I tried a different coil diameter, spacings, #'s of coils, copper tubing of 1/4" diameter, and length of the coil itself. I also tried different lengths for the shafts and stinger. This is where I've landed so far and intend to keep steering it in the direction I get best results.


Right now it has tremendous ears, and permits seeming flawless communications both on the local and DX level. That said, I know this is the efforts of a homebrewer who does this for the fun of discovery. My only goal is to see if I can do it, and to get the opinions of those who know more than I do, as well as those as curious as I am. I learn and have fun all at the same time.
