What is the max length of the video (composite) wire without having
noticeable picture-quality loss?
Thanks
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
