Had my most amazing Ka encounter YET today. About 1/4 mile to a light, I started getting blips of Ka band. It ramped up more and more as I neared the intersection. I was waiting at a red for a left turn, and I saw a smoothtop crown vic roll across the intersection... Aha I thought, 1/4 mile perpendicular Ka band, impressive. Well, the V1 wasn't done amazing me yet. The cop pulls over the guy in front of him and I passed the two, and now the V1's showing full Ka from the rear. It continued detecting the signal for over two miles over decent sized hills, and I only lost him when I finally needed to turn again.
This kind of Ka sensitivity blows my mind... WOW.
