Pete, I added 4 radials and a 4' ground rod like you did. I am not sure if adding more will help, but I am pretty sure it could not hurt, so it might be an easy test. Another thing I did which seemed to help was to cut the trace as described in the documentation to isolate the feedline shield from the ground of the antenna. I also put a feedline choke on the coax near the antenna to try and make sure the feedline was not picking up signals and disrupting the pattern. My choke was 6 turns through 5 stacked #31 cores. I am quite happy with the performance of it. Good luck!
