It depends what you mean by "noticeable picture-quality loss"

If its just a cheap domestic TV you can probably get away with 50m before it gets a even more blurry. Check the dB/m loss on say belden cables (google!) at subcarrier frequency, ie 3.8 MHz in the US and 4.43MHz in civilised places. See how much cable you need to get a 3dB loss at subcarrier, as a rule of thumb If you use crap cable, you will notice poorer quality pixs on shorter cable

Hello Martin,

Also, you can compensate for increased losses towards higher frequencies by high pass filtering. Of course, that won't work for miles of cable where the signal is down into the noise.
