The main part is a 3D printed head that fits on what seems to be a standard tent pole tip and holds the two arial elements of the inverted V which are soldered to a common BNC connector. I used a single guy wire made from standard parachute cord and the two arials to get the mast standing. The arials are terminated with little 3D printed ties and more p-cord
The most expensive part of this was the coaxial cable, which I ordered from DX engineering: https://www.dxengineering.com/parts/dxe-8xdb050
The arial elements are made of reallt common stranded THHN wire I picked up from my local hardware store. The BNC connector fell off a truck somewhere.
All 3D printed using standard PLA on ubiquitous Creality printers. All printed parts were designed in FreeCad and I will make them available so you can adapt them to the materials you have handy.
I have tested this on my Xiegu X6200 radio, and its little SWR meter reports less than 1.5 SWR.
I'll connect it to the NanoVNA and see if I can get a smith chart to show on here, but it works surprisingly well.
