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. WebA folded dipole is about 300 ohms; a regular dipole is ~75 ohms. If antennas in the array can be treated as parallel resistors, then the equivalent single resistor for a 4-element …
