Directional "antenna" maybe	by Menetlaus	2008-08-22 09:46:59
It'll still be inverse square.	by bwkaz	2008-08-22 09:51:53
How's that?	by Menetlaus	2008-08-22 11:54:12
It's not inverse-square, or plain inverse.	by bwkaz	2008-08-22 12:23:56
It is inverse square if you are far enough away	by hej	2008-08-22 14:25:31
The intensity of radiation from a point or line source decreases with the inverse square of the distance to the source. In a real situation the "inverse square law" works iff you are far enough from the antenna to treat the antenna as a single point rather than a 3-D object. If you are right by the antenna it looks like a wall instead, in which case the intensity is independent of the distance, and at some medium distance it diminishes slower than by the inverse square.
