I second your results on Trango. I had 3 Atlas 5800 units on top of a very lightning prone 550' tower in West Palm Beach since 2003. I know they took hits because the switches on the bottom lost ports on a monthly basis even with LP protection. I finally ran fiber to the AP's whcih took care of the switch issues. Trango - just set'em & forget'em!
