Prepared by Andrew Corporation I. RADIATION HAZARD ANALYSIS Alaska Communications Dimond D Data Up Link Hub 3.8 Meter to E115WB C-Band This analysis predicts the radiation levels around a proposed earth station complex, comprised of one or more aperture (reflector) type antennas. This report is developed in accordance with the prediction methods contained in OET Bulletin No. 65, "Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields," Edition 97-01, pp 26-30. The maximum level of non-ionizing radiation to which employees may be exposed is limited to a power density level of 5 milliwatts per square centimeter (5 mW/cm2) averaged over any 6 minute period in a controlled environment and the maximum level of non-ionizing radiation to which the general public is exposed 2 is limited to a power density level of 1 milliwatt per square centimeter (1 mW/cm ) averaged over any 30 minute period in a uncontrolled evironment. Note that the worse-case radiation hazards exist along the beam axis. Under normal circumstances, it is highly unlikely that the antenna axis will be aligned with any occupied area since that would represent a blockage to the desired signals, thus rendering the link unuseable. The parameters which determine the radiation levels for the proposed earth station antenna site follows: Earth Station Technical Parameter Table Antenna Actual Diameter (Enter value) 3.80 meters Antenna Surface Area 11.3 sq. meters Antenna Isotropic Gain (Enter value) 45.6 dBi No. of Identical Adjacent Antennas (Enter value) 1 Note: The Radiation Levels will be increased directly by the number of antennas indicated, on the assumption that all antennas may illuminate the same area.

Prepared by Andrew Corporation 1. At the Antenna Surface: The power density at the reflector surface can be calculated from the expression: PDrefl = 4P/A = 4.72 mW/cm2 (1) where: P = total power at feed, milliwatts A = Total area of reflector, sq. cm In the normal range of transmit powers for satellite antennas, the power densities at or around the reflector surface is expected to exceed safe levels. This area will not be accessible to the general public. Operators and technicians will receive training specifying this area as a high exposure area. Procedures must be established that will assure that all transmitters are rerouted or turned off before access by maintenance personnel to this area is possible. 2. On-Axis Near Field Region: The geometrical limits of the radiated power in the near field approximate a cylindrical volume with a diameter equal to that of the antenna. In the near field, the power density is neither uniform nor does its value vary uniformly with distance from the antenna. For the purpose of considering radiation hazard it is assumed that the on-axis flux density is at its maximum value throughout the length of this region. The length of this region, i.e., the distance from the antenna to the end of the near field, is computed as Rnf above. The maximum power density in the near field is given by: PDnf = (16 ε P)/(πD2) = 3.04 mW/cm2 (2) from 0 to 72 meters Evaluation: Uncontrolled Environment: Mitigation Required, See Note 1 Controlled Environment: Complies to FCC Limits 3.0 On-Axis Transition Region: The transition region is located between the near and far field regions. As stated in Bulletin 65, the power density begins to vary inversely with distance in the transition region. The maximum power density in the transition region will not exceed that calculated for the near field region, and the transition region begins at that value. The maximum value for a given distance within the transition region may be computed for the point of interest according to: PDt = (PDnf)(Rnf)/R = dependent on R (3) where: PDnf = near field power density Rnf = near field distance R = distance to point of interest For: 72 < R < 172 meters Dimond D 3.8m C-Band Rad Haz Report.xlsx 9/18/2017 10:15 AM 2

