Version 16.10 AF-6600 AF-5000 Series Install Manual 105
The following table is a guide to the maximum usable lengths of some common cable types. Actual cable loss varies
between manufacturers, there are many variants, and the table is therefore based on typical data. Use it as a guide
only and refer to the manufacturer’s data sheet for your specific chosen cable for accurate values.
Antenna TNC Connector
This section describes the technique for attaching the antenna cable to a TNC connector. A TNC connector is not
supplied with the SV- 261. The SV-261 has a female TNC connection. Therefore, you will need to source a male TNC
connector that is compatible with the antenna cable type that meets your aircraft’s needs.
A dual crimp style TNC connector can be completed using a wide range of commercial crimp tools (for example the
Tyco 5-1814800-3). The die apertures for the inner pin and the outer shield should be approximately 1.72 mm and
5.41 mm respectively.
• Strip back the coax cable to the dimensions in the table, as shown in the diagram below. Slide 25 mm (1 inch)
of heat shrink tubing over the cable.
• Slide the outer crimp sleeve over the cable – it must go on before securing the center contact.
