Is there such thing as "too high" for the RD to be mounted?

Assuming each scenario with the RD's paralled to the ground. Would be there a point where it's too high for say a lifted truck with the RD near the roofline?

Right now on my Highlander it's near the top but wanted to know others input...technical reasoning I suppose.

i say no. the higher the better, and a few people @KASHER1979 has his on the top of his soccer dad van.

I have a smaller car, ford 500, and i have my redline on the headliner.

Imo it will give you a better chance of seeing over the crest of the hill, or seeing above other cars etc.

laser in theory would be bad, but you already know with any radar detector catching laser ahead of time is like seeing a pink elephant or unicorn

Not really, higher is best due to the configuration and properties of the transmitted beam and the fact that the only situation where that might possibly even remotely be an issue would be one was 5 feet from the source LOS but then total signal strength would rule the day plus Blind people that wouldn't see a LEO five feet away should not be driving!

Being high up also makes sure there are no vehicle parts blocking the receiver's receive path and gives the greatest percentage of direct LOS plus a higher percentage at reflections.

Roof mounted detectors are the best for long range detection in my experience. Even a weaker receiver can beat a strong detector that's in the cabin. I have seen it time and time again.

No matter how strong the Windsheild detector they still can not consistently alert before my roof mounted 9500ci due to the position.

If there are environmental factors like a metallic tint brow on the windshield, then yes.

Laser detection would be your only 'loss' by going high. The gains outweigh the losses though. I keep mine tight against the headliner.
And if you have a V1 it should pick up every laser hit even tucked way up high.

Have you done any testing with it in the bumper? I wonder how much of the benefit is height vs not being behind glass. My Redline on the windshield was less sensitive than my STi-R in the bumper despite them being the same in Escort's faraday cage.

kevin has a super detector that can beat any detector made.

Yes I tested in the bumper. Still much better on the roof. My 9500ci still beats the strong WS detectors like the R3 and R7 because being up there. Also just so you know it is a hand picked super stong 9500ci that I picked from searching and testing years ago.

As another datapoint my BlendMount R1, out sniffs my bumper mounted NR/DSP.

I have the luxury of only running 34.7.

Due to the fresnel zone of a radar signal; the farther away from the hood of the car, the better. A detector that doesn't lend itself well to being mounted against the headliner is a detector that was not designed with a basic understanding of radar propagation. (<- That will stir up things)

The fresnel zone is an area above and below (and to the sides too) of a line of sight signal. The more space allowed for this area (to the point of diminishing returns) the longer the signal can travel.

In the case of a superheterodyne detector which transmits and receives, it will perform better if it's not resting near a flat surface in front of it obscuring either it's line of sight or it's near line of sight.

Dang... Even against the Uniden R series?

Take a look at many of the tests done that include the R series detectors. They aren't winning by huge margins.

The only reason my unit is beating the Rs is because it is a hot M3 up high and outside.
