EXHIBIT A - ANALYSIS OF ENVIRONMENTAL IMPACT

RF NON-IONIZING RADIATION ANALYSIS:

A DETAILED RF NON-IONIZING RADIATION HAZARD ANALYSIS WAS
CONDUCTED AND IS ATTACHED AS EXHIBIT C.

USING THE ASSUMPTION THAT ALL AVAILABLE TRANSMITTER POWER IS
APPLIED TO THE IFL INPUT, HARMFUL LEVELS OF RADIATION WILL NOT EXIST
IN REGIONS NORMALLY OCCUPIED BY PERSONNEL AS DEFINED BY ANSI
CRITERIA (ANSI SPECIFICATIONS REQUIRE THAT PERSONNEL NOT BE
EXPOSED TO LEVELS OF NON-IONIZING RADIATION EXCEEDING 5 mW / cm2.)

ANTENNA SIZE AND DESCRIPTION OF SURROUNDING AREA:

THE EARTH STATION IS LESS THAN 31’ IN DIAMETER AND IS LOCATED IN A
RURAL ENVIRONMENT ON A 100+ ACRE PARCEL. THE ANTENNAS ARE IN A DIP
AND BARELY VIEWABLE FROM THE DIRT COUNTY ROAD.

ADDITIONAL PRECAUTIONARY SAFETY MEASURES:

PROTECTIVE FENCING WILL BE INSTALLED AND APPROPRIATE WARNING
SIGNS WILL BE POSTED.

EXHIBIT B - ANALYSIS OF NON-IONIZING RADIATION

HARMFUL LEVELS OF RADIATION WILL NOT EXIST IN REGIONS NORMALLY
OCCUPIED BY PERSONNEL.
CRITERIA: ANSI SPECIFICATIONS REQUIRE THAT PERSONNEL NOT BE
EXPOSED TO LEVELS OF NON-IONIZING RADIATION EXCEEDING 5 mW / cm2.

THE FOLLOWING ANALYSES SUPPORT THIS DETERMINATION:

FAR FIELD ANALYSIS:

EFFICIENCY = = G/( *D/ )2 = 0.610
ANTENNA GAIN = 60.7 dBi (lin 1,174,898)
ANTENNA DIAMETER = 9.3 Meters
LAMBDA = 3*108 Meters / 14.25*109 Hz = 0.0210526
POWER MAX AT FLANGE = 1350 Watts (31.3 dBW)
DISTANCE TO FAR FIELD = 2*D2/
= 172.98 / 0.0210526
= 8217 Meters
ON-AXIS POWER DENSITY = G*P/4* *Far Field Distance2
= 1,174,898 * 1350 / 12.56637 * 67,519,089
= 1.869 W/m2
= 0.187 mW/cm2
LEVEL IS LESS THAN THE 5 mW/cm2 MAXIMUM ANSI LEVEL PERMITTED

NEAR FIELD ANALYSIS (Parallel Beam Region & Transition Region):
PARALLEL BEAM REGION ANALYSIS:
DISTANCE TO END OF PARALLEL BEAM (CYLINDER) REGION:
= DIAMETER2 / 2.5 *
= 86.49 / 0.0526315
= 1643 Meters
POWER DENSITY AT END OF PARALLEL BEAM REGION
= P / CYLINDRICAL PARALLEL BEAM AREA
= 1350 / 67.929
= 19.87 W / m2
= 1.99 mW / cm2
LEVEL IS LESS THAN THE 5 mW/m2 MAXIMUM ANSI LEVEL PERMITTED

TRANSITION REGION ANALYSIS:
THIS REGION WILL DECREASE INVERSELY WITH DISTANCE BEGINNING AT THE
END OF THE PARALLEL BEAM REGION AND WILL NOT EXCEED 1.99 mW / cm2
LEVEL IS LESS THAN THE 5 mW/m2 MAXIMUM ANSI LEVEL PERMITTED

ADDITIONAL PRECAUTION: Personnel will not be permitted within 1 meter of
the front aperture cylinder during normal operations.
