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 04/27/2018 Page 3 of 10

2. SUMMARY OF RESULTS There were no great circle interference cases identified during the interference study of the proposed earth station. Frequency Coordination and Interference Analysis Report 04/27/2018 Page 4 of 10

3. SUPPLEMENTAL SHOWING Pursuant to Part 25.203(c) of the FCC Rules and Regulations, the satellite earth station proposed in this application was coordinated by Comsearch using computer techniques and in accordance with Part 25 of the FCC Rules and Regulations. Coordination data for this earth station was sent to the below listed carriers with a letter dated 04/27/2018.
