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 FGR-HT FreeWave
transceivers at given antenna gain (10 dB and 6 dB 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
.
Table 2 below shows how the RFXmitPower settings on the radio correspond to the EIRP of
the transceiver-cable-antenna combination for the 10 dB Yagi antenna at different cable loss
values.
Shaded area indicates combinations where EIRP limitations exceed FCC regulations
and RF Xmit Power must be reduced.
