WARNING: Any antennas placed outdoors must be properly grounded. Use extreme 
caution when installing antennas and follow all instructions included with the antennas. 
 
Table 1 below provides the maximum output power settings for FreeWave transceivers at given 
antenna gain (10 dB and 6 dB Yagi antennas are given as an example) and cable loss 
combinations. Please note that it is the installer’s responsibility to ensure that the emission 
limits are not exceeded

.

Table 2 below shows how the RFXmitPower settings on the radio correspond to the EIRP of the 
transceiver-cable-antenna combination for a 10dB Yagi antenna at different cable loss values.
