TX power selection with 2dBi antenna gain for ETSI compliance

If I want to be compliant for EU ETSI (868MHz) max 25mW Tx power using SX1276 chip and a stick antenna with +2 dBi gain, what TX power level should I use?

Right now I use 14dBm setting but I’m not sure if you have to reduce it, if using the antenna?

Thanks in advance!

The radio can output at +14 dBm with the +2 dBi antenna for total EIRP +16 dBm remaining below the 25 mW (+14 dBm ERP) limit.

EIRP = ERP + 2.15 dBm
