Electrical Installation
A.
General
(1)
If there is a common UAV ground, the Indoor Unit should be electrically cross bonded with less
than or equal to 3.0 milliohms direct current (DC) resistance.
(2)
Only 2 cables are required for operation. One to connect the boxes and the other to connect to
the UAV.
B.
Indoor Unit Installation
(1)
General
– The terminal does not require any calibration by the user/installer.

Physical Connectors
A.
RF Cable
(1)
The Honeywell part number 90600596 will be supplied with the terminal.
(2)
The coax cable is able to handle temperatures between -40°C to 55°C (-40°F to 131°F).
(3)
The cable has a fixed loss requirement and should not be substituted or shortened, or the
