MIL-DTL-4946E
3.4.2 Antenna mounting. The antenna mounting shall be as specified in AF Drawing 64C3419 for mounting to
antenna mast AB-158/GR.
3.4.3 Input connector. The input connector shall be of HN female series and shall have mating dimensions as
specified in MIL-DTL-3643.
3.4.4 Cable. The cable from the input connector to the radiating elements shall be M17/79-RG218 (unarmored) in
accordance with MIL-DTL-17/79.
3.4.5 Weight. The total weight of the antenna shall not exceed 15 pounds.
3.4.6 Finishing. Before painting, the antenna shall be given a protective finish in accordance with the requirements
of MIL-DTL-14072.
3.4.7 Color. The color of the paint finish applied to the antenna, shall be number 24084 in accordance with FED-
3.5 Performance.
3.5.1 Gain. The gain from 225 through 400 MHz, shall not be less than 0.3 decibels (dB) over that obtained from a
half-wave dipole, tuned to maximum efficiency (see 4.6.3.1).
3.5.2 Voltage standing wave ratio (VSWR). The VSWR over the entire frequency range shall not exceed 2 to 1
with respect to 50 ohms (see 4.6.3.2).
3.5.3 Impedance. Normal impedance of the antenna shall be 50 ohms (see 4.6.3.3).
3.5.4 Radiation pattern. The horizontal radiation pattern shall be omni-directional and shall not vary from circular
by more than 0.5 dB (see 4.6.3.4).
3.5.5 Frequency range. The antenna shall be capable of satisfactory operation without hiatus at any frequency
throughout the 225 through 400 MHz range. Mechanical tuning to operate the antenna at any specified frequency in
this range, after initial manufacturing or factory adjustments, shall not be required (see 4.6.3.5).
3.5.6 Power capability. The antenna shall be capable of satisfactory operation with a radio-frequency (RF) carrier
input of 1 kilowatt, amplitude modulated 100 percent by a 1,000 cycle per second signal (see 4.6.3.6).
3.5.7 Environmental. The antenna shall successfully pass all environmental tests listed in 4.6.4.
3.5.8 Marking. The antenna shall be marked in accordance with MIL-STD-130 with the type designation and
manufacturer s name, on a nameplate fastened to the antenna tube.
3.5.9 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.
3.5.10 Workmanship. Antennas shall be processed in such a manner as to be uniform in quality and all surfaces
shall be free of burrs, die marks, chatter marks, scratches, dirt, grease, scale, splinters, and other defects that will
affect life, serviceability or appearance.
4. VERIFICATION
4.1 Test equipment and inspection facilities. Test equipment and inspection facilities shall be of sufficient
accuracy, quality and quantity to permit performance of the required inspection. The supplier shall establish
calibration of inspection equipment to the satisfaction of the Government.
