Antenna Installation Hazards and Notes
Be sure to keep all systems and antennas clear of power lines.
Permanent equipment damage and severe shock injury or death can
occur if the system contacts power lines.
Contact Futaba before connecting any antenna not provided by Futaba
specifically for the FDP03TJ010/020. Attaching any non-authorized
antenna may be in violation of FCC regulations.
Before each use, verify that the antenna (and antenna cable, if used) is
securely attached and in good condition. A loose antenna or cable
may severely reduce the operating range of the system.
The FDP03TJ010/020 operates at frequencies in the 2.4 GHz band.
These frequencies are more directional than lower frequencies and are
easily reflected.
If there are metal structures nearby, the effective
range may be shortened or the directional properties may be further
narrowed.
To help avoid this, mount the antenna as far away as
possible from surrounding metallic structures.
Multipath problems occur easily at frequencies in the 2.4 GHz band.
When multipath problems are present, moving the antenna around 10
cm may result in improved communication or, conversely, worsened or
complete loss of communication.
Futaba recommends that the
mounting position of the antenna be determined
after
testing and
verifying optimal communication conditions.
When installing multiple FDP03TJ010/020 that will use different
frequency groups in the same area, FDP03TJ010/020’s antennas of
different frequency groups must be mounted at least 6 feet (2 meters)
apart. Failure to do so may severely reduce the modem operating range.
Please contact Futaba for information about antenna separation when
using the FDP03TJ010/020 and other wireless products in the same
area.
