Abstract
Abstract A directional transmission cable is disclosed which has a plurality of insulated conductive wires. The cable also has a source terminal and a destination terminal. A first connection of a collection of more than one of the wires is made to the source terminal. A second connection of less than all of the collection of wires is made to the destination terminal. A faithful transmission of a signal is made from the source terminal to the destination terminal.
