EFHW unun

I thought I might post a couple of pictures of our recent club Unun project.



Hopefully the photos will upload. I was a train driver. This project had me well outside my comfort zone. first I drilled the holes in the box. The instructions said to be careful with the positioning of the posts and the SO239. Next I wound both the unun and the balun. Before I placed the components in the box, I laid them out on my work bench. Then the dig for my multimeter with the buzzer. I found stripping the copper wire an issue until I found my small file set. After filling and measuring and checking continuity al components were loosely fitted into the box. Then came the job I dreaded the most. Soldering. I hate soldering almost as much as ironing. However the soldering proved really easy. The results. I chose Kurth Kiln campgrounds to try out the unun and the EFHW. Works good. The only problem I encountered was the 3D printed thingy broke. My fault. I didn’t glue it into place. And it got dropped on the ground. Not good. Would I do another club project? Yes. There has been talk of doing a loading coil for 80. Let’s do it. I would be happy carrying around the unun a loading coil and forty meters of wire. Stanley J. Mitchell VK3BOT
