1. CONCLUSIONS



An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
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 RESULTS


A number of great circle interference cases were identified during the interference study of
the proposed earth station. Each of the cases, which exceeded the interference objective
on a line-of-sight basis, was profiled and the propagation losses estimated using NBS
TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal
levels to acceptable magnitudes in every case, except for those cases, where on-site testing
will determine whether sufficient losses exist to avoid interference into receivers operating
by local broadcasters.

The following companies reported potential great circle interference conflicts that did not
meet the objectives on a line-of-sight basis. Additional on-site testing will take place to
determine if sufficient blockage exists to negate harmful interference from occurring with the
proposed transmit-only earth station. Conditional clearance has been granted by these
operators depending the outcome of testing.
