What transformer turns ratio matches an antenna's 600-ohm feed point impedance to a 50-ohm coaxial cable?
Pick an answer to check it.
Answer: A. 3.5 to 1
The turns ratio is the square root of the impedance ratio. Square root of (600 / 50) = square root of 12 = 3.46, about 3.5 to 1. 12 to 1 is the impedance ratio, not the turns ratio.
Tip: Turns ratio = square root of impedance ratio.
