FCC Form 312 Exhibit 2 EXHIBIT REGARDING NOTIFICATION OF NEW ANTENNAS (CALL SIGN KA399) Telesat Network Services, Inc. (“Telesat”) is filing the instant application to notify the International Bureau that it has added three new antenna types – SeaTel USAT 24, SeaTel 4009, and SeaTel 6009 – to its existing authorization for Ku-band transmit/receive earth station and earth stations on vessels (“ESV”) operations under Call Sign KA399. Telesat notes that all three antenna types have been determined to be electrically and technically identical to their predecessor models – SeaTel 2406, SeaTel 4006, and SeaTel 6006. Cobham SATCOM, manufacturer of the antennas, has ceased producing the earlier models and, by way of the attached declaration, certifies that the new models have identical radiofrequency performance to those predecessor models. The Bureau had previously granted Telesat authority to operate the 2406, 4006, and 6006 models. 1 Telesat recognizes that it could add the antennas to its operations without notification, consistent with 25.118(b) of the Commission’s rules, which permits activation of replacement equipment that is electrically identical to the existing equipment. 2 However, out of an abundance of caution and because Telesat will continue to operate the predecessor antennas for the foreseeable future in addition to these new replacement antennas, it is also submitting the instant notification to add those antenna models to its current authorization. 1 Telesat’s authority to operate the antennas under its Call Sign KA399 is as follows: the 4006 authority was added under File No. SES-MOD-20090206-00154 (granted Jan. 4, 2010); the 2406 and 6006 authority was added under File No. SES-MOD-20100513-00590 (granted Feb. 8, 2011). 2 47 C.F.R. § 25.118(b).
