According to the instructions, K40 Radar Receiver has to be mounted in the open with out anything blocking it, just like Laser Jammers.
So if you place V1 or Escort right next to K40 Radar Receiver, the detection will be equal.
Proper testing has to be done. Other wise its pointless to argue and above videos are irrelevant. Thus everything that was stated here about K40 is nothing more then personal Opinions.
