EFHW Case

This is a small EFHW design that uses a Fair-Rite 2633251002 Core (Mouser), wound in a 49:1 configuration. I used 16 AWG magnet wire and it fits tightly. The antenna and ground connectors are 4mm Banana Plug Socket Speaker Terminal Connectors, the SO-239 is a 4 hole Chassis Mount Connector - all parts found on Amazon. I drilled the holes on the side of the tube for the chassis screws.
