Receiver Installation
The AR6210 incorporates dual receivers, offering the security of dual path RF redundancy. An 

internal receiver is located on the main PC board, while a second external receiver is attached to 

the main board with a 6-inch extension. By locating these receivers in slightly different locations in 

the aircraft, each receiver is exposed to its own RF environment, greatly improving path diversity 

(the ability for the receiver to see the signal in all conditions). 
Antenna Polarization
For optimum RF link performance it’s important that the antennas be mounted in an orientation 

that allows for the best possible signal reception when the aircraft is in all possible attitudes and 

positions. This is known as antenna polarization. The antennas should be oriented perpendicular to 

each other; typically vertical and horizontal and at different angles (see Receiver Installation below). 

The remote receiver antenna should be mounted in a position perpendicular at least 2 inches away 

from the main receiver’s antenna using double-sided foam tape. 

Receiver Installation in Aircraft
In gas and glow aircraft 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 airplanes 

or helicopters, it’s acceptable to use thick double-sided foam tape to fasten the main receiver in 

place. Mounting this remote receiver in a slightly different location, even just inches away from the 

primary receivers, gives tremendous improvements in path diversity. Essentially, each receiver sees 

a different RF environment and this is key to maintaining a solid RF link, even in aircraft that have 

substantial conductive materials (e.g. larger gas engines, carbon fiber, pipes, etc.), which can weaken 

the signal. Using servo tape, mount the remote receiver keeping the remote antennas at least 2 inches 

away from the primary antennas. Ideally, the antennas will be oriented perpendicularly to each other. 

In airplanes, we’ve found it best to mount the primary receiver in the center of the fuselage on the 

servo tray and to mount the remote receiver to the side of the fuselage or in the turtle deck. 

In helicopters, there is generally enough room on the servo tray to achieve the necessary separation.  

If necessary a mount can be fashioned using clear plastic to mount the external receiver.
