Question B-006-006-011

If the centre impedance of a folded dipole is approximately 300 ohms, and you are using RG8U (50 ohms) coaxial lines, what is the ratio required to have the line and the antenna matched?

Correct Answer

6:1

Explanation

The required impedance transformation ratio is 300 Ω / 50 Ω = 6. A 6:1 impedance ratio balun would be needed.
