This paper is on improving medium wave signal transmission using a flexible impedance matching unit. The system is T arrangement of impedance network that provides impedance matching between the transmitter and antenna. The parallel feeder used in the medium frequency ground wave signal transmission gives rise to a mismatch between antenna and the generator (transmitter). This network is a lumped reactance that effectively matches the transmitter to the antenna. The vertical antenna used in this range of frequency require a radial wire earth to achieve good ground; with effective connection to the matching network a good path to ground was achieved and noise associated with the transmission line was highly reduced.
Author Keywords: wave signal transmission, impedance matching.

Abstract
This paper is on improving medium wave signal transmission using a flexible impedance matching unit. The system is T arrangement of impedance network that provides impedance matching between the transmitter and antenna. The parallel feeder used in the medium frequency ground wave signal transmission gives rise to a mismatch between antenna and the generator (transmitter). This network is a lumped reactance that effectively matches the transmitter to the antenna. The vertical antenna used in this range of frequency require a radial wire earth to achieve good ground; with effective connection to the matching network a good path to ground was achieved and noise associated with the transmission line was highly reduced.
Author Keywords: wave signal transmission, impedance matching.
