Hi,
I riped a cable of the IOT 20g antenna and already got it open to see that the cable is actualy part of the black inlet block an runs into some kind of crimp connector that is a UMTCm u.fl at the end.
By any change does peplink sell the cable/block as spare or does anyone know if there a such crimp bulkheads.
Internally then it’s just small u.fl end anyway and one cable that goes to the GPS module which I can solder or ignore it as we don’t use it anyway, no need for gps 
Regards
Holger
