I also had the antenna upgrade and I see the "green" marks only stay for about 6 or 7 feet from the camera, then they turn yellow and, really quickly, getting away from the camera, to red.
I must say I've tested it in "red signal" up to 36 feet in a really closed space, and it worked fine. So I guess it's an improvement, but I hoped the signal to be more time in the "green" range...
