Got a chance to try diversity reception on the flex 5000. Ever since I put the new antenna up, I have a lot of noise as its closer to the cable and phone lines in front of the house, 20 feet closer and within 10 feet maybe, as that is the only good tree I have left out front. I put the 80 meter dipole into one antenna port, the roof mounted zero 5 vertical antenna into port 2 and turn diversity on. There is a target you can move within a circle to null noise. It works! I can eliminate the noise to almost or even nothing. The downside is if you move frequency you have to re do the setting. Still, its quite amazing.
