Tnx Gene: That all makes sense. Radiax for radiating coax which, I suspect,
has openings in the metal outer and I bet the waxy stuff is to keep moisture
from penetrating the dielectric from outside. Fortunately I only gave $50 for
it and it is probably worth something near that for scrap.

Dan:
Radiax is Andrew's version of leaky coax. It is designed to radiate
deliberately throughout its entire length. It is used in such places as
transportation tunnels and ceiling cavities in buildings to bathe the area in
RF that would otherwise not penetrate from outside.
BOTTOM LINE: Not a good material for usual and customary Amateur use.

I picked up a roll of hardline with the following label. 84147 Andrew
Radiax TMRX5-1R Coaxial Cable. It appears to be 7/8 stuff. There appears to
be some sort of waxy material between the OD of the copper outer and the
plastic covering. At least, that is what I find at the ends of the 250 ft
piece. I plan to try a 50 ohm termination and measure the loss soon. Any
ideas?
