1 . CONCLUSION S



An interference study considering all existing, proposed and prior coordinated microwav e
facilities within the coordination contours of the proposed earth station demonstrates tha t
this site will operate satisfactorily with the common carrier microwave environment .
Further, there will be no restrictions of its operation due to interference considerations .

2. SUMMARY OF RESULT S



A number of great circle interference cases were identified during the interference stud y
of the proposed earth station . Each of the cases, which exceeded the interferenc e
objective on a line-of-sight basis, was profiled and the propagation losses estimated usin g
NBS TN101 (Revised) techniques . The losses were found to be sufficient to reduce the
signal levels to acceptable magnitudes in every case .

The following companies reported potential great circle interference conflicts that did no t
meet the objectives on a line-of-sight basis . When over-the-horizon losses are considered
on the interfering paths, sufficient blockage exists to negate harmful interference fro m
occurring with the proposed transmit-receive earth station .


       Compan y

       None


No carriers reported potential interference cases .
