Just spent an informative hour testing our laser jammer with the help of a guy that imports all the top detectors, etc. He's has one of the latest Stalker laser guns that our cops are using, supposedly has anti-jamming capability. We found that our prototype still needs developement, coverage is poor, but at least it works.
Our old generation laser jammers still work OK on the Stalker, which surprised him. Wouldn't be too safe on large cars, but fine for bikes. He was a mine of info though, apparently BEL own Escort/Passport now. It's the same guts in a different box. BEL have a new range coming out, with ultra fast response time. Sensitivity is a smidgeon less than Valentine, 112 db as against 114db. BEL's and Escort units have greater range if mounted on their sides, that's the proper orientation of the wave guide.
The Valentine rear antenna is more sensitive than the front on Ka band, gives .5 km more range if mounted backwards. The reason is that US detectors are biased towards X and K band, but Mike Valentine used a Ka biased wave guide in the rear.
It also pays to take comparison tests with a grain of salt, radartest.com is owned by BEL and some of the other websites are a bit suspect too.
It seems that the 5km/h speed tolerance is going to apply to urban areas not open roads. It wouldn't be due to the fact that most fixed cameras are in urban areas, would it?
