I have made a vertical for 40m. it is an prototype to see how it working and what I have to change when I need 4 of these for my for square. I mounted it next to the shack at the fence. At this place it picks up a lot of noise from the house and the shack. Will move it to the land soon. To connect the coax and the radials I made a connection box. I think that when engendering is finished I will fill the box with resin.
