Mounting the Remote Receivers
Antenna Polarization
For optimum RF link performance, it's important that the remote antennas be
mounted in an orientation that allows for the best possible signal reception when
the aircraft is at all possible attitudes and positions. This is known as antenna po-
larization. This allows the greatest exposed visual cross-section of the antennas
from all aircraft orientations. If three antennas are used, it is recommended that
one antenna be mounted vertically, one horizontally in-line with the fuselage and
one horizontally perpendicular to the fuselage (see illustrations on pages 11-12).
This covers the X,Y and Z axis offering superb cross-section visibility in all aircraft
orientations. An optional fourth antenna can be added at an intermediate angle
offering even greater RF link security and system redundancy.
Locating the Remote Receivers
While Spektrum 2.4GHz systems are far more resistant to interference caused
from internal RF generating sources, the remote receivers should be mounted as
far away as practical (typically 4" or greater if possible) from the following:
• Ignition systems
• Ignition switches
• ECU pumps
• Receiver batteries
• Metal bypass tubes • High-temperature components like exhaust systems
• High-vibration areas • Any significant metallic conductive components
The remote antennas should be mounted a minimum of at least 2" apart from
each other as greater antenna separation gives improved path diversity (RF link
performance) in critical environments. In large aircraft where space is not an
issue, it is highly recommended that the antennas be mounted throughout the
aircraft as illustrated. Spektrum remote receiver extensions range from 6" to 36"
allowing the receivers to be mounted in the most optimum locations throughout
the aircraft.
Using double-sided foam tape and tie wraps, mount a minimum of three and up
to four remote receivers in your aircraft as per the illustrations and plug them into
the receiver ports.
The following are illustrations of typically recommended installations. Note the
remote receiver orientation.
• Ignition batteries
• Engines
• Electric motors
• Fuel tanks
