Valentine 1 mounted vertically against Multaradar C

[Clandestine]

Hello, guys, this post is mainly awaiting the replies from our friends from flitsservice.nl as they have a lot of experience with mounting the V1 vertically against Multanova. Of course all other inputs will be highly appreciated. I have a problem now: in my country both radars are used, Multanova 6F and Multaradar C. By mounting V1 vertically I could dramatically improve the range on Multanova 6F photo radars, but what does this do for detection of Multaradar C? Will it decrease it? I don't remember exactly but I think I read somewhere that these two radars use oposite polarisation, so if my fears are correct, there is no way of detecting both types with the same detector properly? I will appreciate your reply, Martijn. Kind regards!

You should also post this on Flitsservice.nl/International Discussions Forums,if you want their feedback.

...and you're right,MultaRadarC has horizontal signal polarization,opposite to Multanova 6F,which is vertically polarized.

I was thinking of how to make V1 a truly perfect detector, even for Europe, would it be possible to implement a software switch into the firmware (similar to what they did when they implemented Xband detection in Euro mode), which will enable the users to use either vertical or horizontal polarisation detection in Euro mode per users' choice on Ka band? Wouldn't that be something, ha? For example, the option K could read: Use vertical polarization detection on Ka Band On/Off
Do you guys this would be possible through software programming? Maybe Professor Jim could give us a thought or two...

I hope someday I get a chance to test the V1 vertically against one of those Multinova cameras. That would be cool.

Oh, it's surely worth placing it vertically... From my recent experience the detection range increased from 200-400 meters when placed horizontally to 500-800 meters when placed horizontally. That's basically 100 % increase of detection range. This helped with Multanova 6F and Ramet AD9 stationary radars. The only problem is that K band photo radars like gatso and multaradar C use horizontal polarization and placing V1 vertically will decrease the range on K band. One of the possible solutions would be to have two V1s mounted, one mounted vertically with K band disabled and another one mounted horizontally with Ka band disabled. Providing that the two V1s wouldn't interfere with each other too much...But enabling the vertical polarization with a software switch would definitely be the best solution. User could then decide whether he needs it or not...I know this solution would not be useful for ordinary lamers, but for us geeks it would definitely represent a few more reasons to enjoy our protection and to benefit from it even more.

Have you met Multaradar C yet? What distance your V1 gave you?

Clandestine,I can assure you that the polarization problem has nothing to do with software.VR cannot solve this with software update,they would have to change horn design and maybe even add a special waveguide,to counter vertical and horizontal polarization effect.


On the picture below is the latest "invention" of Enerby (one of the Flitsservice.nl guys).Inside is a Bel975's (M4)antenna,but it will also work with (S7)Bel966 aka Target 660EVO's antenna.He designed and made a lot of RDD filters and horn extensions,but this one is a Dual Bandpass(24,125GHz & 34.3GHz) RDD filter with -20dB/cm2 gain and the best of all,it's polarization proof(he calls it Multi polarized).It doesn't matter how you mount it,V or H,you'll get the same results.I think that he designed this,because in Holland they have the same problem as we have in our Country,V and H polarized Radars.
FYI,this modification costs €215,turn-around time is 3-4 weeks,S&H is €15
Dimensions are 200x75x38mm





Picture below shows peak detection in relation with freq. and which freq. can pass thru Dual Bandpass filter.

On MultaRadar-C,I get about the same detection,as I get against Multanova 6F,sometimes less.Normally,on local roads,it's between 200-350m,on highway I get a bit better detection.
