BNC Aerial RG58C/U 50 ohm Coaxial Cable
All wiring is connected by soldering to the DB15 connector. Inspect the solder cup side of the DB15
carefully to determine the pin numbering.
Strip the insulation back 2mm (1/16”), and “tin” the exposed conductor with solder. Slide a 5mm length
of 1.6mm (1/16”) heatshrink tubing over the end of the wire. After checking the wiring diagram for the
correct pin number, push the “tinned” end into the “tinned” solder cup, and solder into place. Check the
soldered joint has been made, by gently pulling on the wire. Slide the heatshrink tubing down over the
soldered pin, to completely cover the conductor.
