Harxon HX-CA3603A GNSS Aviation Antenna


GPS L1 + GLONASS L1 + BeiDou B1 with 36dB Gain



The Harxon HX-CA3603A GNSS aviation antenna features a multi-point feed to achieve greater phase center stability. It improves measurement accuracy and provides better positioning.

The ability to receive low elevation signals with high gain makes the HX-CA3603A a suitable choice for tracking visible satellites and providing stable GNSS data under different flight attitudes.

The antenna LNA features excellent out-of-band rejection performance providing the stability and reliability of GNSS signals.

The dimensions of the HX-CA3603A are only 90 mm x 27.5 mm (without connector) with a light weight of 13 grams, which makes it ideal to be used with professional drones, unmanned vessels or where high precision operations are needed. The IP67 ruggedized cover can protect the antenna from dust and water with its patented waterproof and breathable design.
