- Larry, My 80 meter vertical feedpoint is about 2.5 feet from the actual ground (dirt). The radials leave the ground ring downwards to the dirt at a 45 degree angle. They are staked at the point they

- Just remember, if you run radials at a 45 degree angle from the base of the vertical, it will effectively shorten the electrical length of the vertical by the same amount of elevation. That is, if th
