ARC-182\(V\) radio set. The antenna is an aircraft fuselage mounted blade enclosed element. The antenna is a broadband, fix tuned, exhibits omnidirectional radiation pattern, and is vertically polarized for radiating and receiving radio waves in the 30-88 MHz, 108-174 MHz, and 225-400 MHz communication bands.

MIL-DTL-85670D

3.6.9.1.2 Test method for lightning protection. See the appendix A for test method procedures.

3.7 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally

preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the

operational and maintenance requirements, and promotes economically advantageous life cycle costs.

3.8 Workmanship. Workmanship for the antenna must conform to best manufacturing practices.

4. VERIFICATION

4.1 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities of sufficient

accuracy, quality, and quantity to permit performance of the required inspection shall be established and maintained

by the contractor. Establishment and maintenance of a calibration system to control the accuracy of the measuring

and test equipment shall be in accordance with NCSL-Z540.3 or ISO10012 or approved equivalent by the qualifying

activity.

4.2 Classification of inspections. The inspection requirements specified herein are classified as follows:

Qualification inspection (see 4.4).

Qualification testing (see 4.5).

Conformance inspection (see 4.6).

4.3 Inspection conditions. Unless otherwise specified herein, all inspections shall be performed with conditions

specified as follows:

Room ambient (25�C � 10�C).

Temperature:

Altitude:

Normal ground.

Vibration:

None.

Humidity:

Room ambient up to 90 percent relative humidity.

4.4 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to the

Government (see 6.3) on sample antennas produced with equipment and procedures normally used in production.

4.4.1 Qualification inspection sample. Three antennas, one of each finish as described by 3.4.7, shall be

subjected to the qualification inspection (see table III). The three samples shall be subjected to the tests in table III.

Qualification inspection samples shall first have successfully completed individual tests (see 4.6.1) before being

submitted for qualification testing.

4.4.2 Inspection routine. Sample antennas shall be subjected to qualification inspection consisting of the

qualification tests in 4.5.3.1 through 4.5.4.8. All three sample antennas shall be subjected to the tests of 4.5.3.1

through 4.5.4.8 in the order listed (see table III).

4.4.3 Failures. Any failure incurred shall be reported as soon as possible to the qualifying activity. All failures shall

be analyzed to the extent necessary to determine the root cause of the failure and reported to the qualifying activity.

The adequacy of corrective actions shall be proven by test. Qualification shall not be granted unless corrective

actions are proven by test and implemented in production hardware. Any antenna failure shall be cause for refusal to

grant qualification.
