PVC Bushing for Antenna Construction

thingiverse

I'm a bit of a pack rat, never throwing anything away if I can help it, and right now my collection of 19mm tent poles is multiplying like rabbits. So when I decided to build a Yagi-Uda antenna, I knew I had most of what I needed right at home. The only problem was that the poles were a bit too loose in their PVC fittings - they'd spin around without any real stability. That's when I came up with this solution: it takes some elbow grease and a sanding drum to get it just right, but better a little too small than a little too large. In my case, it only took a few seconds with the dremel before I was hammering away at it with a rubber mallet. No screws are actually necessary - except for the dipole, of course.
