9500i vs. V1 Test

[KnightHawk]

Planning to do a test with K and Ka band off axis at 90 degree angle with constant on.

Here's the situation. Will be positioning the vehicle with radar in front of my house facing some good amount of trees. Radar will be facing east and test vehicle with detectors will be running north/south. There will be no other vehicles during the test route north/south because this is a dead end road.

I'm concerned about reflected or bounced signals from the trees and there could be some wind too to consider which will eventually move the branches and leaves. My plan is to have the detectors alert me continueously for 5-10 sec. - don't know if this is the time that's needed to exactly validate the test. Reason for this is, if i base it on the last alert, it can be from a reflected signal say from a movement of a tree caused by the wind and would get inconsistent results. Also, i noticed in the past that when the radar source is turned off, the radar detector still alerts you even though the source was turned off already - there's sort of a delay alert. So if i get a steady alert for an x amount of time, that proves to me that it's picking up a good signal and the radar detector that can hold the alert for an amount of time at the farthest distance will be cosidered the winner. Would that be a fair procedure? Will be doing the test front and rear. Any suggestions and comments on how to do the test will be welcomed.

I don't understand the need of a 90 degree off-axis test as I don't believe any cop would even attempt a stop at that angle.

Factor in all the reflective surfaces in the vehicle and it seems pointless, not to mention a moving reflective surface?

I'm missing something here. 'Splain to me why this is a good test? :?:

I could see a turn with a building or canyon for a bounced signal, but moving leaves?

Purpose of this test at 90 degree angle is to shorten the distance. If i do it at right axis, it's going to be long distance and would be over a mile which i don't have much space to work with. I did not want to have a moving reflected source because you get more insonsistentcies. I believe a stationary environment would be easier and would give me consistent results although it's not a perfect one, i believe it will give me some answers. We do have a stationary Ka speed sign near by but traffic is a major factor. The 9500i has been giving me the alert first with the Ka band speed sign but needed a controlled environtment although not 100% but could give me a higher percentage of consistency.

Hate to say it but I don't thinks it's a good way to test. Myself and many others have noted that the Belscorts do not look at as wide an angle as the V1. Therefore driving straight at the target is the best comparison.

Even those testing the V1 vs 9500 should not count on driving down a road where the door openers are to the left & right sides. Locate a K-band door opener that is straight ahead, drive out of range and then back towards it.

If you can't point up a street, then how about positioning a vehicle in a driveway and reflecting a signal up the street off of the vehicle. If you're trying to weaken the signal because your street is not long enough, then how about setting the radar unit on a seat in a vehicle?

No problem microbb. That's why i post this to gather ideas and suggestions. I can surely try your your suggestion. Although the belscorts do seem to have a tunnel vision, the 9500i alert me first from a cruiser that was coming from a 90 degree angle before the V1 did and gave me 3 beeps before the V1 alerted the first beep. This is just an experiment and just wanted to see how the 2 react. This is by no means a basis for true testing. It's just for curiousity sake before the 9500i goes back to it's owner.

You might also try same direction but pointing away to simulate a photo radar trap which would nail your rear licence plate as you go by. This is usually very hard to detect in time.
