I have a homemade antenna on my roof that's roughly 10 years old and parts are starting to degrade. One thing that didn't really exist was mainstream access to 3D printers. So right now I'm printing spare parts to rebuild my antenna.
That's what I've printed so far, a few things are a bit off and I'm optimizing things.
Currently going with this setup as my likely final product.
With this being an alternate design if I change out the bow-tie antenna for a Gray-Hoverman.
Current work in progress.
