as anything with EM and metal, the signal will be attenuated but it will get through, you will still get directional detection but of course with reduced range.I was wondering about R7 or any other dual horn RD usage in a car with limited or no rear glass visibility.
For example, I have a sedan BMW 440 on which the top of rear glass is about 6-8" lower than the top of a front windshield.
I have my R3 mounted at the very top of the windshield, practically hitting the ceiling. This is the best spot for RD in this
car IMO given the fact that the windshield is very short top to bottom.
If I install R7 in the same spot, how much of its ability to detect threats from the rear will be impacted?
I would not want to move my RD lower on the windshield since that would obstruct the view significantly.
Would it make sense to run R7 in the vehicle with no rear visibility, such as cargo van?
So yeah it's not a deal breaker, you will just have to drive with a bit more caution then someone who has a full rear-view glass window. A 34.7 Ghz radar has a wavelength of 87cm so in reality the thermal heating strips actually attenuate your rear detection due to the 1/4 wave spacing (each spacing depends on manufacturer)....but the detection still occurs.
