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.
