4" Balun Enclosure by AB3ZI

Enclosure designed to accept a 2.4" OD wound toroid. Provision is made to attach a SO-239 chassis connector for coax. Lid and enclosure mating surfaces include a chamfer intended to accept some sort of sealing compound, like silicone or duct seal. Screw holes measure .094" in diameter. The enclosure is intended to be mounted to something more rigid, like plexiglass, to accept the tension of a wire antenna.
