Received this from DJI support today on FB:

It appears that there are 2 different antennas that unfortunatley look identical:  The DJI Focus Unit has a 2.4 GHz antenna (2.415-2.473 GHz) and for those that are using the Focus Expansion Module it uses an identical looking antenna that is for 5.8 GHz.

DJI Support   Mark them. We have requested for clearer markings on them. For now, get a sharpie out and mark up your 5.8GHz antenna.Like · Reply · 48 mins

DJI Support Mike Yes, one is for 2.8, the other 5.8GHz.

Did you had any problem with the newest firmware v1.5 for dji focus?

Has anyone been able to link the Focus to the LB2 system? I have attempted it with the Master, the Slave and have had no luck at all. I am certain that the firmware is all the newest and have used both the liking button as well as the FC menu option but with no luck.
