This is only the proof-of-concept prototype.
I have been cooking a design for a backpackable 4-element Yagi antenna for some time now.
The basic idea is to make a telescopic boom out of two PVC pipes and have removable elements that store inside it.
It took me some time to figure the method of attaching the aluminum welding rod elements (used Kosh electrical connectors) and how to integrate the feed point inside the boom. This will be the next build step.
