Our GA-90R is an Active antenna for high-precision GNSS L1/L2/L5 receivers. It’s best for unmanned vehicles, drones, agricultural machinery, lawn mowers, land surveying, and professional field radio equipment... etc. The ASA is boasts excellent weather resistance, with aging resistance over 10 times that of ABS. It also offers excellent high-temperature resistance and a fire rating of UL94-HB or higher. The gooseneck design allows the antenna to be bending flexibly while adjusting. The internal design utilizes a four-arm spiral circular polarization. Please don’t hesitate to email us if you have any questions.
