Antenna Installation
Antennas must be professionally installed on a fixed, mounted, and permanent structure to satisfy RF
exposure requirements.
exposure requirements.
Warning! Any antenna placed outdoors must be properly grounded. Use extreme
caution when installing antennas and follow all manufacturer instructions included with
the antenna.

Per FCC regulations, any antenna used with FreeWave transceivers must be an approved antenna that has
comparable performance parameters. For more information about approved antennas, see

Cable Loss and Transmit Power Settings
The Transmit Power parameter is the output power of the transceiver. The transceiver output power level
must be set to satisfy maximum Equivalent Isotropically Radiated Power (EIRP) requirements in the country
in which the installation exists.
must be set to satisfy maximum Equivalent Isotropically Radiated Power (EIRP) requirements in the country
in which the installation exists.
When setting up the network, consider the power gain that an antenna may add, and the power loss through
cabling. Adjust the Transmit Power on the transceiver to ensure that you do not exceed the maximum EIRP
for the regulating body where the installation exists. Use the tables below to determine the correct Transmit
Power parameter setting for each transceiver in the network.

Important:
The information in this section discusses FCC and ETSI maximum EIRP
regulations. Ensure your installation meets the maximum EIRP requirements for the
country in which you are installing transceivers. It remains the installer's responsibility
to ensure that an installation is within EIRP emission limits.
