The height of the female MMCX connector when connected to with a right-angle male connector (availabe from MaxStream on antennas or cables) is approximately 0.31 inches above the component side of the module PC board.

The expected loss for the MMCX connector is 0.3dB though we have measured losses as high as 1.3dB when connected. The RPSMA connector option has a consistent 0.3dB loss.
