The folded dipole has a wider bandwidth than a single dipole.
2.
Moore describes his antenna as " a pulled-open folded dipole ".
3.
The T2FD antenna is a folded dipole.
4.
Near the rear is a single active element, typically a half-wave dipole or folded dipole.
5.
Slim Jim antennas made from ladder transmission line use the existing parallel conductor for the folded dipole element.
6.
Twin-lead also can serve as a convenient material with which to build a simple folded dipole antenna.
7.
The folded dipole is therefore well matched to 300 Ohm balanced transmission lines, such as twin-feed ribbon cable.
8.
They can be viewed as a folded dipole deformed into a different shape, and have rather similar characteristics such as a high radiation efficiency.
9.
Another solution, especially for receiving antennas, is to use common 300 ? twin lead in conjunction with a " folded dipole ".
10.
The folded dipole is similar to the simple half-wave dipole but with the feedpoint impedance multiplied by 4, thus closely matching that 300 ? impedance.
