A coaxial cable includes a central conductor including a plurality of twisted conductor element wires, an insulator disposed outside the central conductor, a shield layer disposed outside the insulator, and a jacket disposed outside the shield layer. The shield layer includes a first shield layer and a second shield layer in an order from a position closest to the central conductor. The first shield layer includes a plurality of longitudinally lapped metal wires, and the second shield layer includes a metal tape disposed outside the first shield layer. An outer diameter of the central conductor is 0.2 mm or more and 0.4 mm or less, and a twist pitch of the conductor element wires of the central conductor is 6 times or more and 10 times or less the outer diameter of the central conductor.

A multi-tap distribution box for connection to a main coaxial line carrying high frequency and alternating current power signals, the multi-tap distribution box comprising a make before break jumper that ensures that connection between first and second main line coaxial connectors in the box is not interrupted when a cover of the box is removed.
