Thanks to Sparkie (2E0VOV) for this simple, concise, and easy to understand project.  For those of us using random long wire antennas, a 9:1 unun is almost a necessity if we hope to avoid serious SWR mismatches to our equipment.

According to Sparkie, materials and tools for this useful antenna accessory are readily available:

"Welcome to another project.. The core used is a T200-2 with 9 trifilar turns of enamel wire. The box is 120mm x 80mm. All bolts are stainless!. An easy project to home brew and cheap to build. Some of my equipment.. FT817 radio 17m whip antenna 20m whip antenna 10m Antenna pole Antenna Analyser 73 Sparkie 2e0vov"
