#Would you use an internal PCB Antenna over an External Antenna for a Zigbee coordinator?

Hi all, I’m (TubesZB) debating about moving to an EFR32MG24 module with no external antenna port, instead it has a PCB antenna. Benefits are a lower cost even factoring in potentially new tariffs coming. In testing the PCB antenna showed about 1-2 dBi difference when measuring from about 30 ft / 9m. And a customer in the field has had no issues

SiLabs MGM24 module on the right (Channel 20) with external antenna. Alternative EFR32MG24 module on the left with PCB antenna.

Also appreciate that a zigbee network is not a spoke (coordinator) and branches only. it is a mesh, so a well constructed mesh with multiple mains powered routing devices can easily expand range and coverage than any one coordinator no matter the antenna.
