FUTABA 12K Instruction Manual page 33

The R3008SB has two antennas. In order to maximize signal reception and promote safe
modeling Futaba has adopted a diversity antenna system. This allows the receiver to obtain RF
Antenna
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.

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.
*Must be kept as straight as possible.

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
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.
