End Feed Half Wave Transformer case for T140-43 and SO239

This is an end feed half wave antenna case for a T140-43 toroid with an SO239 connector. You will need some enameled copper wire, a T140-43 toroid, 100pf - 110pf silver mica 1-2kv capacitor and banana plug to complete the construction, plus some connectors and wire.

I would suggest the maximum watts you put through this is 100w on SSB and no more than 50w CW and Data modes.

You only need to put a resonant half band of wire onto the banana plug for this to work.

I would suggest ony usin
