  Be sure to pay attention to the "Fresnel Zone" references in this
document. While not particularly accurate, it does refer to the problem of
Fresnel Zone intrusion that can cause problems with your path. In other
words, an optical line-of-sight path is not necessarily a good RF
path, so don't bother installing it if you're not going to engineer it.
