2.4 Order of precedence. In the event of a conflict between the text of this document and the references cited herein (except for
related associated specifications or specification sheets), the text of this document takes precedence. Nothing in this document,
however, supersedes applicable laws and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
3.1 Specification sheets. The individual item requirements shall be as specified herein and in accordance with the applicable
specification sheets. In the event of any conflict between requirements of this specification and the specification sheet, the latter
shall govern.
3.2 First article. This specification makes provisions for first article testing. Antennas furnished under this specification shall be
a product which has been tested in accordance with the first article tests prescribed herein (see 4.3) and approved by the
responsible acquiring activity (see 6.4).
3.3 Materials and finish. Materials shall be as specified herein (see 3.1). Where a definite material is not specified, materials
and finish used on construction of the antenna shall resist erosion of surfaces due to action of rain, ice crystals, and other impinging
particles at velocities as specified in accordance with applicable specification sheet (see 3.1). Acceptance or approval of any
constituent material shall not be construed as a guaranty of acceptance of the finished product.
3.3.1 Nonflammable material. Materials shall be nonflammable when tested by accepted industry methods.
3.3.2 Fungus inert material. The antenna materials shall be fungus inert or resistant.
3.3.3 Pure tin. The use of pure tin as an underplate or final finish is prohibited both internally and externally. Tin content of the
amplifier components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3 percent lead, by
mass (see 6.7).
3.4 Design and construction. Antenna shall be of design and physical dimensions specified (see 3.1).
3.4.1 Connectors. The antenna connectors shall be designed to accommodate plug UG-59( )/U and meet the interface
requirements in accordance with MIL-DTL-3643. The test probe connector shall be designed to accommodate plug P/N
M39012/16-0001 in accordance with MIL-PRF-39012.
3.4.2 Temperature operating range. The antenna shall operate without electrical or mechanical deterioration over the specified
temperature range in accordance with the application specification sheet (see 3.1).
3.4.3 Seal (see 4.6). All openings of the antenna cavity shall be sealed to prevent air leakage during all changes in surface
pressure encountered in air operations between pressure altitudes of 0 to 70,000 feet.
3.4.4 Resistance to solvents (see 4.7). All materials used in construction shall withstand direct contact with aromatic fuels and
hydraulic liquid without causing electrical or mechanical deterioration.
3.5 Environmental requirements. The antenna shall withstand the environmental tests of 4.5.7 without mechanical or electrical
deterioration. Following each environmental test, the antennas shall meet the electrical requirements specified.
3.5.1 High temperature. When tested as specified in 4.5.7.7, the antenna shall meet the electrical requirements of 3.6.2, 3.6.3
and 3.6.4.
3.5.2 Temperature altitude. When tested as specified in 4.5.7.1, the antenna shall meet the electrical requirements of 3.6.2
through 3.6.4.
3.5.3 Shock. When tested as specified in 4.5.7.2, the antenna shall meet the electrical requirements of 3.6.2 through 3.6.4.
