KA 815 Antenna Installation Considerations

A. Antenna Location
The following antenna location procedure is provided for guidance pur-
poses and to outline a method of achieving certifiable system perfor-
mance.
The KMH 880/KTA 870 System uses a top-mounted directional antenna and
either a bottom-mounted directional or an L-band omni-directional antenna.
Refer to directional antenna outline drawings in Figure 2-3. Mounting the
directional antenna MUST include the appropriate doubler plate.The install-
ing agency is required to fabricate the doubler plate for the antenna installa-
tions.
The L-band omni-directional has not been tested for the direct effects of lightning
and the installer (TC or STC applicant) must determine the suitability of the
antenna for the specific installation.
KMH 880/KTA 870 Systems REQUIRE that the antenna installation
guidelines be followed. Adherence to these guidelines will assure that crit-
ical specifications are considered. Optimum bearing accuracy can be
achieved by following these directions.
Antenna locations should be chosen so that both antennas appear to be at
the same range and bearing from the intruder.
The centerline of the top and bottom-mounted TAS Antenna should be
located as close as possible to the aircraft centerline.
The top directional TAS Antenna should be the most forward antenna and as
far forward on the constant radius portion on the fuselage as possible.
