[TenTec] Shielded Twin Lead

[Martin, AA6E]

Maybe, but I haven't seen it listed for a long time.  It was sold as a
way to reduce interference (ingress) for weak signal TV reception, as
you note.

For Tx use, it would have a controlled impedance that should not care
about nearby conductors.  However, you'd expect higher loss.  You
should check the max. voltage ratings, too.
