    I believe it's the beam width and recently ran across an article illustrating this but can't find it for the life of me.

    Anyone else know where there's an article regarding beam widths?

    R1/3. Lol. This thread was started before they came out.

    Lol. I know it’s old.
    Look through Vortex’s videos. He did a really good one on the question your asking. I just watched it a few weeks ago. It’s an older video, but explains it very well.

    All Ka radars made today are 12° beams except the bee 3 at 13°

    It's the high frequency that makes it harder to detect

    On top of that
    35.5 can do odd things in the rain and with tougher terrain
    Especially when larger angles are introduced

    @Duke295 did a lot of 35.5 research that's scattered through threads on here that explains much better details

    There's that one... but it really doesn't cover your question. There is another one that is even more detailed, maybe on Vortex's website, that gets into each frequency within Ka band and really gives you the answer to the question you raised.

    After a cross country trip 4600 mile, round trip I found my segged redline seems to be just a smidge better than my R1 on 35.5 while my R1 is a tick better on 34.7. Both of them sucked at K band filtering on this trip! I ended up turning K band off on the redline, and going all the way down to city mode on the R1 with K filter on! Both of them kicked supreme @ss the entire trip with not even a trace of interference .I'm glad I didn't sell my Redline like so many others did! It still is one hell of a detector! I didn't see enough 33.8 to form an opinion on that. I also didn't see even one legit K band alert.

    I guess most or all of your encounters could’ve been of the straightforward variety, but if your Redline is beating your R1, that’s likely evidence of interference right there.

    I said they are pretty much even. I had some encounters of up to ten miles or more! On straight up encounters,they are tit for tat,off axis the R1 wins just like it should. If anything,the R1 should have hurt the Redline,but it did not,not even once! ALL of them were CO encounters for MILES and MILES! When I ran my redline with my V1 before band seg. came out, my Redline slept like a baby ALL the time and lost on every alert.Both the R1 and Redline were pit bulls on each and every alert! There is no way they could work like they did and have even a trace of interference! I have several STUPID videos to post when we get them sorted out.This was not some little test,it was a six day 4500 plus mile trip! If there had been ANY interference, I would have been all over it!

    My sample size is one, but I've never noticed any deficiency on 35.5 vs. other frequencies on my R3.
    This morning I came across a cop running it from a static location, so I know I detected at exactly .7 miles, on-axis, with a big arse hill in the way. Not exactly a "moon sniff", but still waaaay more than enough time to check down to the speed limit, and like I said there was a serious terrain impediment cutting that range down.

    The wavelength difference between 34.7Ghz and 35.5Ghz is trivial, 8.64mm vs 8.44mm. I can't imagine that would have any noticeable affect in the way the wave propagates through rain and terrain, everything else being equal. In testing the guns used typically for 34.7 testing are the Stalker ATR (50 mw nominal) and Stalker II (25 mw nominal), vs the 35.5 guns which are 20 mw for the Kustoms and 12 mw for the Decaturs. So makes sense that 34.7 test results would be typically further. In real life I don't see a huge difference between the 25 mw state police stalkes and the local Kustom 20 mw guns here. It would be interesting to actually test the output power of the different guns, because all we really have are the published specs to go by.

    Unfortunately all that info is incorrect
    Kustom 35.5 is 25mw
    Same power as stalker dsr

    and the higher frequency you go up in the ka band the more difficult it is for detectors to see

    I see a 50% range loss stalker FF handheld vs kustom 35.5

    You are right about atrs making detectors shine

    I don't like that

    Most RD detection circuits are designed to have their best detection on 34.7 because it is in the middle of the very wide Ka band. You might say they are cutting corners. Some RD manufacturers like Uniden, (with the R1/R3) and Escort (in the M3 models) have figured out how to achieve good detection on both 34.7 AND 35.5 GHz. Having said that, detection on 35.5 will still be shorter than on 34.7 most of the time, all other factors being equal.
