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. Frequency Coordination and Interference Analysis Report 04/10/2003 Page 3 of 10

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. No Carriers Reported Potential Interference Cases.
