For those who have access to the February issue of QST there is an informative article about the relation of trees to antennas in close proximity to each orther. Test were performed across many ham radio bands in both the vertical and horizontal plane using NEC software. It turns out that what Rich Fry has been telling us all along is correct. Trees have little or no effect on antennas on the 160 meter band. (1.8 to 2 MHZ) So it is safe to apply this data to the AM Broadcast Band.
