Marker Beacon Antenna Cable Installation
This section provides guidance for terminating the coaxial cable into the D-Sub connector. See the
system interconnect section for pin assignments.
NOTE
Use coaxial cable meeting the applicable aviation regulation for the marker beacon
antenna. Route the cable to the D-Sub as described in Section 2.3.1.3.
When terminating the coaxial cable into the D-Sub observe the following guidance (refer to Figure 2-1):
•
Keep the distance from the end of the exposed shield to D-Sub as short as possible.
•
Ensure the distance from the beginning of the exposed shield to D-Sub is no more than
1.5 inches long.
•
Terminate the center conductor by directly connecting it to the D-sub through a crimp pin
without a pigtail.
Figure 2-1 below represents a suggested method for terminating the marker beacon coaxial cable using
M17/128-RG400 terminated into a
78 Pin high density D-Sub connector. Refer to Table 2-1 for Crimp
Tool, Pin, and Crimp Tool Insert part numbers.
