Something does not look right. The 50 ft and 500 ft patterns lead one to believe there is absolutely no radiation below zero degrees elevation and we know that is not the case. Null fill and beam tilt is generally rarely used and only when the antenna is at a great EHAAT and needed to fill in relatively close in.Beam tilt rarely exceeds a couple degrees. The general shape of the 50 and 500 ft patterns even with the multiple nulls generally follows the same overall shape as the free space pattern shown above zero degrees elevation and hence my statement that they are essentially the same.

Where did you get those patterns? I tried to link to the images to find out a bit more about them but couldn't.
