Ladder line

Ladder line

Ladder line is an older, simpler form of parallel-wire line, often called open wire line. The configuration looks like a rope ladder, hence the name. It can either be purchased already made by a cable company, or home-made; the construction is easy, though tedious, and originally all radio amateurs made their own open wire line. It consists of two wires, usually either clad in a DC insulator or coated with a durable lacquer, held a constant distance apart by insulated spacers.
