Description

Waterproof and compact tripleband L1/L2/L5 + L-band helical GNSS antenna, with a weight of only 21 grams, ideal for lightweight applications like drones or portable devices.

Good to know:
– Compatible with all simpleRTK3B boards as well as any other multiband GNSS receiver in the market.
– Helical antennas are ideal for GNSS reception in strange attitudes (not always facing the sky).
– Integrates a SMA-male termination, no cable is needed although you can use our cable extenders
– Be aware that if you plan to use the Pixhawk connector in the simpleRTK3B board, the helical antenna will block it, so you will need a cable extender.
– This product is an alternative to Holybro HANT-X623A antenna

Includes:
– RTK tripleband + L-band external helical GNSS antenna with SMA connector
