5. Strip back the insulation on either side 3/8 of an inch (1cm).
6. Bend each exposed wire at a right angle in respect to the flat side of the
antenna wire.
7. Mount the antenna wire to the component side of the PC board (the side
Twin lead wire viewed sideways
with no solder traces). Bend the twin lead antenna wires down through the
PC board holes and over on the other side for a good mechanical
connection. Solder both leads tight to the board.
8. Cut the piece of bus wire into three 1" (2.5cm) pieces.
9. Use two of the pieces to hold the antenna wire tight to the PC board as
shown.
10. Now we will prepare our coax wire for threading through the board and
soldering.
11. Strip back the outside shield 1/2" (1.5 cm) using a sharp blade. Be
careful not to cut all the way through the shield wires when doing this.
12. Bunch and twist the shield wires together and solder them into a
