Well i finally found a decent location for the overpass testing i've wanted to do.
it's about 15' up, plus another 5' or so for gun height.
i shot from 1 lane over and about 3-4 lanes over for front shots, and about 1 lane over for rear shots.
This was mainly a Blinder test with some ZR3's added to the mix.
i had several questions i've been wanting answers to.
1. How does performance compare to side and straight shots?
2. Does height affect jammer performance to any big degree?
3. Does my setup work to protect me from overpass shots, front and rear?
4. How well do jammers do through glass, and can glass/tint affect performance?
5. How about roof shots?
well i've been able to come up with the answers now.
First, as i suspected, my jammers had a bit more of a struggle with overhead shots. my reason for this suspicion is because i noticed that when i look at the jammer heads firing with a camera, as i move the camera up or down, this affects the intensity of the beam. level with the camera gives the brightest intensity.
For those that have seen my videos, i can obtain JTG and JFG results, consistently from straight and side shots.
so how did i do with overpass shots?
from the front, i was able to get PT's from about 77' up to one with about 220'.
i had a JTG, but the gun shifted at the last minute.
in the real world fortunately this won't be an issue in my case, as i had no problem jamming from beyond that, and at that range you would see them, but nonetheless, PT is PT.
the rear was a different story. Due to my low mount, the Blinders really struggled. i was able to get several PT's at different distances.
The ZR3's in my rear window had trouble and did not help much with the window up. however when i rolled the rear window down, i got a JFG!
So the shifters helped on a high shot, but not as well if they are obstructed by glass and tint.
the overpass shots definately take advantage of weak spots in a setup.
i was able to pull some roof shots on cars, including mine without jammer, but not with, since i have a shifter sitting top and bottom of my windshield, facing up at an angle.
from ground shots i can't get a roof shot reading either, not even with jammers off.
with the ease of frontal shots, roof shots are much harder and would be a "last resort" i believe.
while i continue to sift through video footage, here's a little teaser for you, through the scope of course.
