Adjusting Tx Output Power
Use the following formula in combination with the table of EIRP limits in US and EU countries to
calculate system transmit power (based on ERIP limits) of these countries:
Tx Power (dBm) = EIRP Limit (dBm) + FL (dB) – G (dB)
where:
Tx Power = Output power measured at the antenna input
EIRP Limit = EIRP limits specified below
FL = Feeder loss including loss of connectors
G = Antenna Gain
EIRP Limit (dBm)

Antenna Types and Maximum Gain
For devices using external antennas, professional installers should select only the antenna types listed
in the following table, with gain not exceeding the listed maximum gain for each type.
