@Andrew21
Any chance we could pin this please. I often refer fellow NZers to this, and would be good to have it at the top easily accessible for future reference.

Thank you.

Just wondering what type of Ka unit you were using and the power as my Stalker Dual DSR front is twice the power of my rear gun. My calibration is only 2 months old so the cert will be accurate. So with mine being like this my front gun reaches 25% further than the rear. Track days the rear gun is better as I am reasonably close.

Handheld stalker ATR, I think there are some photos of our setup in one of the videos.

That's cool, do you know the power output? Yours is more handy than mine. I can lock 2Km out but that's useless. What is interesting is different makes of motorcycles are not the same at getting a lock on. For some reason my Carbon Fibre front seems to absorb most of it until about 100m away. It is exactly current issue without the lockouts for NZ. Actually one gun is slightly hire in frequency to the other as not to cause interference when both are running.

Interesting regarding the different motorcycles, we in general found that bikes were hard to get a consistent lock on at any great distance with both radar and laser. Maybe just our technique with the laser.

Unsure about the power output @radarrob might know.

Got a confession to make, years ago I purchased one of those Mirage 2001 stealth units that are meant to block the radar, well at 500m on my MC he got me because it helped him not me! Bit of crap but had no way of testing it except a ticket. Made me shine like the sun!

Yikes!

Looks like you’ve done plenty of research since, and have the equipment to test it out as well!

The RD's I have had a look inside seem to be for Linear polarization and I can understand this as you can please everybody. In NZ the Stalker use Circular polarization which is RF quiet but if the antenna was set for them then it wouldn't work with camera vans as the are Linear polarization. The difference in sensitivity is a lot when detecting. Most alerts come from bounces of other cars. Camera vans are normally set up so there is nothing reflecting in the beam. At the angle camera beam strikes the side of a car the residual reflection is not going down the road to alert you.

Redfex uses a slightly different method but the angle of the beam is set at at angle to make it very difficult to detect. Look up about reflection angles of mirrors, most of it can be applied to Microwaves within reason.

So, if you want to get good detection of Circular then the RD's antenna has to be designed for it. Either right hand or left hand. Same with Linear, Vertical or Horizontal. Set to the wrong polarization and the RD is basically deaf.

The software in the radar units are very smart but as with anything ( Windows operating system is a good example ) they all can be defeated but the average RD user is not a hacker nor can the be expected to. What can be done is modify you RD to receive what your most interested in. Set for Stalker would be useless for Camera Van etc.

My interest is in other Microwaves, it just happens that the knowledge easily transfers over to Cop radar. There is not much spare time at the moment but ask and I will try and help.

Wow stellar effort guys!!! And for a guy that just really needs an on off button to get things to work, I’m happy to say it was very easy to understand,! :)
Also, from what friends WITHOUT rd,s were recommending compared to the results, I’ll be going a different way!
Thanks for the save

Has anybody tried to turn their RD 90 degrees to catch the Horizontal beam of Redflex? If you know of a camera try this and tell me if your detection distance increased.

Look at the angles and shapes and RF absorbing coatings on Stealth aircraft, the H2 isn't a million miles away from that.

It's been done with V1, and it works. But according to other posts it reduces Ka range.

Like @LouG says, apparently so. There are a few youtube videos out there as well, but no substantive testing as far as I know.

Here's an excellent explanation...in short, you'd increase the reception of the horizontal Redflex but lose detection distance for radar that is polarized differently..

I think you kiwi's are lucky to know the redflex is attached to a van which sticks out like dogs nuts on the roadside. In oz it could be mounted on anything. Commodores are common, I've also seen an SUV, and nearly got nabbed by one on a Ford ranger looking Ute. The Ute was jacked up on its suspension, so I could see right under the car, and noticed a tripod like thing in front of it, that didn't look "normal".
So advice on detectors for this would be worthwhile posting for your neighbours across the water in Oz. It's getting difficult here! We need all the advice and help possible. Cheers for the info/testing you guys have done. It's killer!

The information regarding polarisation is not valid for NZ. Redflex uses Horizontal and Stalker is Circular so turning your RD makes no difference here, I dont know of any Vertical polarized radar in NZ, does anybody have valid information?

Redflex is like the holy-grail for radar detectors, not even the Stinger has cracked it yet. Hopefully the R7 will be useful, but being a bit leaky, probably not safe to use in the eastern states.

Detection of Redflex is easy but commercial detectors are a compromise, they are made to do everything. The Chinese cheap V7 has been modified by myself to do Reflex only and it works great. Before it was hopeless with false alerts and almost deaf to Redflex.
