CompactFlash Card.
If possible, install the KMH 820/KTA 810 in a dry, temperature-controlled area
such as within the passenger compartment of the aircraft. Standard avionics bays
are accepable as well.
If possible, the KMH 820/ KTA 810 should NOT be located in close proximity to
equipment which produce considerable heat.
Locations, which require disassembly of the aircraft to gain access, are less desir-
able.
Any location that is exposed to moisture and/or temperature extremes should be
avoided.
Select a mounting location that allows sufficient clearance at the front of the unit
for connectors and cables.
Do not bundle data lines or antenna cable with any power cables.
No more than 8.0dB signal loss is allowed in the GPS antenna cable run, includ-
ing the antenna splitter, (if used). Refer to Note 5 on the Antenna Interface Draw-
ing and Table 1-13 in Section 1 for information on cable types and lengths.
Mount the unit to provide good electrical bonding to airframe ground. Lightning
strike protection and RF susceptibility and emission characteristics depend on
good electrical grounding of the unit and cable shield returns.
Refer to Figures 2-11 and 2-12 for TNC connector assembly guidelines.
The KMH 820/KTA 810 will need to interface to the aircraft audio sys-
tem, aircraft DC power, panel mounted warning lamps and switches, a
source of barometric altitude (usually an encoding altimeter or blind
encoder), a GPS antenna and a panel mounted display.
