Bias Tee on the S3?


I've got the chance to use a masthead amplifier requiring 5V @ 80mA with my S3 but I've not been able to find any S3 documentation about the specification even though it's listed as having it on two antenna inputs. I assume it's 5V at ????mA?

My other option is to get an external Bias-T +ve inserter and given the high price tag of the S3 would that be a safer option?
