or extra so that the wire sticks out slightly and fasten it at 
suitable points. In addition, periodically check the wire 
during daily maintenance.

appearance from the standard Futaba receiver. 
These receivers 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. 
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. 
 
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 
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.
