Hello Quectel team,

I accidentally broke one of the antenna base connectors on my RM551E-GL modem (see attached photo). I believe it’s the MHF4 (U.FL) surface-mount type.

Before I order replacements, could you please confirm if the connector shown below is correct and compatible?

“10PCS 4th Generation MHF4 Male Plug Antenna Base U.FL SMT PCB RF Coaxial WiFi Connector”
I just found this on AliExpress:
