Helical Lightweight antenna for multiband GNSS (IP67) L1/L2/E5b

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

– Compatible with all simpleRTK2B boards as well as any other multi band 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.
