Therefore, you will need to source a male TNC connector that is compatible withthe antenna cable type that meets your aircraft’s needs.A dual crimp style TNC connector can be completed using a wide range of commercial crimptools (for example the Tyco 5-1814800-3). The die apertures for the inner pin and the outershield 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 centercontact.DimensionCrimp the center contact to the cable.Cut size(mm)Cut size(inches)A 17.5 0.69B 7.2 0.28C 4.8 0.19Insert the cable into the connector – the center contact should click into place in thebody, the inner shield should be inside the body of the connector and the outer shieldshould be outside the body.Crimp the outer sleeve over the shield.Slide heat shrink tubing forward (flush to connector) and heat to shrink the tubing.Transponder-Related SkyView Display SettingsSerial Port SetupBefore the TRANSPONDER SETUP menu can be accessed, the SV-XPNDR-26X needs to be set upas a serial device on each SkyView display on the system.
