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 models, it’s acceptable to use thick double-sided foam tape to fasten the
main receiver in place.
Mounting the remote receiver in a slightly different place, even just two inches 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, (e.g.,
larger gas engines, carbon fiber, tuned pipes, etc.) which can weaken the signal.
Using double-sided foam tape, (servo tape) mount the remote receiver keeping the
remote antenna at least 2 inches (51mm) away from the primary antenna. Ideally
the antennas will be oriented perpendicular to each other. In airplanes, we’ve found
it best to mount the remote receiver to the side of the fuselage or in the rear turtle
deck.
In helicopters, there is generally enough room on the servo tray to achieve the
necessary separation. If necessary, a mount can be made using clear plastic to
mount the remote antenna as shown below.
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).
