PVC Bushing for Antenna Construction

I don't throw much of anything away and I have a slew of 19mm tent poles. So I decided to make a Yagi-Uda antenna. The problem was the poles were too sloppy in the PVC fittings. I came up with this for a solution. It has to be chased a little with a sanding drum, but better too small than to large. In my use it was only a slight buzz from the dremel and I was smacking it together with a rubber mallet. No screws are really nessissary. Well you will need screws for the dipole.
