A properly designed microwave path is designed around a reliability specification, such as 99.9999%, which translates to about 30 seconds of outage per year. Frequency, weather, terrain, and equipment parameters are all taken into account. I've designed many microwave links that meet or exceed that specification. It's really a matter of getting what you pay for, and working for a customer that takes it seriously enough to spend the money required. Properly designed, a microwave link can exceed the reliability of just about any other transmission medium.
Mel - WA6JBD So in a nutshell, microwave is a band of precision and pinpoint accuracy? Common sense that people shouldnt use wood for anything outside that demands long-term stability. Not only do the elements cause warping, but also prone to termites, etc. Wow! Thanks for all the good input! John Hymes La Rue Communications 10 S.
