JD 317 N1B is an airborne passive broad band antenna which functions in the frequency range of 30 MHz to 420 MHz for air to air, air to ground, in line of sight communication. The antenna design is such that the total aerodynamic drag due to the protrusion of antenna into the airstream is reduced to minimum. The single piece continuous fibre reinforced epoxy shell is designed to meet the stringent MIL requirements of high performance air crafts.(ALH)

Tests in accordance with MIL 810 F
