       On behalf of Hearst Properties Inc., this statement provides the results of a
Radiofrequency Radiation Hazard Study regarding the proposed modification of E010146, a
transportable earth station.   The proposed modification is to change the antenna, associated
equipment, and emissions. The transportable carth station will operate in the "Ku" band with a
transmitter power output of 125 Watts and a Sat—Lite 1.45 meter diameter dish antenna.


       In keeping with §1.1307(b) of the FCC‘s rules, the proposed operation has been
evaluated for human exposure to radiofrequency energy using the procedures outlined in FCC
OET Bulletin No. 65 ("OET 65"). The 1.45 meter dish antenna will be mounted on the top of a
commercial—grade truck such that the distance from the ground to the center of the antenna is
approximately 4 meters.


       The following data have been used with the OET 65 equations for predicting RF fields
for a parabolic aperture antenna:

       At the range ofthe uplink transmit frequencies (14.0 — 14.5 GHz), according to FCC rule
section §1.1310 the maximum permissible exposure ("MPE") limit for human exposure to RF
electromagnetic field is 1.0 mW/cm‘ for general population / uncontrolled exposure and
5.0 mW/cm? for occupational / controlled exposure.

         The following RF power density results were calculated using OET 65 procedures (see

         On—axis (in the main beam of the antenna, oriented towards the sky), the maximum near
field power density is calculated to be 17 mW/cm*. This exceeds the occupational / controlled
and the general population / uncontrolled MPE limits.         Such on—axis locations will be well
elevated above ground and are not accessible by the general public.            Off—axis, the maximum
power density is 0.17 mW/em* which does not exceed the general population / uncontrolled
MPE.


         The applicant proposes to comply with the FCC‘s MPE as described in the following.
This antenna will be located on a vehicle rooftop and conditions will vary from operating site to
operating site.      Because of this, the licensee will establish procedures for the operational
personnel to verify that the antenna is not pointing in the direction of populated areas, and that
access to any hazardous areas are restricted while the unit is in operation.


          The only access to the roof ofthe truck is a ladder that is not accessible by the general
public. The distance from the ground to the center of the antenna is approximately 4 meters.
Operational personnel shall choose transmitting locations such that no buildings, other obstacles,
or human access will be situated in the areas that exceed the MPE limits.             The earth station


                                                                               Chesapeake RF Consultants, LLC

personnel will be trained to ensure that the antenna path is clear at all times while the transmitter
is in operation.


         The earth station‘s operational personnel will not ordinarily require access to the arcas
that exceed the MPE levels while the earth station is in operation.        If access to the vehicle
rooftop is necessary, personnel can easily limit their access to a distance of at least one antenna
diameter away from the antenna and the main beam while the dish is in operation, as these areas
comply with the general population / uncontrolled MPE limit. Authorized and trained personnel
individuals that are covered by the occupational / controlled MPE limit may approach the
antenna to a minimum distance of 0.35 meters from any part of the antenna, provided that they
do not enter the area in front of the antenna‘s main reflector. To assure the compliance with
safety limits, all emissions shall cease whenever personnel must access the area in front of the
antenna or any areas within 0.35 meters of the antenna as those locations may exceed the
occupational / controlled MPE limit.     The mobile unit will be marked with warning signs to
advise personnel to avoid the area around and in front of the reflector when the transmitter is
operating.

                             RF POWER DENSITY CALCULATIONS



NEAR FIELD REGION
       Within the near—field region of a parabolic reflector antenna, the maximum value of RF
power density occurs on—axis at a distance of R,; (Extent of Near Field) as expressed by:


                                              Rar=D/ 42
               where:             Rur= distance to beginning of near—field
                                  D = antenna diameter
                                  1 = wavelength

For this analysis, it is assumed that the maximum value of the RF power density exists
throughout the entire length of the near—field region. For the proposed Ku—band satellite uplink
earth station, the near field extends to a distance of
                                           Rar= 24.97 meters


The maximum value of on—axis RF power density that is possible within the near field region of
the proposed Ku—band satellite earth station antenna can be expressed by the following equation:

