Hello Mr. Volek,



You filed a Receive Only Earth Station Registration Application stated above on August 22, 2014, this is a C—band and you
must submit a Frequency Coordination attachment Data sheet with your FCC For 312 pursuant with the FCC Rules part
25:131, so therefore your application is unaccepted as filed? Please submit the requested Information for this filing in
order to process your application.

Thank you,

                                         Receive/Only Earth Station



This report presents the results of a preliminary interference analysis for a proposed C—band receive/only
earth station site. The site was selected by SDN Communications and is located in Sioux Falls, South
Dakota.


The earth station was analyzed for reception of analog and digital traffic from all domestic satellites located
in the satellite arc from 60 degrees to 143 degrees West Longitude. Operation on all transponders in the
3700 to 4200 MHz frequency band was investigated.


This analysis was performed considering a 4.5 meter antenna. The long term interference objective is —156
dBW/ 1 MHz.


The preliminary analysis is meant to provide an overview of potential interference at this location and to
recommend a course of future action.


                                                   SECTION 2

Section 1 presents the introduction describing the system characteristics including site location, system
name, type reception, satellite arc, frequency band considered, type antenna, and interference objectives.


Section 2 describes the contents of this report.


Section 3 presents the site analysis data sheet. This sheet includes the system location data, site analysis
conclusions, and a summary of the analysis with recommendations.


Table 3.1—1 summarizes the results of the preliminary analysis, with predicted over—the—horizon (O—H)
losses calculated for the various potential interference cases. The columns, reading from left to right,
represent the following data:


       1. Path                 —       Interference source and transmission path.

       2. Band                 —       The frequency band in GHz.

       3. Azimuth              —       Azimuth from the earth station toward the interference

       4. Distance             —       Distance to interference source (kilometers).

       5. LOS Margin           —       Interference margin in dB, on a line—of—sight (LOS) basis,
                                       i.e., additional isolation required to meet objective (no
                                       blockage assumed).

       6. O—H Loss             —       Estimated over—the—horizon loss in dB (predictions consider
                                       antenna height and path length, no detailed terrain data used).

       7. Estimated            —       Considering O—H Loss, difference Margin between LOS
                                       margin and O—H loss in dB (negative values indicate
                                       interference is unlikely).

The cases marked with an asterisk are the cases posing the greatest interference problems.


Table 3.1—2 tabulates all transponders that would be affected by terrestrial stations in the 4 GHz
frequency band. The columns reading from left to right present the following data:


               1. Terrestrial                Interference source and Transmission path.

                                             interference source (bearing measured from True North).

               4. Distance                   Distance to interference source (Kilometers).

               5. Loss Required              The amount of loss in dB, required to reduce the
                  (Long Term)                interference levels to meet the 20% objective.

               6. Loss Required              The amount of loss in dB, required to reduce the
                  (Short Term)               interference levels to meet the .01% objective.

               7. Affected                   The transponders that are affected by the interfering
                   Transponders              source. The transponders are numbered 1 — 24 from left to
                                             right.


Section 4 summarizes the data pertinent to the proposed receive/only earth station.


Table 4.1—1 contains the operational parameters of the proposed earth station.


Table 4.1—2 lists the azimuth and elevation data for the satellite arc, including those satellites within that
arc.



Figure 4.1—1 indicates the location of the proposed receive/only earth station. This location should be
verified, and if it is not the desired site, Comsearch should be notified immediately so that the
precise location can be plotted and analyzed.

7.   Summary of Results

Conclusions

The preliminary analysis did not identify any potential terrestrial interference conflicts within the
coordination contours of this site.

Recommendations

Based on the results of the preliminary analysis, it is recommended this site be prior coordinated with the
common carriers as the first step toward FCC registration.

It should be noted that this analysis considers the 4 GHz microwave environment and does not include
potential interference from sources outside the 4 GHz band. ( Radar Altimeters, Radar Detectors, Cellular
Phone, ect.)
