                            Non‐Routine Antenna Exhibit

      Sistema Universitario Ana G. Mendez (Mendez) is proposing to use a 2.4m General
Dynamics Series 1251 antenna as part of its temporary fixed earth station operation. The
antenna was previously manufactured under the Prodelin name as the Series 1251
antenna; however, General Dynamics acquired Prodelin in 2004 and has continued
manufacturing the same antenna which is now under the General Dynamics name.

       The proposed 2.4m General Dynamics series 1251 antenna radiation pattern
exceeds the values specified in Part 25.209 of the FCC Rules from 1˚ to 1.9˚ (measured at
low, mid and high frequency bands) and in various portions of the frequency band from
100˚ to 175˚.

       Pursuant to the Part 25 Earth Station 5th Report and Order (R&O), the International
Bureau has provided a list of Approved Non‐Routine Earth Station Antennas that have been
previously authorized for operation in the United Stations
(http://www.fcc.gov/ib/sd/nresa/). As detailed in the R&O, earth station applications
proposing to use an antenna on the list are not required to submit radiation plots as an
exhibit with their application. Instead, the applicant is only required to provide an
attachment to its application citing the particular non‐routine earth station antenna they
plan to use and the application file number and call sign of the license in which that type of
antenna was previously approved.

       The Prodelin (now General Dynamics) Service 1251 antenna has been authorized
for use in four other instances:

      Call Sign E080110, File #S‐LIC‐20080519‐00642, Max EIRP Density 24.4 dBW/4kHz
      Call Sign E080170, File #S‐LIC‐20080717‐00949, Max EIRP Density 32 dBW/4kHz
      Call Sign E050042, File #SES‐LIC‐20050218‐00196, Max EIRP Density 30 dBW/4kHz
      Call Sign E120073, File #SES‐LIC‐20120427‐00399, Max EIRP Density 32 dBW/4kHz

        In its instant application for C‐Band temporary earth station operation, Mendez is
proposing to operate at a maximum EIRP density of 31.95 dBW/4 kHz which is slightly less
than the highest authorized value. The applicant also agrees to accept any adjacent
satellite interference in the 4 GHz receive band as a result of the performance of the
antenna. Mendez understands that adjacent satellite interference protection applies only
to the extent specified in Part 25.209 of the Commission's Rules.
