Nadenenko's dipole is an antenna for broadband operation. It provides approximately the same impedance over a fairly wide bandwidth, normally for a frequency ratio of 1:2. This simplifies the tuning of transmitters and provides more balanced signal levels for receivers. For its function, it uses what is called a thick wire, that is, the thicker the wire, the wider the range over which it operates. To avoid the need for tubes, this shape is replaced by metal rings that are surrounded and conductively connected to conductors symmetrically spaced around the perimeter.There are usually 6 to 12 conductors. The power supply to the dipole is most often called a ladder. The picture shows one of the possible designs. The masts must be non-conducting and the anchor ropes must be divided by insulators into sections shorter than 0.1 of the highest wavelength used.
