Antenna Installation Hazards and Notes
Be sure to keep all system s and antennas clear of power lines
.
Permanent equipm ent dam age and severe shock injury or death can
occur if the system contacts power lines.
Contact Futaba before connecting a ny antenna not provided by Futaba
specifically for the FDP02TJ010.
Attaching any non-authorized
antenna may be in violation of FCC regulations.
Before each use, verify that the an tenna (and antenna cable, if used) is
securely attached and in good con dition. A loose antenn a or cable
may severely reduce the operating range of the system.
The FDP02TJ010 operates at frequencies in the 2.4 GHz band.
These frequencies are more directi onal than lower frequencies and are
easily reflected.
If there are m etal structures nearby, the effective
range m ay be shortened or the dir ectional properties m ay be further
narrowed.
To help avoid this, mount th e antenna as far away as
possible from surrounding metallic structures.
Multipath p roblems occur easily at frequencies in the 2.4 GHz band.
When multipath problems are pres ent, moving the an tenna around 10
cm may result in improved communication or, conversely, worsened or
complete loss of communication.
Futaba recomm ends that the
mounting position of the antenna be dete rmined
after
testing and
verifying optimal communication conditions.
When installing multiple FDP02TJ010 that will use different frequency
groups in the same area, FDP02TJ010’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 inform ation about antenna separation when
using the FDP02TJ010 and other wireless products in the same area.
