The elevation pattern for this phased array of vertical elements shows a forward elevation angle of maximum radiation of 16 degrees. The corresponding rear elevation angle of maximum radiation is two degrees lower, at 14 degrees above the horizon. Although the difference may not make a very significant operational difference with this array. In this case, the elevation pattern supplements simple azimuth patterns. Of course, we can always turn to the far field tables for both elevation and azimuth patterns to complete our data needs.
Many antenna modelers approach the software with limiting assumptions.
In this set of exercises, I hope we have gone some distance in showing this basic idea to be somewhat more complex than some of us suspected.
