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 HTplus 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
.
Table 2 below shows how the Transmit Power settings on the radio correspond to the EIRP
of the transceiver-cable-antenna combination for the 12.15 dBi Yagi antenna at different
cable loss values.
Shaded area indicates combinations where EIRP limitations exceed FCC regulations
and RF Xmit Power must be reduced.
