                                                 Model 8060 6.1 Meter Earth Station Antenna
                                                 Model 8060 is a 6.1 meter earth station antenna that provides
                                                 superior performance through the use of precision stretch-
                                                 formed reflector panels and a dual-shaped Cassegrain feed.
                                                 Corrugated conical feed horns ensure excellent antenna gain
                                                 and sidelobe performance. Sixteen high-strength aluminum
                                                 panels are durable enough to withstand a range of environ-
                                                 mental conditions. Antenna panels mount to radial trusses
                                                 attached to a central hub.

                                                 The hub also provides a protective enclosure for sensitive
                                                 electronics. The high-strength structural steel tripod mount
                                                 employs an elevation-over-azimuth geometry for easy pointing
                                                 to any satellite within the visible orbital arc. The mount’s stiff,
                                                 rugged construction provides pointing accuracy for continu-
                                                 ous operation, even under adverse wind conditions.

1     Overview
      Determining the region around an antenna where radiation hazardous to human health is a consideration of many
      factors. With a parabolic dish antenna, the region is highly directional and the actual hazardous region is
      dependent on the antenna elevation angle. The following formulae are used to determine the near and far field
      regions. These regions are in the main beam of the radiation pattern, which we will assume consists of a conical
      angle extending +/- 3 degrees from the center axis of the antenna.

      The analysis contained herein predicts the radiation levels around the proposed antenna. The calculations
      contained in this report are in accordance with FCC guidelines as contained in CFR 47 Part 1.1310 and OET Bulletin
      65. The maximum level of non-ionizing radiation to which the general public is exposed is defined for controlled

3   Power Density at the Antenna Surface
    The power density at the reflector surface is expected to exceed the safe limits. The reflector is not accessible to the
    public and will not present a hazard. Terminal operators and technicians receive training identifying the area as
    presenting high exposure levels. Procedures are incorporated requiring that transmitters are not operating when
    access to the reflector surface is required.

    The power density at the antenna reflector surface can be calculated by the expression:
              PDREFL = 4P/A =                                                                            2.43 mW/cm2
    Where:        P = Total power at the feed, milliwatts
                  A = Total area of reflector, sq cm
    Evaluation:
               Controlled Environment (less than 5 mW/cm2 in 6 minutes):                                  SAFE
                                                                 2
               Uncontrolled environment (less than 1 mW/cm in 30 minutes):                        Mitigation Required



4   On-Axis Power Density in the Near Field Region
    The Radiating Near Field Region for a parabolic, circular reflector, is defined as extending from the reflector to a
    distance equal to the diameter squared divided by twice the wavelength. This distance is referred to as the Rayleigh
    distance. In this region the power is nearly all contained within a cylinder of radius 0.5D. As a safety measure the
    highest possible power density is applied to the whole of this region.

    The power density in the Near Field Region of the antenna can be calculated by the expression:
              16*P*h/π*D 2 =                                                                             1.58 mW/cm
                                                                                                                   2


    Where:        P = Total power at the feed, milliwatts
                  h = Nominal antenna efficiency
                  D = Effective antenna diameter, meters

    Evaluation:
               Controlled Environment (less than 5 mW/cm2 in 6 minutes):                                  SAFE
               Uncontrolled environment (less than 1 mW/cm 2 in 30 minutes):                      Mitigation Required



5   On-Axis Power Density in the Transition Region
    The transition region is located between the Near Field and Far Field regions. The power density begins to vary
    inversely with distance from the antenna in the transition region. The maximum power density in this region will
    not exceed the power density calculated for the Near Field region. Once again the power density figures are for the
    On-Axis and contained with a cylinder extending within +/- 1 degree of beam center. Where the antennas are
    normally operated at an elevation angle typically greater than 10°, the actual safe distance in front of the antenna
    may be found in paragraph 10. The formula for the calculation is used to evaluate the power density at any given
    distance in the transition as expressed below:

    The power density in the On-Axis Transition Region can be calculated by the expression:
              PDt=(PDnf)(Rnf)/R
    Where:        PDnf = The Near Field power density, mW/cm2
                  Rnf = Near Field maximum distance, meters
                  R = Distance to point of interest
    For:          186 < R < 447 meters

    Evaluation:
               Controlled Environment Safe Operating Distance, meters:                                     59 meters
               Uncontrolled environment Safe Operating Distance, meters :                                 294 meters


6   On-Axis Power Density in the Far Field Region
    The On-Axis power density in the far field region (PDff) varies inversely with the square of the distance. The
    calculation is performed below:

    The Power Density at the start of the Far Field region can be calculated by the expression:
               E-10log(4pR 2)                                                                                8.30 dBW/m
                                                                                                                        2

               antilog((E-10log(4pR2)/10)/10                                                                 0.68 mW/cm
                                                                                                                       2




    Evaluation:
               Controlled Environment (less than 5 mW/cm2 in 6 minutes):                                     SAFE
               Uncontrolled environment (less than 1 mW/cm 2 in 30 minutes):                                 SAFE



7   Off-Axis Power Density Levels at the Far Field Limit and Beyond
    In the far field region, the power is distributed in a pattern of 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)
    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 = PDffx 1585/G                                                         0.0112 mW/cm²

    Evaluation:
    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, off axis gain reduction techniques may be used to further reduce
    the power density levels.



8   Off-Axis Power Density Levels at 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 near field main beam power
    density. This may be calculated as follows:
                PDnf(off-axis) = PDnf/100 =                                                         0.0158 mW/cm²



9   Region Between the Feed Horn and Reflector/Sub-Reflector
    Transmissions from the feed horn are directed toward the main reflector or the sub-reflector depending on the type
    of antenna (prime focus, Gregorian or Cassegrain). The transmission is confined within a conical shape defined by
    the feed horn. The energy between the feedhorn and the reflector/sub-reflector is assumed to be in excess of any
    limit for permissible exposure. This region is not accessible to the general public, and operators and technicians
    should be suitable trained and procedures in place to preclude access to this region during active transmission.


10   Evaluation of Safe Occupancy Area in Front of the Antenna
     The distance (L) from a vertical axis passing through the dish center to a safe off-axis point in front of the antenna
     can be determined based on the dish diameter. Assuming a flat terrain and a point on the horizontal plane with the
     center point of the antenna, the relationship is determined by the following formula:
                L = (D/sin a) + (2h - D - 2)/(2 tan a)
      Where:    a = minimum elevation angle of antenna
                D = Dish diameter in meters
                h = Maximum height of object to be cleared, meters
     For distances equal to or greater than determined by the equation above, the radiation hazard will be below safe
     levels
        For:    D=                                                           6.1 meters
                h=                                                             3 meters
     Safe distance for the following elevation angles (a):
                           a - Elevation Angle (degrees)              L - Safe Distance

11   Mitigation Analysis
     Mitigation of accessibility to hazardous regions may take several forms depending on the antenna application and
     location. In instances such as mobile applications, the antenna may be located such that the hazardous region is not
     accessible during operation. An example may be in a mobile configuration where the antenna is located on top of a
     vehicle during operation. In other fixed installation instances the hazardous area may be fenced off to prevent
     access. In areas where only operators and technicians have access, training in safeguards and proper markings of
     hazardous areas may be sufficient. This analysis tool is designed to identify the hazardous exposure regions around
     an operating antenna system in accordance with the defined power density limits in CFR 47, part 1.1310 and OET
     bulletin 65.

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 that 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-receive earth station.
