[BC] 5.8 Ghz STL's

[Mike McCarthy]

Agreed...  Line of sight, precipitation and Part 15 limit distances on 
anything above 4ghz. For non-mission critical links which don't need >95% 
reliability, maybe.  But not for STL shots.

Unless you could get a fully licensed/engineered system, including 10' 
super high performance dishes, diversity, and a LOT of Fresnel clearance on 
paths, I doubt anything less would provide the necessary reliability on 
paths extending 20 miles.
