EXHIBIT No. 1 PAGE 1 OF 7 RTEX Taking the “SEARCH” Out of Search and Rescue Federal Communications Commission Experimental Radio Service P.O. Box 358320 Pittsburgh, PA 15251-5320 Exhibit No. 1 The “Exhibit Information” section of the electronic FCC Form 442 asks for a narrative statement describing in detail the following: a. The complete program of research and experimentation proposed including description of equipment and theory of operation. b. The specific objectives sought to be accomplished. c. How the program of experimentation has a reasonable promise of contribution to the development, extension, expansion, or utilization of the Radio art, or is along lines not already investigated. The FCC request for the above information (a, b, and c) is oriented toward the normal usage of an Experimental License and is not applicable toward the type of usage Artex desires. As per 47CFR5.202(g) stations operating in the Experimental Radio Service will be permitted to conduct operation in the testing of equipment in connection with production or type approval of such equipment. Artex Aircraft Supplies requests an Experimental License to conduct qualification testing of Emergency Locator Transmitters and Antennas as required by the FAA (RTCA DO- 183, Paragraph 2.4.2.2) and FCC 47CFR87.199(b). These tests require an open field site to qualify the transmitter and Antenna. The specific RTCA test procedure can be found at the end of this Exhibit as Appendix A. The qualification procedure requires the ELT system including the Transmitter, Antenna, and Coax Cable to be measured against a reference system. This reference consists of a quarter-wave Mono-Pole Antenna, a 50mW signal source and Coax Cable representative of that used with the ELT system. The reference is set-up on the open field site and power output is measured. The reference system is then removed and the ELT system is substituted. ELT output power is then measured and compared to that of the reference system. If the ELT power is greater than or equal to that of the reference, then the ELT system passes this portion of the qualification test. The RTCA procedure as written has no equivalent bench test that can be used, and the open field test is, therefore, the only way to qualify the ELT system for power output. This test is not conducted during normal production of the ELT, but only when changes are made to the

EXHIBIT No. 1 PAGE 2 OF 7 ELT system requiring confirmation testing of output power. Testing is also conducted if a new component (Transmitter, Antenna, Coax) of the ELT system needs to be qualified. Sincerely, Wendell Neumeyer Engineering Manager EXHIBIT No. 1 PAGE 3 OF 7 APPENDIX A – RTCA POWER OUTPUT TEST PROCEDURE

EXHIBIT No. 1 PAGE 6 OF 7 49 shall be placed on a nonmetallic structure 1.3 meters (4.26 feet) off the ground. The equipment under test shall be located as follows: a. ELT (AF) and (AP) — Place the ELT on or inside the test structure in a configuration representing a typical aircraft installatfon. b. ELT (AD) and (S) — Place the ELT on the ground with supplementary a ground plane. Measurement of radiated or received signals should be made at a point 30 meters (100 feet) from the antenna. At this point, a wooden pole or insulated tripod with a movable horizontal boom should be arranged so that the search antenna can be raised and lowered through an elevation of \/2. The field intensity meter (FIM) and search antenna should be mounted on the end of the boo with its cable lying horizontally ~ on the boom back to the supporting mast. The FIM is placed on a suitable tripod at the foot of the mast. For each frequency measurement, the FIM antenna should be adjusted to the correct length for the frequency involved. Method of Measurement The basic method of measuring of PERP is that of direct substitution as detailed below: a« Place the standard ¥/4 monopole antenna on a ground plane with a minimum dimension of N2 radius, Connect a calibrated signal generator set for the power required in paragraph 2.2.2.5. Account for all losses in transmission lines and impedance mismatch at the antenna to ensure that the transmitted signal is not less than that specified in paragraph 2.2.2.5, "Peak Effective Radiated Power." b. Place the FIM antenna in a vertical position with the lower element tip at least /4 above the ground.