                                         Sir=(16nP)/ (zD)

               where:             Sir= Maximum near—field power density
                                  1 = Aperture efficiency
                                  P = Power fed to the antenna


For the Ku—band satellite carth station antenna, the maximum RF power density in the nearfield
is calculated to not to exceed:
                                          Sar= 17.02 mW/em*

       OET 65 states that the "power density at that point (one antenna diameter removedfrom
the center of the main beam) would be at least a factor of 100 (20 dB) less than the value


                                                                                 Chesapeake RF Consultants, LLC

calculated for the equivalent distance in the main beam." Accordingly, estimates of the off—axis
RF power density in the near field region were made with this conservative presumption. For the
proposed Ku—band satellite carth station, the General Population/Uncontrolled Exposure at a
distance ofat least 1.45 meters from the main beam, the near field maximum off—axis power
density is no greater than:
                                        Satom = 0.17 mW/em®

TRANSITION REGION

         The RF power density in the transition region between the nearfield and the far field ofa
parabolic reflector antenna decreases inversely with distance from the antenna.             The far field
region (farthest extent of the transition region) can be approximated by the following equation:
                                            Rf=0.6D°/A

                where:         Rir= distance to beginning of far—field



The beginning of the far field is calculated to be:
                                          Ry= 59.9 meters


The maximum value of on—axis RF power density level in the transition region can be
determined by the following relationship:


                                            St= Sar Rar/ R

                where:         S, = Maximum power density for transition region
                               R = distance to point of interest



Assuming the point of interest is R=Ryr= 24.97 meters where the maximum (upper bound) of the
power density exists, the RF power density in the transition region is:


                 Sar= 17.02 mW/cm> (Maximum predicted density in the transition region)


                                                                              Chesapeake RF Consultants, LLC

The General Uncontrolled/Exposure area will be at least one antenna diameter distant from the
Ku—band satellite earth station antenna and, according to OET 65, the off—axis power density can
be conservatively assumed to be at least 20 dB below the maximum level from the center line
axis of the antenna. Within the transition region, the maximum off—axis RF power density is less
than the maximum value of:
                                       St(oo = 0.17 mW/cm>


FAR FIELD REGION

         For the proposed Ku—band satellite earth station, the maximum possible value of on—axis
RF power density in the far field region can be determined as follows:


                                       Sy=(P G) / (4 x R°)

                where:        Sir= Power density (on axis)
                              G = Power gain relative to an isotropic radiator


For the Ku—band satellite earth station, the maximum RF power density at the end of the
transition between the near field and the far field (R = 59.9 m) was calculated to not exceed:


                                        Sg=7.29 mW/cm®

In compliance with the antenna meeting or exceeding performance specifications under
§25.209(a)(2) of the FCC rules, the off—axis gain of the proposed antenna is 8 dBi (a power gain
of 6.31) or less in any direction 7 degrees or more from the main lobe. The off—axis RF power
density for the Ku—band satellite earth station can be conservatively calculated using the far field
power, gain, and distance relationship as:


                                      Smoa = (P G) / (4 x R°)


                                                                           Chesapeake RF Consultants, LLC

RF POWER DENSITY CALCULATIONS
(page 4 of 4)



Assuming a distance of 59.9 meters from the antenna (the far—field location nearest the antenna),

the off—axis RF power density is calculated to be:


                                     Smoa = 0.0015 mW/em*



OFF—AXIS POWER DENSITY

         The minimum distance required for authorized and trained personnel to approach the
antenna from locations notin the main beam can be determined as follows:


                                        S=(PG)/(4 z R")

                Solve for R (distance), where
                       P = 125 Watts
                       G = unity
                       S$=5 mW/em* (Occupational Limit)

                       R=0.35 meters



        Authorized and trained personnel individuals that are covered by the occupational /
controlled MPE limit may approach the antenna to a minimum distance of 0.35 meters from any
part of the antenna, provided that they do not enter the area in front of the antenna‘s main
reflector.
