K6MM’s No Excuses 160m Vertical Antenna

Photograph 1 depicts our first attempt at helically winding 97 feet 1 inch of AWG#14 wire on 2 inch PVC SCH40 before re-thinking our strategy. I opted for removing the long screw driver on the wire spool and approached our problem like taping a piece of pipe. I maintained upward and downward tension using the spool.

Photograph 2 facilitated third person in this operation because handling a 10-foot piece of PVC is difficult to balance while winding.

Photograph 3 demonstrates our solution in addition eight inch lengths of halved duct tape at every 12th or so wind. We found taping at this interval suitable enough to maintain adequate tension. I attempted, to the best of my ability, half inch spacing between winds however I’m not satisfied with the quality of my work. Therefore, the next step in our project, includes adjusting each wind accordingly.

Photograph 4 illustrates the end result of three hours of labor. My plan is to replace the spade located at the binding post while spacing each wind according to K6MM’s instructions. We divided each each section by the total length that is 256 feet 5 inches of wire equaling an average of 85 feet per section. Additionally, I’m purchasing alligator clips for each section because I’m intending to deploy the antenna in the portable mode.
