Another Hardware Tear Down for you :)
Note the UFL connectors for the antenna..... re-boxing an M900 anyone..?
Also the unusual Antenna array... someone care to enlighten us?


The reason there is only one RP-SMA connector is you have three Antenna options in the software.
1. Internal 2x2,
2. 1x1 External,
3. Internal + External = 2x2
So you cannot do 2x2 External





Dual polarity Patch Antenna
Simple elegant design the two feeds are 90 degrees out of phase
