EA31 - 1

UAV GNSS Antenna Dual frequency multi-constellation satellite mode and support L-band Light weight Superior anti-jamming performance Low noise factor Protection level IP67 The EA31 UAV GNSS antenna is a high-performance active 4-wire helical antenna specially supported for GPS L1/L2, BeiDou B1/B2 and L-band. The antenna is designed for application of UAV high-precision satellite navigation and uses parasitic 4-helical technology to achieve dual-frequency coverage, which provides good polarization axial ratio and high efficiency. The EA31 antenna has the characteristic that it is minimally affected by the ground reflecting surfaces. The antenna has excellent filtering and anti-jamming performance, which uses O-ring as seal protection with IP67 level.
