Aircraft antenna JH 311 N1B

for dronesVHFomnidirectional

JH 311 N1B is an Airborne Very High Frequency (VHF) phase matched blade antenna designed to be used as DF arrays with DF systems and with airport systems. These antennas are designed as low drag blade antennas suited for fixed wing air crafts, helicopters and UAVs. The fiber reinforced single piece epoxy antenna shell is designed to meet the stringent MIL requirements. The unique electrical design of the antenna ensures superior phase matching across the band. These antennas can also be individually used with communication systems and offer excellent omni-directional coverage.
