    Has anyone here done something like this or similar?

    I've got two 5' Wilson silver loads that I could try this with but this is different than the other dipoles I've seen as far as how the coax is connected to the antenna.

    Nothing unusual there. same old way ,! whip to the coax centre conductor and the other whip to the braid .If your short of room go for it. If you have the room make a full size dipole ,much better performance.

    Ahh is see now. The antenna on top doesn't have an isolator on the bottom of the antenna stud mount so the outside of the antenna mount is "connected" to the braid which is connected to the bottom antenna. Did that make sense? For some reason I thought it did.

    I've got a full size dipole but just wanted to build something and try it.

    Problem with vertical dipoles is with running the feedline away from the feedpoint. It should be at right angles to the dipole itself for at least a half wavelength. From the pictures in your post, it looks like the guy only ran it a couple feet and then just let it hang, parallel with the dipole.

    Picture a conventional dipole. The coax is hanging straight down from the center insulator, due to gravity. That can't be done with a vertical dipole. I suspect the guy who wrote the article could have avoided a lot of his tuning problems by considering this.
