Conformal Cavity UHF Satcom Antenna

The 21-60-30 is a conformal cavity backed crossed dipole antenna intended for flush-mount UHF Satcom antenna installation on subsonic and supersonic aircraft.

Although designed for a specific supersonic fighter aircraft, different versions can be produced with alternative contours to suit various types of aircraft, depending upon specific installation circumstances.

This antenna uses an aluminum alloy body with integral mounting flange fitted with a high integrity glass reinforced Radome. Radiation is maximum at zenith (90°) but internal element design ensures coverage down to at least 30°. 

  • Suitable for Mach 2+ aircraft
  • Right Hand Circular Polarized
  • Flush mounting - zero drag
  • Wide Angle coverage
  • Designed to MIL-STD-810 environmental conditions
  • Design can be adapted to different aircraft contours.
