Jeff,
Yes, 60 - 65 feet per side. As long as you aren't
transmitting,
75 ohm TV coax, or 50 ohm coax of almost any kind will work just
fine. Get it up as high as possible. If you have to 'bend' it
a
bit to make it fit your space, it shouldn't really affect things
very much. It may not be 'better' than what you're using now,
but
it will be different, so you should hear things you may not be
able
to hear now. Good luck...
