time, not just for 10 minutes like in my case. Not to mention the other TVs were uneffected

    Have you checked/remade the coax plug connections on the TV/splitter ends of the cable? May be a bad connection.

    Rain ? Either heavy rain affects signal reception, or the cable path lies in an area that fills up with water in heavy rain, and works again when it dries out . I had this.

    It was raining yesterday but nothing major. And when the issue stopped, it was still raining a little. Never had this before but will see next time it rains. The cable is over the roof so no chance of standing water

    Transmiiter Fault

    Sounds to me like a transmitter fault or maybe weather related degradation.

    This "tool" can identify the former

    If it's only affecting one of the TV's then it could be the TV itself, not all TV's are made equal (even if they're the same model). If it happens again try moving the TV to a different connection to rule it out.

    No faults listed. And if it was a transmitter fault, why were the other TVs in the house not effected on freeview? I suspect its the cable going to that TV that's at fault. Whether its degraded due to weather, or some bird was having a nibble on it I don't know. Until it happens again hard to pinpoint

    It is on the longest cable yes, as its the TV in the backroom, with the splitter being near the TV downstairs at the front room. Just want it to rain now so I can see if it happens again

    Does the cable pass anywhere where it could be rubbing and have a hole in it, or does it have any serious bends in it?

    Its over the roof so hard to inspect it, guess the wind maybe rubbing it against the tiles although never experienced this happening.


    If it happens again I will put another tv on that connection to see if it still does it

    Have you checked the entire run of the cable from the splitter to the last TV? A kink could mean a damaged inner core.

    As it runs over the roof of the house and happened late last night, not fully no. No kinks where the cable enters the house into the splitter. Outside I had a quick visual inspection and doesn't seem to have any kinks, runs up the wall of the house, over the roof into the bedroom and looks ok, but not been on the ladders to have a proper look.


    Its was installed many years ago and never had issues before yesterday tho
