Topband: EZnec - 4nec2 - MODELING THE 1/4 SLOPERS.

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.
