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.

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 on 06/04/2018.
