Topband: Fw: WD-1 Wire impedance

[Richard (Rick) Karlquist]

> 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.

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.
