I would like to know what the effect of 2 or 3 RD's is on the spectre RDD signal strength wise. If you have 3 RD's on at the same time in your vehicle, will it give you a full strength signal with the spectre from a farther distance or will it have the same signal strentgth with just one RD from the same distance. I would like to see a test done to it. Results will be very interesting if 3 RD's can turn the spectre's signal to full strength. This may let LEO think that the vehicle with an RD is so close but in reality is still far away forcing him to possibly turn his radar gun and thereby detecting it in advance. This is just a thought. Who knows, it might work.
