Receiver's Antenna Installation
The FMR-03 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 signals on both antennas and
fly problem-free.
To obtain the best results of the diversity

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.
*The two antennas should be placed at 90 degrees to each other.
*The illustration demonstrates how the antenna should be placed.
*Install in a way that makes sure that the 2 antennas won't touch the ground. When an antenna touches the ground, there
is danger which becomes control impossibility.
*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 effect 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.
Antenna don't touch the ground.
