Radioddity HF-009 Antenna Holder

This jig allows one to stand up the Radioddity HF-009 vertical antenna with a simple 1" hole diameter weight plate.  It also has a hexagonal hole in the bottom that one can put a ¼"-20 rod connector nut into.  This allows one to mount this on a ¼"-20 post on a tripod mount.  

Both the round hole on the top and the hex hole on the bottom are a snug fit.  The ¼"-20 connector you get from the hardware store may have a slightly different dimension depending on who made it.  The quality of the print from your printer may also impact fit.