Prepared by Andrew Corporation We use Eq (3) to determine the safe on-axis distances required for the two occupancy conditions: Evaluation: Uncontrolled Environment Safe Operating Distance,(meters), Rsafeu: In F-F region, See Section 4 Controlled Environment Safe Operating Distance,(meters), Rsafec: 44 4.0 On-Axis Far-Field Region: The on- axis power density in the far field region (PDff) varies inversely with the square of the distance as follows: PDff = PG/(4πR2) = dependent on R (4) where: P = total power at feed G = Numeric Antenna gain in the direction of interest relative to isotropic radiator R = distance to the point of interest For: R > Rff > 172 meters PDff = 1.30 mW/cm2 at Rff We use Eq (4) to determine the safe on-axis distances required for the two occupancy conditions: Evaluation: Uncontrolled Environment Safe Operating Distance,(meters), Rsafeu : 197 Controlled Environment Safe Operating Distance,(meters), Rsafec : See Section 3 5.0 Off-Axis Levels at the FarField Limit and Beyond In the far field region, the power is distributed in a pattern of maxima and minima (sidelobes) as a function of the off-axis angle between the antenna center line and the point of interest. Off-axis power density in the far field can be estimated using the antenna radiation patterns prescribed for the antenna in use. Usually this will correspond to the antenna gain pattern envelope defined by the FCC or the ITU, which takes the form of: Goff = 32 - 25log(Θ) for Θ from 1 to 48 degrees; -10 dBi from 48 to 180 degrees (Applicable for commonly used satellite transmit antennas) Considering that satellite antenna beams are aimed skyward, power density in the far field will usually not be a problem except at low look angles. In these cases, the off axis gain reduction may be used to further reduce the power density levels. For example: At one (1) degree off axis At the far-field limit, we can calculate the power density as: Goff = 32 - 25log(1) = 32 - 0 dBi = 1585 numeric PD1 deg off-axis = PDff x 1585/G = 0.0568 mW/cm2 (5) Dimond D 3.8m C-Band Rad Haz Report.xlsx 9/18/2017 10:15 AM 3

Prepared by Andrew Corporation 6.0 Off-Axis power density in the Near Field and Transitional Regions According to Bulletin 65, off-axis calculations in the near field may be performed as follows: assuming that the point of interest is at least one antenna diameter removed from the center of the main beam, the power density at that point is at least a factor of 100 (20 dB) less than the value calculated for the equivalent on-axis power density in the main beam. Therefore, for regions at least D meters away from the center line of the dish, whether behind, below, or in front under of the antenna's main beam, the power density exposure is at least 20 dB below the main beam level as follows: 2 PDnf(off-axis) = PDnf /100 = 0.030 mW/cm at D off axis (6) See page 5 for the calculation of the distance vs elevation angle required to achieve this rule for a given object height. 7.0 Region Between the Feed Horn and Sub-reflector Transmissions from the feed horn are directed toward the subreflector surface, and are confined within a conical shape defined by the feed horn. The energy between the feed horn and subreflector is conceded to be in excess of any limits for maximum permissible exposure. This area will not be accessible to the general public. Operators and technicians will receive training specifying this area as a high exposure area. Procedures must be established that will assure that all transmitters are rerouted or turned off before access by maintenance personnel to this area is possible. Note 1: Mitigation of the radiation level may take several forms. First, check the distance from the antenna to the nearest potentially occupied area that the antenna could be pointed toward, and compare to the distances appearing in Sections 2, 3 & 4. If those distances lie within the potentially hazardous regions, then the most common solution would be to take steps to insure that the antenna(s) are not capable of being pointed at those areas while RF is being transmitted. This may be accomplished by setting the tracking system to not allow the antenna be pointed below certain elevation angles. Other techniques, such as shielding may also be used effectively.

Prepared by Andrew Corporation Evaluation of Safe Occupancy Area in Front of Antenna The distance (S) from a vertical axis passing through the dish center to a safe off axis location in front of the antenna can be determined based on the dish diameter rule (Item 6.0). Assuming a flat terrain in front of the antenna, the relationship is: S = (D/sin α) + (2h - D - 2)/(2 tan α) (7) where: α = minimum elevation angle of antenna D = dish diameter in meters h = maximum height of object to be cleared, meters For distances equal or greater than determined by equation (7), the radiation hazard will be below safe levels for all but the most powerful stations (> 4 kilowatts RF at the feed).
