"How would you like to INCREASE the warning time you get on speed cameras while DECREASING the annoying false alerts you get from automatic door openers at shopping centres and petrol stations?"
EXCLUSIVE TO DELONIX RADAR
The biggest complaint we receive from owners of radar detectors is the amount of false alarms you get (caused by microwave automatic door openers and security sensors) when driving in the city.
You know the scenario - every time you drive past a petrol station (gas station for our US friends) your radar detector beeps like crazy on K-band, and once again you reach forward and hit the mute button whilst your passenger looks at you with that "what the hell is all that noise"? look.
You get so good at picking where the false alerts signal, that you find yourself subconciously reaching for the mute button just before it beeps on your daily commute.
Any of you "Beltronics" owners familular with those "Cave Man" alerts?!
In dense shopping areas, you almost want to throw the radar detector out the window with all the beeping that goes on. You see, those false (K-band) alerts are caused because most automatic door opening systems (as well as other things like security sensors and the like) operate on the same frequency as (K-band) police radar. And a radar detector cannot distinguish between a "real" police radar and these "false" signals since they operate on the same frequency (around 24.15GHz)
The second biggest complaint I have received are from members that encounter low powered speed cameras such as Multanova, Ramet AD9, Ramer 7M, Gatso. These radar speed cameras operate on such a low power, that they are very difficult to detect - only the very best radar detectors give any kind of "advanced" warning.
In fact, when any of these type of speed cameras are set up "rear facing" (in other words taking the photo of your car AFTER you've passed the camera) most radar detectors only "beep" as you draw level with the camera - effectively giving you about 1 second warning.
The reasons why radar detectors don't give much of an advanced warning on these cameras are
1) The speed cameras use very low powered radar as already mentioned but
2) Because unlike the "dash mounted" radar on police cars, these speed camera radars use what's called a "polarized" radar signal.
You see most police radars have "circular polarization" so it makes no difference whether your radar is mounted vertically or horizontally, you'll get the same warning. When these radars transmit their "radar beams", the radar shoots out of the gun in a cone like fashion. So as the radar beam leaves the gun, it spreads out in a circular pattern, getting wider and wider the further away it travels.
But the above mentioned speed cameras are different. These cameras are horizontally polarized, while your radar detector antenna is vertically polarized. So by turning your radar detector on it's side (by 90 degrees) you are in effect now matching the polarization of the incoming radar beam with your radar detector...giving you longer warning times.
This phenomenon is especially apparent with Beltronics radar detectors. Speak to any RX65 owner and the story is the same (and matches my own experience) - one day you get 300m warning on a camera, and then the next time you get 40m warning! It's these inconsistencies that are smoothed out when you match the polarization of the speed cameras.
Still unsure?! Read the discussions on the radardetector.net forum
or the more scientific explanations here: http://www.microwaves101.com/
thus you'll get the most warning by turning the detector 90 degrees on it's side to match the polarization of the speed camera.
