Antenna Recommendations

Note: Do not remove the diversity antenna. The diversity antenna helps the gateway
achieve the maximum network coverage. The gateway works without one installed, but
with reduced network coverage.
Note: If the antennas are located far away from the gateway, keep the cables as short as
possible to prevent the loss of antenna gain.
Warning:
The antenna should not exceed the maximum gain specified in
Antenna Gain (Gain D'antenne Maximal)
as those requiring long lengths of cable and/or multiple connections), you must follow the
maximum dBi gain guidelines specified by the radio communications regulations of the
Federal Communications Commission (FCC) or Industry Canada or your country's
regulatory body (if used outside the US). Also see
