EFHW - End Feed Half Wave Transformer case for T50-43 and Female BNC

This is a case for a QRP End Feed Half Wave antenna transformer based on a T50-43 Toroid.

You will need a T50-43 Toroid, Banana Plug, 100-110pf Silva Mica capacitor rated at 1kv, enameled copper wire for the windings, BNC panel mount socket, antenna wire and some connectors to complete the antenna.

Being a broad band transformer design you can run this multiband as long as your antenna wire is long enough to support higher band resonance.
