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!
– Does not include the receiver
