NOTE:
THE BALUN IS OPTIONAL AND STRONGLY RECOMMENDED (SEE ACCESSORIES AT THE BOTTOM OF THE PAGE).
Although the dipole can be fed directly or with a choke made with coaxial cable, the use of a balun, depending on the type used, helps to better symmetrize the voltages or currents thus allowing for a cleaner radiation pattern.
