* The report covers identical antennas with the same operating parameters at
   the same location and coordinated over same portion of the orbital arc;
             accordingly, no additional coordination is required.

     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.


         THE FOLLOWING COMPANIES           REPORTED           POTENTIAL     GREAT     CIRCLE

         INTERFERENCE CONFLICTS WHICH DID NOT MEET THE OBJECTIVES ON

         A LINE-OF-SIGHT        BASIS.         WHEN     OVER-THE-HORIZON LOSSES ARE

         CONSIDERED ON THE INTERFERING                 PATHS,     SUFFICIENT        BLOCKAGE

         EXISTS TO     NEGATE     HARMFUL INTERFERENCE FROM OCCURRING WITH

         THE PROPOSED TRANSMIT           AND     RECEIVE        EARTH     STATION.
