GNSS helix antennas HA-201 seem to be the exact ones Yarbo ships but this is not why I ordered. I ordered the ones above. Be VERY careful, some look identical but are not active or are not L2 compatible. They need to be Dual-band L1/L2 , Gain around 32 dB (the ones in the link are 35 dB but it is fine.
Again, be very careful that you pick the correct specs since they all look very similar. Be sure you can return them if they don’t work.
