Risk estimates for lightning faults make use of log-normal distributions for lightning characteristics such as peak current. Simplifications for highly correlated parameters, notably peak current and rate of current rise, justify use of equivalent front time of 2 µs in backflashover calculations for first negative return strokes. The transmission line backflashover rate is also affected by uncorrelated...
Traditionally, cellular radio antennae were connected to base station radio equipment using coaxial feeders. Microwave radio antennae were ether connected with waveguides or coaxial cables, which will collectively be called feeders herein. The feeders would carry the baseband frequency and the RF signal. RF feeders have served the industry extremely well. However as the frequency and the bandwidth...
