• Any significant metallic conductive components

• High-vibration areas

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 offers remote

receiver extensions ranging 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 the 3 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.

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 polarization. This allows the greatest exposed

visual cross section of the antennas from all aircraft orientations. 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.
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 batteries

• Ignition switches

• Engines

• ECU’s pumps

• Electric motors

• Receiver batteries
