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 FGRPlus FreeWave 
transceivers at given antenna gain (12.15 dBi and 8.15 dBi Yagi antennas are given as an 
example) and cable loss combinations. 

 
NOTE:  It is the installer’s responsibility to ensure that the emission limits are not 

exceeded
