SYSTEM DESCRIPTION AND INSTALLATION MANUAL
JetWave™ System
© Honeywell International Inc. Do not copy without express permission of Honeywell.
(1) Introduction
The TMA assembly is to be installed on the top of the tail empennage of the aircraft. For the
JetWave™ system to correct
ly point the antenna, the installation offsets should not exceed
more than 1 degree off heading, pitch or roll with respect to principle axis of aircraft.
Depending on the airframe, the LRUs and assemblies that follow would be installed outside
aircraft fuselage as part of tail mount OAE:
•The TMA assembly
• KRFU LRU
• Radome assembly
• Radome fairing (if required).
The exact install location of the TMA asse
mbly and KRFU is
airframe specific.
The radome, radome fairing (if required), and TMA/KRFU to aircraft interface brackets are
airframe specific and the details are not covered in this manual.
Consideration must be given when deciding where to install the antenna on the factors that
follow:
• Other antennas or equipment that may block the JetWave™ antenna
from being able to
see the satellite
• The JetWave™ antenna blocking other antennas
• Potential interference by the JetWave™ transmitted
signal degrad
ing the received signal
of other aircraft RF systems
• Potential interference by other RF systems degrading the received signal of the
JetWave™
system.
The TMA complies with form as defined in JetWave™ TMA outline and installation drawing
in Figure
2-30, the KRFU outline and installation drawing Figure 2-28, and the interconnect
diagram in Figure 2-33.
Refer to Table 2-4 for special tools, fixtures, and equipment for the TMA installation.
Antenna clearance for sweep volume is 12 inches (304.8 mm) minimum around dish sweep
area.
(2) TMA Installation General
Before installing any components
or cabling, read all notes on drawings and read all
installatio
n procedures.
