It's pretty easy to understand. Any two radials, 180 degrees apart and high enough, should theoretically cancel each other's radiation in the far field. Not true. There is always an angle and direction where the fields do not fully cancel. The problem is the spatial distance is different unless exactly broadside to the pair. Even 4 radials has this problem, but the more radials the less of an issue it is. 73 Tom |
