In this paper, the design method of pre-tuned network in medium wave antenna deployment network is introduced by using Smith circle diagram, and the design flow of balanced impedance of dual-frequency co-tower pre-tuned network is given. The numerical parameters of pre-tuned network are determined by using the variation rule and range and combining matching conditions to avoid complicated formula calculation and quickly and directly reading the diagram.
