FREQUENCY COORDINATION AND INTERFERENCE ANALYSIS REPORT PREPARED FOR U.S. SATELLITE CORPORATION ' MURRAY, UT SATELLITE EARTH STATION (9.2 Meter) PREPARED BY | COMSEARCH 2002 EDMUND HALLEY DRIVE RESTON, VIRGINIA 20191 August 18, 1999

TABLE OF CONTENTS CONCLUSIONS No SUMMARY OF RESULTS SUPPLEMENTAL SHOWING, RE: PART 25.203(C) wo— EARTH STATION COORDINATION DATA B CERTIFICATION 10

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 TNIOLl (REVISED) TECHNIQUES. THE LOSSES WERE FOUND TO BE SUFFICIENT TO REDUCE THE SIGNAL LEVELS TO ACCEPTABLE MAGNITUDES IN EVERY CASE.

3. SUPPLEMENTAL SHOWING RE: PART 25.203 (C) 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 .
