CONSTRUCTION OF THE TM100
1. Cutting the ladder-line twin lead antenna wire. To properly 'size' the
antenna, we will want to center our measurements from the center point of
the twin lead wire. Then measure from this point out exactly 27 inches in
each direction as shown and then cut. You will need some fairly
substantial clippers since the wire is copper coated steel (known as
copperweld).
If the wire doesn't have a "window' or cut-out section of plastic
insulation in the center, simply use a sharp knife to cut away the
plastic to create a clear area similar to the other sections. The size of
the window area is not important, just as long as it is at least as big as
the other areas.
2. Strip back all four ends of the antenna wire 3/4 of an inch (2 cm).
3. Bend over each wire of the end connections so they meet. You may
want to bend them with a pair of pliers since the stiff wire will twist in the
insulating material. Solder these ends together securely.
