Default How long can a TV extension cable be?

Right, the new LCD TV has arrived and I've set it up in the kitchen.
Found 77 digital TV channels, 35 Radio, 22 Data/Other (what ever those
are).

**It also found 14 analogue channels**, which astonished me. I had
always assumed a digital TV can only receive digital signals. I've
switched through BBC One, Two, ITV, Channel 4 and Five, no problem.
Five gives the best picture (reception).

Initially, I tried setting up the TV in the living room, the one place
where the picture was grainy on the analogue portable. The LCD TV said
"weak or no signal".

So there's definitely a problem there. To cease with the guess-work I
have measured the actual length of the cable from the amplifier to the
wall plate: 13 metres +/- 20cm

The length to the kitchen wall plate is a lot shorter. I haven't
measured it, but it'll be about 6m
