Microwave fades fall into the following categories:
+
*[[Refractivity]]
 
+
* Multipath fading
+
* Obstruction fading
+
* Fading due to a specular reflection
+
* Ducting and propagation anomalies
+
* Rain fading (above ~ 8 GHz)
+
 
+
With the exception of rain fading, microwave fading only
+
depends on the change of the refractive index with height
+
along the path
