450i Transmit Power Specifications

The radio's web gui claims the Tx power can go up to 27 dBm. Can full 8X modulation be achieved at this power level? 

If it can't, where can I find the specs for modulation vs tx power?

Thanks!

I've poured over the 450 user guide and cannot find anything that indicates if 27dBm is only available for lower moduation levels. Maybe someone from Cambium can chime in...

From the manual:

Transmit Power Range 40 dB dynamic range (to EIRP limit by region) (1 dB step)

Maximum Transmit Power +27 dBm combined output (for 5 GHz)
