Special note for 2.4GHz FHSS radio system setup
Since the 2.4GHz have different characteristics than that of the conventional
frequencies, please read this section carefully to enjoy safe ight with the
2.4GHz system.
Receiver’s Antenna installation
The R601FS has two antennas. These antennas have a diversity function to
decrease the chance of a receiving error.
The wavelength of the 2.4GHz is much shorter than that of the conventional
frequencies, it is very susceptible to loss of signal which results in a receiving
error. In order to avoid this phenomenon, the R601FS adopted a diversity
antenna system.
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 gure, 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 ying attitude.
3. The antennas must be kept away from conductive materials, such as metal and
carbon 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 small 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. For actual installation the
receiver must be wrapped with a
sponge or placed with floating material
to protect it from vibration.
