Includes:
– RTK multiband external helical GNSS antenna with SMA connector

External multiband L1/L2/E5b helical GNSS antenna, with a weight below 18 grams, ideal for lightweight applications like drones.

Good to know:
– Compatible with all simpleRTK2B 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 simpleRTK2B board, the helical antenna will block it, so you will need a cable extender.
