[BC] 5.8 Ghz STL's

[bruceb@nulogic.biz]

In response to Mike McCarthy's comments, NuLogic does have an 
installation in Tucson that was working with integrated 1.5 foot 
antennas for a distance of approximately 26 miles at 99.97% 
availability.  The antenna dish was upgraded to a three foot at each 
end and for the 26 mile near-line-of-sight transmission the 
availability is 99.999%.  Please contact me at 480-214-6004 or Paul 
Davis at 480-214-6002 for questions or additional information.
