Note
: The AR9000 requires that at least one remote receiver be installed.
Install the main receiver using the same method you would use to install a
conventional receiver in your aircraft. Typically wrap the main receiver in protective
foam and fasten it in place using rubber bands or hook and loop straps. Alternately
in electric or turbine-powered models, it’s acceptable to use thick double-sided
foam tape to fasten the main receiver in place.
Mounting the remote receiver(s) in a different location(s), from the primary receiver,
gives tremendous improvements in path diversity. Essentially each receiver sees a
different RF environment and this is the key to maintaining a solid RF link, even in
aircraft that have substantial conductive materials, (i.e. turbine engines with metal
tail pipes, carbon fiber, tuned pipes, etc.) which can attenuate the signal.
Using double-sided foam tape (servo tape), mount the remote receiver(s) keeping
the remote antenna(s) at least 2 inches (51mm) away from the primary antenna.
Ideally the antennas will be oriented perpendicular to each other, however, we’ve
found this to not be critical. Leads of varying length are available (see table below),
and in sophisticated aircraft we’ve found it best to mount the remote receivers in
different parts of the aircraft, keeping the remote antennas as far away as practical
from any conductive materials.

Installing the AR9000
The AR9000 incorporates dual internal receivers, and one or two remote receivers
offering the security of up to four simultaneous RF links for the ultimate in multi-
path RF security. Two internal receivers are located on the main PC board, while
a third remote receiver must be plugged into one of the antenna ports in order for
the system to operate. Optionally, a second remote antenna can be plugged into
the remaining remote antenna port giving a total of four operational receivers. By
locating these receivers in different locations throughout the aircraft, each receiver
is exposed to its own RF environment, greatly improving path diversity (the ability
of the receiver to see the signal in all conditions).
