This is the example.. the pencil will be the ac cord.. wrap the wire as shown, then connect the wire to the screw labeled 300.. Then wrap the wire in tape to keep it from sliding.

related, I find it really neat how fractal geometry is effective with antennas

and they are used in all cell phones and such to get good reception and frequency response in a small package. This sort of thing really peaks me, that shape has such an important role in nature.
case in point, airplanes are kept in the air, pretty much solely because of what shape they are.

That's true Wirez.. Very true..
Example my antenna for HF is center fed by coax.. It works well on 3 bands.. the total lengeh is 130 feet long.. 65 x 2 legs of wire.. If I slide the center feed point to where one side is 90 feet and the other side is 40 feet I will gain seven bands total,, all by geometry.. Wonderful isn't it! and its quieter too.
