NOTE
Any QMA terminations used other than those specified in Table 2-2 will constitute the
installation as being non-compliant with the manufacturer’s installation standards.
2.4.1.3 Fabrication of Coaxial Cable Assemblies
The installing agency may fabricate cable assemblies by terminating either M17/128-RG400 or
M17/60-RG142 coaxial cable with available QMA connector kits. Table 2-2 lists recommend cable types
to be used with specified QMA connectors for the GTS 8XX.

The recommended coaxial cable lengths in Table 2-3 are for reference only. Along with standard MIL-C-
17/128-RG400 or MIL-C-17/60-RG142, Table 2-3 lists recommended antenna cable vendors along with
the cable type that each specific vendor offers. The recommended coaxial cable lengths are defined as the
end to end length of a non-terminated coaxial cable. The attenuation values listed in Table 2-3 include
the maximum attenuation of both the maximum length of coaxial cable and two RF coaxial connectors at
a frequency of 1090 MHz. It is the installing agencies responsibility to ensure that the coaxial cable
assemblies built meet the manufacturer’s attenuation specifications in order to comply with the
manufacturer’s installation standards.
NOTE
Any in-line or bulkhead penetrations must be evaluated separately. It is the installing
agency’s responsibility to show airworthiness of the installed fabricated or purchased
coaxial cable assemblies.
