D. PLANNING THE ANTENNA INSTALLATION
Many factors are important when planning an optimum antenna
installation for use with a radar altimeter system. Careful
planning and attention to detail are absolutely necessary. Failure
to install the antennas correctly will cause degradation in system
performance.
• Antennas should be mounted near point of aircraft rotation. This
reduces the effect of pitch and roll attitude in altitude read-
ings during approach and landing.
• Antennas must be mounted close enough to the R/T so that the an-
tenna cable length does not decrease system sensitivity. Refer
to TABLE 1-2 CABLE INSTALLATIONS for minimum and maximum lengths
and minimum bend radii for cables.
