When routing antenna cables, observe the following precautions:
All cable routing should be kept as short as possible and as direct as possible.
Avoid sharp bends.
Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near
power for fluorescent lighting.
Avoid routing cable near ADF antenna cable (allow at least a 12-inch separation).
The table below lists the recommended 50 ohm double shielded coax antenna cable vendor and the type to be
used for specific lengths of cable. Adherence to this table will ensure that the coax installation will not exceed
the maximum allowable 1.5 dB attenuation at the transmitter operating frequency of 1090 MHz.

Supplier Information
One of two rack connectors is provided (item 6 or 12 in the installation drawing, figure B2). RF Adapter item 12
(P/N 330-00326-00) requires the cable to be terminated to an appropriate type BNC plug (provided by installer),
which is then attached to item 12. Any 50 ohm, double shielded cable may be used, provided it introduces less
than 1.5 dB attenuation at 1 GHz including the connector.
Connector item 6 (P/N 330-00198-00) requires the cable to be terminated directly to it and can accommodate
only M17/128 (RG-400) cable. The completed cable including connectors must introduce no more than 1.5 dB
attenuation at 1 GHz. Instructions for installing the item 6 are shown below (steps A-G).
