Information for Professional Installers
The product must be installed professionally, and the transmit power of the system must be adjusted by the professional
installers to ensure that the system EIRP is in compliance with the limit specified by the regulatory authority of the country
of application.
See the following sections for more information:
• Adjusting Tx Output Power
• Antenna Types and Maximum Gain
• Separation Distance
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
