测试与调配中波不定向发射天线,采用射频电桥是比较方便的,但如不具备射频电桥,也可采用下述方法测试与调整。1.中波不定向发射天线输人阻抗的测试用集中参数替代天线输入阻抗,根据谐振原理,利用高频信号发生器和高频微伏表进行
Testing and deployment of medium wave non-directional transmit antenna, the use of radio frequency bridge is more convenient, but if you do not have a radio frequency bridge can also be used to test and adjust the following methods. 1. Medium wave non-directional transmit antenna input impedance test with the antenna instead of the central parameter to replace the input impedance, according to the principle of resonance, the use of high-frequency signal generator and high-frequency microvolt meter
