4.2.2. GC864-QUAD V2 Antenna Connector
The GC864-QUAD V2 module is equipped with a 50 ohm RF
connector from Murata, GSC type P/N MM9329-2700B.
The counterpart suitable is Murata MXTK92 Type or MXTK88 Type.
Moreover, the GC864-QUAD V2 has the antenna pads on the back
side of the PCB. This allows the manual soldering of the
coaxial cable directly on the back side of the PCB. However,
the soldering is not an advisable solution for a reliable
connection of the antenna.
