Attachment Narrative

This document pretains to SAT-AMD-20120615-00098 for Amended Filing on a Satellite Space Stations filing.

IBFS_SATAMD2012061500098_955487

Amendment1

Spectrum Five LLC (“Spectrum Five”) herein provides requested clarifications and
modifications to a previously filed amendment2 to conform the pending petition for declaratory
ruling seeking U.S. market access for a Netherlands-licensed 17/24 GHz satellite at the nominal
119° W.L. orbital location to the Commission’s new licensing rules and policies.3

The additions and changes to the prior amendment include the following:

(i) the cover sheets in the attachments for each beam have been clearly labeled to show that
they represent the maximum EIRP across the specified off-axis angular range;

(ii) the cover sheets in the attachments for each beam have been clearly labeled to show that
the maximum antenna gain over the specified off-axis angular range can be determined
by subtracting the power into the antenna (from Table I of this document) from the EIRP
plotted;

(iii) new EIRP plots for spot beams 19 and 22 for the +X-axis have been inserted into the
spot beam data, as there was a compilation error in the previous amendment which
mistakenly showed the +X-axis plots for beams 18 and 21 instead; and

(iv) the data summaries shown in this document of the beams have been augmented to show
the maximum value of antenna gain for each of the beams in comparison with the
allowed limit based on the rules, and specific plot file for which this maximum occurs.

The remaining information in Spectrum Five’s pending petition is unchanged and is
incorporated by reference.4

This amendment is provided in response to discussions with the FCC’s International
Bureau technical staff regarding clarifications and modifications to Spectrum Five’s previously
filed amendment, File No. SAT-AMD-20120525-00090 (filed May 25, 2012) (“May 2012
Amendment”).

On May 25, 2012, Spectrum Five filed an amendment to provide clarifications and
reformatting to its December 2011 space path interference amendment. See File No. SAT-AMD-
20111223-00247 (filed Dec. 23, 2011) (“December 2011 Amendment”).
