S/C Band Airborne Blade Antenna
2400 to 5900 MHz
The 21-40-37 is a wide frequency S/C band airborne blade antenna designed for fixed and rotary wing aircraft. It is a direct footprint replacement for AT256 UHF Blade antennas.
Electrical design is based on a 2-dimensional, monocone which is of high efficiency and provides nearly omnidirectional azimuthal radiation.
Mechanical design uses an advanced, glass-loaded thermoplastic radome with an integral radiating element, all foamed-in-place for structural and environmental integrity.
The blade is built into a contoured injection moulded base collar and has a centrally mounted, N-type female coaxial connector.
