Ok, based on that I think your right antenna (or cable) has an issue. It seems that the problem was originally the left (Primary) antenna which explains the RTK status of 2 and 5 and now it’s 4 (normal). The L2 is now zero and the secondary antenna reports the L2 statistics. Your HDOP is considerably higher now too. I would suggest support send you 2 new RTK antennas and yes it is just a simple screw them on. I don’t know what is normal L2 numbers for you, maybe 7 is. But that is low. That’s why I’m saying send or order 2 antennas.
