3.) A lossless air-line (velocity of propagation equal to the speed of light) with a characteristic impedance Z0-40-02 is operated at 20 MHz. With a short circuit replacing the load, a minimum is found at a point on the line marked by a small spot of puce paint. With the load installed, it is found that the standing wave on the line is three and a voltage minimum is located 1 m toward the source from the puce dot. A.) Find the load impedance. B.) What load would produce a standing wave ratio of 3 with a maximum standing wave voltage at the paint spot?
