A 300-Ω feedline is to be connected to a 3-m long, 150- Ω line terminated in a 150- Ω resistor. Both lines are lossless and use air as the insulating material, and the operating frequency is 50 MHz. Determine
(a) The input impedance of the 3-m long line,
(b) The voltage standing-wave ratio on the feedline, and
(c) The characteristic impedance of a quarter wave transformer were it to be used between the two lines in order to achieve S = 1 on the feedline.
