I received my third Atlas sensor...this one with the lightning fix.
After a week, I have not had any false strikes. I also installed lithium batteries.
I did not want to jinx it and take any parts off to see what they did but I did notice the markings and the wires:
I still do not know if the UV is working correctly though. My first unit worked fine, the second only went to two. This one is only going to three while another unit I have and the local airport will report 5.
While it has been a royal pain dealing with this (three units in one month), their customer service did improve greatly compared my experience with the Access.
