[TenTec] Shielded Twin Lead

[Glassrus]

With all the discussion of twin lead and ladder line, I remembered a
reference in the late Joe Carr's "Practical Antenna Handbook" to shielded
twin lead. He describes it as: "This type of line uses the same form of
construction as TV-type twin lead, but it also has a braided shielding
surrounding it. This feature makes it less susceptible to noise and other
problems."

Has anyone used this cable? Is it still made? Would it be more tolerant to
nearby conductive surfaces?

Thanks,
