2550 M Street, NW Suite 300 Washington, DC 20037 www.lmiadvisors.com June 5, 2018 VIA ELECTRONIC FILING Anthony Serafini Experimental Licensing Branch Office of Engineering and Technology Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Re: UltiSat Inc., Call Sign WM9XHN, File No. 0201-EX-ST-2018; Addition of New Antenna Type for Experimental Testing and Demonstration Dear Mr. Serafini: UltiSat Inc. (“UltiSat”), through its representative, hereby notifies the Commission, pursuant to Section 5.77 of the Commission’s Rules, 47 C.F.R. § 5.77, that UltiSat will test and demonstrate an additional Ku-band terminal type pursuant to the above-referenced experimental special temporary authority (“STA”), which authorizes the operation of up to 100 BB45 (45cm) Ku- band aeronautical terminals. UltiSat will operate up to ten (10) BB30 (30cm) Ku-band aeronautical terminals within the same operational envelope and pursuant to the same terms and conditions embodied in the existing experimental STA. UltiSat does not request a change to the total number of authorized terminals. The BB30 terminal, manufactured by Skytech and designed to be mounted on aircraft of various sizes, has been fully certified for aviation safety. UltiSat now seeks to test and demonstrate the terminal for U.S. government applications under its existing experimental authority. The BB30 terminal complies with Section 25.227 of the Commission’s rules governing earth stations aboard aircraft (“ESAAs”),1 although the terminal will be operated for limited testing and demonstration purposes only. UltiSat acknowledges and accepts that the conditions in its existing experimental license will apply to operation of the BB30 terminal, including operation on an unprotected, non-interference basis, and the requirement to immediately cease operations in the event of harmful interference. 1 See 47 C.F.R. § 25.227.

Because the BB30 antenna will operate within the same emissions envelope as the currently authorized BB45 antenna and UltiSat will otherwise conform to the conditions of its existing experimental license, operation of the terminal is consistent with Section 5.77 of the Commission’s Rules, 47 C.F.R. § 5.77. Please do not hesitate to contact the undersigned with any questions you may have regarding this matter. Respectfully submitted, Carlos M. Nalda LMI Advisors, LLC On behalf of UltiSat Inc.
