What length of extra cables to choose?

What will your use be – the different lengths are because different people have different size rooms, beds, ideas on layout. You may have a small apartment or a large apartment – differs on your layout. It is suggested that you remain 4 feet from the transmitter and 3 feet from the receiver. Also the more the units are spread out the larger the field which acts like a football so the area in middle is much larger than at its source. I think the 3 feet distance is so your getting good coverage and most benefits from scalar wave.
