3. If the maximum transmitter power allowed is less than 30 dBm, use
the
PWR
command (described on Page 42) to set the power accord-
ingly.
For convenience, Table 3 lists several antenna system gains and shows
the maximum allowable power setting of the radio. Note that a gain of
6 dB or less entitles you to operate the radio at full power output—30
dBm (1 watt).
* Many antenna manufacturers rate antenna gain in dBd in their
literature. To convert to dBi, add 2.15 dB.
† Feedline loss varies by cable type and length. To determine the
loss for common lengths of feedline, see Table 2 on Page 13.

INSTALLATION
Figure 12 shows a typical transceiver product shipment, along with an
optional Hand-Held Terminal (HHT). Check the contents against the
packing list secured to the outside of the shipping box. Accessories and
spare parts kits, if any, are wrapped separately. Inspect all items for
signs of damage and save all packing materials for possible re-shipment.
