Information for Professional Installers

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.
