Special note for 2.4GHz FHSS radio system setup
Receiver ’s Antenna installation
Since the 2.4GHz have different characteristics than that of the conventional
frequencies,
please read this section carefully to enjoy safe flight with the
2.4GHz system.
The MR-600has 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 MR-600adopted 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 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 o btained at any flying 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.
e
The receiver contains precision electronic parts. It is the most delicate radio
component on-board the model and should be protected from vibration,
shock and temperature extremes. To protect the receiver, wrap it in R/C foam
rubber or other vibration-absorbing material. If appropriate, waterproof the
receiver by placing it in a plastic bag and closing the open end with a rubber
band before wrapping it in foam. If moisture enters the receiver, intermittent
operation or a failure may result. Wrapping the receiver in a plastic bag also
protects it from fuel and exhaust residue which, in some models, can work its
way into the fuselage.
