Hi Herb and all,
When I was in the Army, 1958 to 1960,, I was a "Field Communications Crewman".
It meant, I helped string telephone wire.
We used what was called WD-1TT. It was two separate conductors. They were
twisted, not molded together. Each conductor was made of 3 steel wires and 4
copper wires making a 7 strand conductor. It might have been 4 steel and 3
copper.
I have never found listings for WD-1TT on eBay. We spliced it by stripping
about 10 inches from each conductor and tying a square knot and twisting the
loose end on the conductor and covering with friction tape and then Scotch
electrical tape. We could run 3 telephone circuits on 2 wires and ground with
isolation transformers.
Regards...Price W0RI
With steel being very lossy AND magnetic AND frequency
dependent, the characteristic impedance of this
stuff is likely to be complex and frequency varying.
I don't see how it would ever work well for a
reversible beverage.
