Adjusting Tx Output Power
Use the following formula in combination with the table of EIRP limits to calculate system transmit power (based on EIRP
limits):
Tx Power Allowed (dBm)
= EIRP Limit (dBm) + CL (dB) – G (dB)
where:
Tx Power = Output power measured at the antenna input
EIRP Limit = EIRP limits specified below
CL = Coax cable loss including loss of connectors
G = Antenna Gain
* For EU countries, 5.15-5.35 GHz are for indoor use only.
Antenna Types and Maximum Gain
Professional installers should select only the antenna types listed in the following table, with gain not exceeding the listed
maximum gain for each type.
