RigNet SatCom, Inc. EXHIBIT A Radiation Hazard Study 9797 This study analyzes the potential Radio Frequency (RF) human exposure levels caused by the Electro Magnetic (EM) fields of the above—captioned antenna. The mathematical analysis performed below complies with the methods described in the Federal Communications Commission Office of Engineering and Technology Bulletin No. 65 (1985 rev. 1997) R&O 96—326. Maximum Permisible Exposure There are two separate levels of exposure limits. The first applies to persons in the general population who are in an uncontrolled environment. The second applies to trained personnel in a controlled environment. | According to 47 C.F.R. § 1.1310, the Maximum Permissible Exposure (MPE) limits for frequencies above 1.5 GHz are as follows: *« General Population / Uncontrolled Exposure 1.0 mW/icm2 * Occupational / Controlled Exposure 5.0 mW/icm2 The purpose of this study is to determine the power flux density levels for the earth station under study as compared with the MPE limits. This comparison is done in each of the following regions: 1. Far—field region 2. Near—field region 3. Transition region 4. The region between the feed and the antenna surface 5. The main reflector region 6. The region between the antenna edge and the ground Input Parameters The following input parameters were used in the calculations: Parameter Value Unit Symbol Atenna Diameter: 2.4 m D Antenna Transmit Gain: 41.70 dBi G Trasmit Frequency: 6175 MHz f Feed Flange Diameter: 13.10 cm d Power Input to the Antenna: 55.00 W P Parameters The following values were calculated using the above input parameters and the corresponding formulas.

RigNet SatCom, Inc. EXHIBIT A Behavior of EM Fields as a Function of Distance The behavior of the characteristics of EM fields varies depending on the distance from the radiating antenna. These characteristics are analyzed in three primary regions: the near—field region, the far—field region and the transition region. Of interest also are the region between the antenna main reflector and the subreflector, the region of the main reflector area and the region between the main reflector and ground. Region of Main Reflector Region between Main Reflector & Subreflector Region between Main Reflector & Ground ¥ Figure 1. EM Fields as a Function of Distance For parabolic aperture antennas with circular cross sections, such as the antenna under study, the near—field, far— field and transition region distances are calculated as follows: Parameter Value Unit Formula Near Field Distance: 29.640 m Riy= D2/(4)») Distance to Far Field:; 71.136 m Rff = 0.60D2/(A) Distance of Trasition Region 29.640 m Rt= Rnf The distance in the transition region is between the near and far fields. Thus, RnfS Rt<Rff. However, the power density in the transition region will not exceed the power density in the near—field. Therefore, for purposes of the present analysis, the distance of the transition region can equate the distance to the near—field. Power Flux Density Calculations The power flux density is considered to be at a maximum through the entire length of the near—field. This region is contained within a cylindrical volume with a diameter, D, equal to the diameter of the antenna. In the transition region and the far—field, the power density decreases inversely with the square of the distance. The following equations are used to calculate power density in these regions.
