在党中央和江主席的亲切关怀下，广播事业大发展的又一个春天已经来到我们身边。在此机遇下，许多中波台都在大规模改、扩建天馈系统，以此增强发射效果和扩大覆盖面积。天、地、馈三线系统的优劣，除决定于材料、工程质量以外，更重要的是决定于三线相互匹配程度的好坏；而要 With the cordial concern and care given by the party Central Committee and Chairman Jiang, another spring of great development in broadcasting has come to our side. Under this opportunity, many Chinese-medium-wave stations have been mass-changing and expanding the antenna-feeder system to enhance the launch effect and expand the coverage area. The advantages and disadvantages of the three days system, the earth system and the three-wire system depend on the quality of the materials and the engineering. More importantly, the three-wire system is determined by the degree to which the three wires are matched with each other.
