Buried in the long testing thread I mentioned I did a brief test with the Spectre Elite and I was detecting the R7 at around 100ft in both the rear and front of the target vehicle with the R7 on the windshield with Spectre Elite at full sensitivity.
We plan to test some other Spectre Models and see if there was a difference with some versions over the others. I did mention my results to engineering and they are expecting the full retail units to perform better since some changes were done to the horn to improve shielding after the original pilot samples we are using were created. They do expect to have more leakage on the R7 then there is with the R1 & R3 due it having a larger horn. I might need to take it apart to see how larger it is over the R1 & R3 because now I am real curious.

We of course will test the retail units when we receive them which at the earliest would be between April 5th but I always plan for some customs delays so I still say between 4/5 to 4/15 to be safe. I just want everyone to be aware that while they still have less leakage than its dual antenna competitors (360, 360c, V1) it does have leakage that some in banned areas need to be aware of.
Wondering if they use kevlar as shell to hide rf leakage if that would work ? Should ask uniden @bestradardect.

I doubt they will be able to get the R7 undetectable within 20'
We will re-test the final released units but even the R3 can be detected at that distance on a direct view but the benefit on the R3 is that its only detected in one direction and police are not driving head on to towards you. R7 adds rear leakage as well having dual antennas so having an officer pull up behind you will set off a RDD detection.
Unless uniden uses alluniunm foil inside to stop rf

Aluminum foil
-- Double Post Merged: --
@UnidenSupport are you able put Aluminum foil inside the casing to stop the leak of rf signals? Since Aluminum foil does stop rf signals.
I said what mainly in hopes you weren't sincere on the idea. You would not want to put aluminum foil inside the detector.

You should open yours up and modify it yourself. Be sure to cover the front and rear horn since that's where most of the leakage comes from. If your interested in aluminum foil you should really try brass screen. With some practice and attention to detail you could make the perfect Faraday cage.

You may even be able to make some money modifying other people's detectors for them.To be the most effective, make sure to use Gold foil, not aluminum!

That's true, there was a favorite modder on RR that people sent their scanners to. He was doing good business but is in prison now. There's a big hole that still hasn't been filled.

No you would actually want to buy aramid fiber material and line the inside of the horn. It will attenuate the leakage. But you have to polarize the fiber strands so they are lateral to the horn otherwise you will block incoming RF and let out the outbound RF.

According to this What are the differences between aramid fiber and carbon fiber? : PITAKA Help Center carbon fiber is better at blocking RF albeit although it doesn't have as good of tensile strength.

Aramid is the fibers commonly referred to as Kevlar and Nomex. You wouldn't want carbon fiber because it poses no polarity. Aramid material will act a low pass filter to capture the escaping RF if aligned and stranded properly (expensive) without affecting the detectors nominal performance unlike carbon fiber

Man, I learned something new today. So a custom made Kevlar case polarized horizontal to the horn could be the trick! There's a business model; get the molds custom tooled and make your own polarized Kevlar cases. That would be a great aftermarket opportunity!

It would be very lucrative for someone looking to become an upfitter for RD’s. You could gain a nice niche market for people who need the best RDD immunity possible

The tooling cost would probably be minimal based on projected revenue.

With all the people raising concerns for immunity lately yeah I agree. There is plenty room to have ROI that is more than satisfactory

Make the case faraday cage to stop the leakage
Well I understand the concept, just not the practical application. That's why I'm looking for a proof of concept.

Have the case made out of the same type stuff as faraday cage
