Receiver's Antenna Installation
You will note that the R6208SB differs in appearance from the standard Futaba receiver. This receiver
incorporate two separate antennas into their design which enables them to receive the radio frequency
transmission at two different locations.

Futaba's dual antenna diversity then seamlessly selects the best signal reception between these antennas
to ensure that there is no loss of signal.
To obtain the best results of the diversity
function, please refer to the following instructions:
1. The two antennas must be kept as straight as
possible. Otherwise it will reduce the effective
range.
2. The two antennas should be placed at 90
degrees to each other.
This is not a critical figure, but the most
important thing is to keep the antennas
away from each other as much as possible.
Larger models can have large metal objects
that can attenuate the RF signal. In this case
the antennas should be placed at both
sides of the model. Then the best RF signal
condition is obtained at any flying attitude.
3. The antennas must be kept away from
conductive materials, such as metal, carbon
and fuel tank by at least a half inch. The
coaxial part of the antennas does not need
to follow these guidelines, but do not bend it
in a tight radius.
4. Keep the antennas away from the motor,
ESC, and other noise sources as much as
possible.
*The two antennas should be placed at 90 degrees to each other.
*The main purpose of the photo demonstrates how the antenna should be placed.
*Receiver Vibration and Waterproofing: The receiver contains precision electronic parts. Be sure to avoid vibration,
shock, and temperature extremes. For protection, wrap the receiver in foam rubber or other vibration-absorbing
materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag and securing the open end of the
bag with a rubber band before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver,
you may experience intermittent operation or a crash. If in doubt, return the receiver to our service center for service.
