Skipp,
    I actually tried that idea at work a few years ago. Strung up about 250
feet of some cheap, not-very-well-shielded RG-8 down a couple of hallways
that ran below ground level.
Had a 10 watt 450 mhz radio on one end and a 1/4 wave ground plane on the
far end.  Didn't work worth a crap. Made an excellent dummy load. Could work
portables maybe 75-100 feet from the radio standing next to the coax run.
Chopped off 200 feet of the end away from the radio and installed the 1/4
wave ground plane antenna on a conduit where the hallways crossed. Worked
fine. Could easily work 300 feet and two floors away.
    That was my experience trying to save a buck using crappy coax as a
substitute for Radiax. I was also trying to see if I could come up with a
easy way to make a fox-hunt transmitting antenna that would give very
ambiguous direction of radiation. Too bad it didn't work. Now, how do I hide
500 feet of RG-8? Hmm.

73,
Al, K9SI
