Next, leave a few inches (~6) beyond the last turn on the coil and cut the wire from the spool.  
This end should be long enough to be passed through the holes in the form.  Push this end trough
the holes at the end of the coil as was done when starting the coil winding so that it comes out 
the other side.  Secure the end with another crimp terminal and cut off any extra wire.  Secure the
end by soldering or crimping the wire to the terminal and connect with a screw and washer.

Coil Tap Assembly

The flying tap lead is created using the test clip lead with crimp 
terminal placed on the end and covered with heat shrink tubing.

First, strip approximately 1/4” of the insulation from the end of 
the clip lead wire.

NOTE: Be sure to slip the shrink tubing over the wire before 
attaching the ring terminal.

Next, attach the ring terminal on to the stripped end of the wire by
crimping and or soldering. 

Once the wire is crimped, slide the head shrink down and over the
crimped area of the ring terminal and apply heat to shrink the 
tubing to secure the wire and protect from flexing.

 Once the lead is complete it should be secured under one of the screws at the end of the coil 
form as shown below.

This completes the
assembly of the PAC-
12 Multi-band coil.
This is how it should
look when completed:
