Antennas are electrical systems (usually consisting of one or more poles or loops) that transform radio signals (or other electromagnetic waves) to electricity, or electricity to radio waves.

Antennas are electrical systems (usually consisting of one or more poles or loops) that transform radio signals (or other electromagnetic waves) to electricity, or electricity to radio waves. Antennas can take many different forms including half-wave dipoles (with two conducting components) for omnidirectional (one-direction) broadcasting or reception and various antenna arrays, for directional broadcasting and reception. These include Yagi-Uda TV antennas, for 47-68 MHz radio signals, turnstile antennas with two dipoles crossed at right angles for handling horizontally or circularly polarised signals at a frequency of 137 MHz, log-periodic dipole arrays with dipoles mounted at increasing intervals along a boom for 140-470MHz signals. The following companies offer antennas for broadcasting, navigation and remote control.
