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..
