SV-XPNDR-261/262 Installation and Configuration
SkyView System Installation Guide - Revision AA 11-15
a TNC Female connector. Therefore, you will need to source a TNC Male connector that is
compatible with the antenna cable type that meets your aircraft’s needs. Alternatively,
especially if the transponder antenna you have purchased incorporates coaxial cable and a
“BNC” connector, you can purchase a “Male TNC to Female BNC” adapter (see below).
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.
Table 78 – Coaxial Cable Strip Dimensions
Crimp the center contact to the cable.
Insert the cable into the connector – the center contact should click into place in the body,
the inner shield should be inside the body of the connector and the outer shield should 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.
TNC to BNC Adapter
If you have purchased a transponder antenna that has coaxial cable
and a BNC connector already installed, you can use a “Male TNC to
Female BNC” adapter to adapt the SV-XPNDR-261/262’s TNC
connector to a BNC Female connector. As this adapter will be used
for transmitting radio frequency energy above 1 GHz, we
recommend that you purchase an adapter by a reputable
manufacturer of radio frequency connectors and adapter such as
Amphenol. The part pictured at right is an Amphenol P/N 242149,
and is available from Digi-Key as P/N ACX1378-ND.
