建议使用垂直分离的天线，通过减少多径衰落事件的持续时间和频率来提高视距微波链路的传输可用性。重点是在地面反射可忽略不计的链路上应用于 4 GHz 和 6 GHz 频段。还处理必要的信号处理、利用无源中继器（反射器）的链路以及水上链路。提出了一些新的实验数据。
Vertically separated antennas are recommended to increase the transmission availability of line-of-sight microwave links by reducing the duration and frequency of multipath fading events. The emphasis is on application to the 4- and 6-GHz bands on links with negligible ground reflections. Necessary signal processing, links utilizing passive repeaters (reflectors), and overwater links are also treated. Some new experimental data are presented.
