• 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 degrading 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 defined in JetWave™ TMA outline and installation drawing in Figure
4-30, the KRFU outline and installation drawing Figure 4-27 thru Figure 4-29, and the interconnect
diagram in Figure 4-34.
Refer to Table 4-8 for special tools, fixtures, and equipment for the TMA installation.
Antenna clearance for swept volume is 12 inches (304.8 mm) minimum around dish sweep
area.
B. TMA Installation General
Before installing any components or cabling, read all notes on drawings and read all inst
allation
procedures.
The installer must select the appropriate gauge of wire as specified in the TMA interconnection
diagram in Figure 4-34 for power and control connections. Interconnect cables must be routed
away from sources of potential electromagnetic interference.
The screws used to attach the waveguide flange to the underside of the TMA must not protrude
more than 0.20 inches (0.508 cm) into the TMA base as indicated in the TMA outline and installation
drawing. Refer to Figure 4-29, Note 15.
C. Advisories
The JetWave™ TMA and the KRFU subsystems include components that radiate RF and
microwave emission
s in the band between 29.0 and 30.0 GHz.
All service technicians and operators should be informed of the potential hazards of RF and
microwave radiation. When installing and servicing equipment, exercise the safety precautions that
follow.
