CNI22 Swept Blade Antenna

The true innovation, however, is the use of a one-piece metal casting for the base and antenna leading edge, which greatly increases side load strength, erosion resistance, and service life. Life cycle operating costs are reduced. Severe vibration and buffeting environments are accommodated by this design which is capable of high G resonance dwell. An additional benefit of the swept-back leading edge is radar signature reduction when compared to previous vertical blade antennas.

Several mounting footprint options are available for aircraft including the B-1B, F-15, F-16, and F-111.

Features:

Metal leading edge
Dual Frequency
Lo RCS
Erosion Resistant
