Question

Radio station K5MC has a transmitting antenna with an impedance of 70-j40 ohms at 21.0 MHz. The distance from the transmitter to the antenna is 90 feet. Design a single- stub matching system for a lossless line of 50 ohms so that the transmitter will be matched to the antenna system. Assume that the velocity of propagation along the line is 0.66c (c 3.108 meters per second). Be sure to give physical dimensions of the matching system 2.
