TV aerial not working.

darich

I think it's unlikely the co ax conductors are touching since I've trimmed the cable a few times and tried both aerials a few times so for the same thing to happen approx 5 times seems unlikely although not impossible.
According to the site A.Penny quoted, my transmitter does the step 1 and step 2 in June of this year. Final situation (whatever that means!) is June 2013.

Going by what you guys have kindly suggested so far, my gut feeling is that the cable is damaged...possibly by shorting it although I didn't know it was possible to "short" an aerial since there is no current in it......but since I'm on here asking these questions it shows what my level of knowledge is!!

I think my next step will be to buy a few metres of co ax cable and a replacement splitter and replace what I've corrently got connected.

I'll give it a go tomorrow night and post back what happens.

many thanks

switch your tv over to analogue tuner, see if you get a picture

Fit your aerial back on to the roof, as said earlier, a loft is not the best place for a TV Aerial.

Or fit a bracket to the wall and use a mast. That is what I did. You can get very good Log Periodic aerials for about £20.

Sounds to me like the problem is because your aerial is now in the loft. IMO fit it back outside, as others have side.

Another possibility, when the aerial was on your chimney, was it also on a mast? ie is the aerial too low, now it is in your loft?

The splitter has been in place for a couple of years and worked perfectly well during that time.
It wasn't upset or damaged by the aerial being removed or by me cutting the co-ax cable.

If it is one that draws its power from the co-ax and you'd not turned off its supply when you cut the cable, you in effect shorted it out and killed either it or the PSU.

No power supply to splitter - it's a cheap plastic thing which cost around £4.
Both TVs were also switched off when the cable was cut

I bought 3m of new co ax cable and a new splitter this evening.
Connected everything up.
Still no signal.

I tried connecting the aerial to analogue TV and get a very bad picture. It's unwatchable. And no sound.

I'm starting to think that something in the roof construction is blocking the signal - I don't think my signal could go from so good to almost nothing by simply moving the aerial a couple of metres into the loft.

I was thinking that I could buy another extension and run it through the open loft hatch and that would eliminate the existing co ax cables.

Looks like I'll need to think about erecting it outside as some have suggested but that won't be as easy as the loft.....and is a lot less appealing!!!

Still interested to hear ideas or thoughts on a solution in the meantime.

thanks

is it pointing in the correct direction, with correct polarisation, with a reflector fitted? take the roofing, wiring and splitter out of the equation and point it out of a window to get the best signal on analogue, then replicate the angle in the loft, the higher it is the stronger the signal, but anything in the way will affect the strength.

If TV Aerials worked OK in lofts, there would be no external aerials.

Just get it refitted to it's old location, sorted.
