Question

What is the approximate feed point impedance at the center of a two-wire folded dipole antenna?

Answer 1

The approximate feed point impedance at the center of a two-wire folded dipole antenna will be 300 ohms.

What is impedance?

The combined effect of resistance and reactance in a circuit creates impedance, which opposes alternating current.

Consider the flat twin ribbon TV antenna wire with a 300 ohm impedance. A folded dipole's impedance is 4 times that of a half-wave dipole,

A folded dipole's impedance is found as;

Folded dipole's impedance = 4 × half-wave dipole

Half-wave dipole = 73 ohms

Folded dipole's impedance = 73 × 4

Folded dipole's impedance =292 ohms

Folded dipole's impedance ≈ 300 ohms.
