Antenna - Dipole Tutorial

A dipole is an antenna. It is a fundamental form of antenna consisting of a single wire whose length is approximately equal to half the transmitting wavelength.

The length of a half wave in space is approximately:

length (metres) = 150 / Freq (Mhz) or length (feet) = 492 / Freq (Mhz).

The actual physical length in practice is slightly different from this owing to other factors.

A most popular dipole known to almost everyone is the folded dipole which forms part of most V.H.F. T.V. Antennas.

A type of antenna with two defined opposing radiating elements, both of the proper length for the frequency of operation, and each forming the counterpoise for the other.
