Printing time for this project is quite extensive but you will not regret either the filament used or the time spent printing for one moment. Parts are easy to print without issues.
The end project is a professional looking antenna that looks and works well. Well worth your time spent.
I have seen many antenna designs here but none met my needs. I required a reasonably strong and light weight. The complete antenna weighs out at around 650 gram (~23 ounce) with good strength. My drawing skills are limited, hence mostly parametric parts readily available on Thingiverse were used.
This is an attempt to create an easily constructable 3D printed version of the excellent 2m/70cm 2+2/3 El antenna design by DK7ZB.

Should you require more bandwidth/better SWR on 70cm, you can build the antenna without the third 70cm element with a bit less gain. I suggest you read Martin, DK7ZBs page on the link above before d
