Wanted a clean connection point for my new J-Pole so I put this together. Works with a SO239 chassis connector and keeps the 1/2in copper pipe 2 inches apart as a spacer as well. Inside, I actually used hose clamps to hold ring terminals against the copper pipe so I could easily slide them around as needed to tune it. I got it to 1.1 SWR across the 2m band with this one by using that method. The case looks great though and allows for easy cable hookup. I plan on sealing the edges with epoxy as well to help with weatherproofing.
