Radio frequency power transmission

When the antenna is not situated close to the transmitter, special transmission lines are required.

[1] The most common type of transmission line for this purpose is large-diameter coaxial cable.

The interior conductor is held by insulators mounted on a circular device in the middle.

On the circular device, there are wires for the other pole of the line.

On a Goubau line, the wave travels as longitudinal currents surrounded by transverse EM fields.
