Hello dear Folks!

Google went confused with my above question, so I'm addressing my question here:
I have multiple SIM5320 GSM modules. Each of them have antenna pin so micro-strip PCB or discrete 50ohm antenna can be connected. See reference documentation, section 4.3 (page 54-55).
In my application I'm using 4 such modules, but I want to connect all of them to a single external single pole antenna (stick antenna).
If you have any design idea, I really appreciate to share with me!

Thank you!
