Best Place to Mount a Radar Detector

We know that correct placement of a radar detector is essential for proper operation. But where is the best position to mount it so that it can deliver maximum performance? Should it be mounted down and low on the windscreen or high up close to the rear-view mirror?

Though there is divided opinion, understanding of the device and some technical knowledge may help us to ensure that our detector is installed correctly. Not mounting the detector in the right position may cause the device not to function at all in certain situations.

Understanding the Radar Detector

A good starting point for the end user would be to consult the manual of the device manufacturer. It helps one to gain technical knowledge on where the detector’s receiver antennae(s)/laser sensor(s) are located. It also provides guidance on how the device needs to be mounted so it can be exposed to radar and laser signals in order to provide an alert.

It is most likely that a police officer when using LIDAR will aim the laser to the front license plate, the front grill or the headlight there is a good chance that devices mounted high near the rear-view mirror has lesser probability to detect this signal.

Guidelines for Mounting a Radar Detector

Some of the guidelines that can be followed when mounting a device are

1) Choose a location where the units receiver antennae(s)/laser sensor(s) are not obstructed by metal surfaces
2) Install it in a level position
3) The unit should not block the drivers vision
4) Do not mount the detector where the driver or passenger might hit it in a sudden stop or accident
5) Avoid locations that is exposed to high temperatures

High or Low Mount

Few practical tests were conducted by mounting the detector low and high on windscreen to determine its performance. The Escort 9500i and the Valentine V1 were used for this test. The end goal of this test was to determine the distance at which the unit was able to provide an alert. Then compare the distances to determine the one that was greater.

As you can see from the graph below both the detectors where able to detect the radar signal at a greater distance range when mounted low.

Similar tests were also performed for laser signals and it was observed that radar detectors alerted to the laser guns more when mounted low on the windscreen

Based on the test results it can be noted that the performance of a radar detector is high when mounted low with the antennae and sensor having a clear view of the road.

Conclusion

Consulting the product manual to determine the mounting position should be the first preference for any user of a radar detector. However, if you are unsure then based on the facts and technical information available it is best to mount it low and centered on the windscreen. This may ensure that the radar detector is able to operate at its peak performance point and provide maximum protection to the end user.
