WebThe length of the dipole is half of the wavelength. Hence, it is called as half wave folded dipole antenna. Frequency range The range of frequency in which half wave folded dipole operates is around 3KHz to 300GHz. This is mostly used in television receivers. Construction & Working of Half-wave Folded Dipole WebWhen constructed of two equally sized conductors, 4 times that of a dipole. So if an ordinary dipole has an impedance of 75 ohms, a folded dipole will be 300 ohms. As with any antenna, the actual impedance can be influenced by proximity to ground, straightness or bending of the conductors, losses, and feedline isolation.
