M.2 Cellular Antenna Placement

Correct antenna placement is critical to ensure proper functionality of the M.2 Cellular expansion card. Two antennas (main and auxiliary) are required for each card and should be separated to improve signal quality.

Single Card Configuration

For single card applications, antenna placement is as follows:

Channel A

Main in slot 1
Auxiliary in slot 6

The A and B channel strength indicators do not directly correspond to the antenna slot positions (Slots 4-6 are not specifically reserved for channel B).

Dual Card Configuration

For dual card applications, four antennas (2 main and 2 auxiliary) will be used. Antenna placement is as follows:

Channel A

Main in slot 1
Auxiliary in slot 4

Channel B

Main in slot 3
Auxiliary in slot 6
