EARCHI 9:1 unun enclosure

This is an enclosure that I designed for the EARCHI 9:1 unun. It also works well with other baluns or ununs using the T130-2 powdered iron toroid or other toroids with similar diameter. There are two options. The first option uses binding posts on one end. The other option uses #8 bolts with wingnuts.

Details on how to build the unun are here: http://www.earchi.org/92011endfedfiles/Endfed6_40.pdf
