If your coax is picking up signal then you have system problems. Just using
coax without proper configuration is a waste of money. You might as well use
hook up wire. In a properly functioning setup, that extra length would
actually be beneficial if it had any effect at all. A length of coax in a
coil can act as a very effective RF choke.

I was looking for a shorter RG58 cable in RS a couple weeks ago
because
my 20' was all wound up (not enough room) and it was causing QRM.

???!!!

Heh. The 20' lead in coax cable for my SW antenna-the cable I'd used
in a pinch when I moved in-was too long for the space it needed to
cover, and it was picking up spurious signals (electronic noise and
such). I know this because the signal would improve when I moved the
coax. So I went to RS to buy a shorter lead in cable.
