What is the best Radar Detector for the RedFlex K- band photo radar ?

[GQPRO]

My country is just add a new Redflex k-band photo radar ? My V-1 can only detect it when I arriver the radar. Anyone can help ? Which radar detectors has the best detect range for it ?

Try mounting your V1 vertically and let us know how it goes. You'll also have to eliminate any K band filtering through programming options. I don't own a V1 so maybe one of the other guys can chime in here.

I have already mount it vertically , it only works little bit better.

I believe that the Stinger DSI would lay claim to having the best detection range angainst the AGD340 K-Band radar used in the RedFlex. It specializes in K Band and 34.3 Ka radar units that are horizontally polarized. The DSI uses a patch antenna with recommended mounting that would orient it for horizontally polarized signals.

Switching off Ka band on the V1 would probably boost performance a bit, but as Barryswanson indicated, turning the V1 on it's side will do more to improve range than anything else.

The folks here in the US that faced this threat also had to contend with conventional radars both on K and Ka bands. In this environment, the best detector would be the STi-R combining the superior range of the M3 with the advantage of turning off a good portion of the Ka band using band seg. Range was pretty good without having to flip the antenna on it's side which would have reduced range to standard mobile radars.

Does anyone know what parts of the K and Ka band the Stinger DSI sweeps?

Does anyone know what parts of the K and Ka band the Stinger DSI sweeps?

I believe the Stinger covers just those frequencies used in certain portions of Europe..........K-Band and 34.3 Ka, not the entire Ka wideband used in the US.

This is as close as I could come to obtaining information on the frequencies covered.

Reference page 11...........it specifies K-Band and Ka 34.3.

Do you think the X50e has the good detection ?

Do you think the X50e has the good detection ?

I think the X50e has options that would make it better than most Belscort detectors against specific photo radars used in Europe.

Ka bands in 8500 X50 Euro are segmented to several narrow bands for the best possible customization to the country where it is in use.

The Ka narrow band segments allow the user to set the detector up to scan only those specific radar frequencies in the Ka band that are of concern. This essentially allows the detector to Focus and spend more time looking at only those frequencies that are a real threat to the user..........including K-Band. This is why Belscort developed Ka Band segmentation in the first place, to give Folks in Europe a bit more range to the horizontally polarized radars used over there.

The X50 Euro also has the option to turn off Radar Detector Rejection (RDR) filtering which removes many preconditions necessary before alerting to a detected signal. This also has the benefit of improving the radar detectors reaction time as well as allowing it to alert to the weakest possible signal detected.

Operating Bands
X Band: 10.475-10.575 GHz
Ku Band: 13.400-13.500 GHz
K Band: 24.050-24.250 GHz
K Pulsed Band: 24.100-24.250 GHz
Ka (Superwide): 33.400-36.000 GHz
KaN1: 33.900-34.200 GHz
KaN2: 34.200-34.400 GHz
KaN3: 34.600-34.800 GHz
KaN4: 35.400-35.600 GHz
Ka-POP: 33.725-33.875 GHz (60 ms)
Radar Detector Rejection: 11.133GHz-12.000GHz
Laser
SWS (Safety Warning System)

Notice that KaN3 is specifically set up to cover Ka 34.3 (just like the Stinger DSI) which is the specific Ka frequency used in the Multinova photo radars in Europe.

Oh...........BTW............the V1 has a very very similar option that you might consider trying. Euro Mode!

Euro Mode is very similar to Band Seg on the e50..........it again limits the portion of Ka being swept to just the 34.3 used in certain parts of Europe. And again, this also benefits K-Band coverage as the detector spends less overall time sweeping Ka permitting more time for K-Band sweeps.

Euro Mode narrows and intensifies radar coverage, and limits it to K band plus the sections of Ka bands used in Europe and some other countries for photo radar.

I have encountered these vans and still trying to figure out what is a good detector for this.

The Ka narrow band segments allow the user to set the detector up to scan only those specific radar frequencies in the Ka band that are of concern. This essentially allows the detector to Focus and spend more time looking at only those frequencies that are a real threat to the user..........including K-Band. This is why Belscort developed Ka Band segmentation in the first place, to give Folks in Europe a bit more range to the horizontally polarized radars used over there.

Well, I always thought the same, until I tested the difference between EuroMode ON and OFF. Surprisingly the detection was better or at least the same with Euro OFF.

I made a few testruns with a 3.872 against a fixed Multanova 6F and the results surprised me. Results were better with EURO OFF.

Just a theory: With Euro OFF the V1 sweeps from 33.4 to 36.0 GHz (2600MHz), but with Euro ON the V1 has to scan from 33.70 - 33.90 GHz then 33.96 - 34.04 GHz then 34.16 - 34.44 GHz and then from 34.56 - 34.64 GHz.

Maybe it takes more time to seperate the KA Band into different segments than to scan the complete 2,6 GHz Ka band?
Any thoughts?
