Hi All I have 3 phased verticals for 40 and an inverted "L" for 160. At the base of each of these, I have a pretty extensive radial system. I run a wire from the radials at the base of each antenna to the radial system on each of the other 3 antennas. What I was wondering was: 1. It helps 2. It hinders 3. Makes no difference. 73 Tom W7WHY
