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.
