I have nailed down the source of small puddles that periodically appear behind the telly. Water is coming down the inside of the aerial cable and exiting just where it joins a connector (in-line connector, not a connector plate on the wall). I am not going up there myself, so I guess I will have to pay someone to go up on the roof and seal something. I can see how it might happen, it is just such a bizarre thing. Anyone else had it? TV reception is fine.
Yes, I’ve had this. First indication was digi-box starting playing up and it was rusty around the aerial input terminal. Couldn’t work out why there was a few drops of water in the tv cabinet but then suddenly clicked what it could be.
We had to get a new lead from the aerial (and a new aerial at the same time).
If the TV / satellite coax cable is air spaced, then water can run down the cable if the outside end isn't properly sealed.
I would assume the connection box at the top has sprung a leak or the cable outer has been damaged etc.

Punch a hole at the bottom of the cable outside the house to let the water out.
(Don't do this.)
Serious answer:
If it were me, I'd want that entire cable section replacing, not just a blob of stickum sealing something random. Gods only know what's happened to the cable internally.
It's definitely inside, yes? If it's tracking down the outside, a drip loop before it enters the property would fix that.
I've seen this happen on a number of occasions with domestic oil leaks travelling indoors under the plastic sheathing on the pipe.
Yup. Had this when we bought our house although we didn't know it at the time. Bank-appointed damp specialists insisted it was rising damp and wanted £7k in remedial works to put it right. I only found a few years later when remodelling the kitchen that it was actually an old TV aerial cable snipped off under the windowsill that was funnelling water straight from the roof into the house every time it rained.
As Cougar says, get the whole thing replaced. You've already said you're going to have to pay someone to go up there for a bodge job anyway, may as well pay the minimal extra and get a new aerial cable.

No. But it is interesting to hear it is not such a freak thing. Yeah, best get the whole setup looked at.
I’m an Aerial rigger by trade and this is one of most common faults I get called to. Various causes, aerial cable not secured to the tiles if external cable, if you have a slate roof the wind blows the cable and within a matter of weeks it’s chafed through. Some aerials are designed with a plastic box on the top which can get condensation in it which then runs internally down the cable and into the equipment it’s plugged into.
After a few years on some types of aerial the plastic cap on the top disintegrates and the aerial fills full of water. Nine times out of ten you will need a new aerial and downlead fitting.
Perfectly normal, this is the streaming age

Very good!
Chapeau NW
Is that ^^ an Arial font?
Way more common than you would think uv light eats the outer and water gets in.
Puts the resistance power of the signal up too, foam core is fantastic for wicking water.
Rip it out and renew
I blamed the cat for ages for peeing in the house. Eventually replaced the whole cable.
Second time in months, agree with Cougar. New cable if on inside or drip loop if external travel.
Drip loop won't work as it's like a syphon. Cable needs to have a rise at the aerial i.e run it down the aerial pole and then double it back up and higher than the start of the cable.
Hey - @cogglepin
Our dish is old and keeps losing satellite connection in wet weather. I'm thinking a new LNB and cable is needed. It's above a sloping roof of a ground floor extension to make access a slight pain - as in, I cannot get to it with my ladder safely.
What's a typical cost for new LNB and cable, plus realign?
This issue only serves to highlight the shoddy, slapdash methods employed by so-called experts in TV/Satellite industry. Get it installed double quick and move on to the next overpriced punter.
Its dead easy to prevent these sorts of problems with use of sealants, amalgamating tape, silicon grease etc etc but it takes an extra 5 minutes so they won't do it. Ive got stuff thats been in 25 years and good as new.
Cable must be replaced as most have said, and you can try asking the installer to seal all conections including those inside junction boxes as these covers can and will drop off at some point.
