Has anyone modeled the 1/4 slopers? Perhaps the Alpha Delta DXA?
The pattern and performance of a 1/4 wave sloper is extremely dependent on the tower and what is on the tower, the guy lines (if uninsulated), and even how the tower is grounded.
There are very common cases where it won't work at all, cases where it works fairly well, and everything between the two extremes.
