EFHW Antenna with BNC and FT-83-42 Toroid

EFHW antenna base. 4mm screw holes. 6mm support holes

Fits this toroid: https://www.amazon.com/dp/B084LVGZ9Q

Has optional ground connection hole and counterpoise hole.

My personal design uses a counterpoise and I DO NOT connect it to ground. I also do not use a capacitor, but you of course can build it as you wish.
