[TowerTalk] weird coax

the construction is similar, but this is thicker than rg-62 and the center
conductor is not 22ga copper or copper/steel like rg-62.  This  stuff is
definitely intentionally lossy, the center conductor is very high resistance
material like nichrome and only 26-28ga.

That sounds like RG-62, a 93 ohm coax that was used a long time ago for one
of the LAN standards of the time. Center conductor is lying inside a poly
tube?

This coax was also used in automobile AM radio antennas ... and I've used it
for an impedance transformer for a turnstile antenna.
