Combo Blinder / AL-8

**Eloi** · 11-05-2007, 09:25 PM

Here is what I did with 2 al sensor + 2 sensor m-20.

To have max of protection : 1 al + 1 blinder for front , same in the back .

Is this a good combo , I use this approach if I should explain those boxes on my car , Leo here are very curious , so I can show the parking features front and back ...

Is this a good idea ? Any suggestion to improove my setting ?

All depends. What type of car?

^ +1..... More details, please.

Also, please document/depict where you've put the respective heads from each jammer. This can also affect performance.

More details, please.

For the back , I know the tint glass impede , but I had absolutely no choice , I check with a cam , I see the glow , loss is around 8%...

Thanks for your help.

That AL head will be too low. it won't give you proper protection and will probably give pretty quick PT at just about any distance except maybe over 1000'.
i'd recommend it above the plate, just below that black area that is below the symbol.

The Blinder head... ah, won't do too much, mainly possibly help with some higher overpass type stuff. if that isn't a concern, then be sure to mount it slightly below level for a bit better performance.
ideally if it were inside above the handle on the glass, it would help out more, you just may need to get creative in mounting/running the cord.

good luck.

Like you know anything about stealthness

Hmmm, just thinking out loud, but here's a suggestion/idea.

Put one AL head in the rear, above the plate, with the receiver favoring the passenger taillight. If you plate is shot, it should provide protection. It probably provide the same protection as the AL/Blinder combo you suggested.

Since I don't see the Blinder head in the back being much help, put the two Blinder heads in the front grille slots, preferably as close to headlights as possible, in the top or middle slots. The front AL could go in the space under the black box you drew. At further distances, it should protect a great deal of the front. As you get closer, it should protect the CM well, while the Blinders would protect the headlights, and some of the hood.

Again, this is just me "spitting out" ideas.

Thanks for all the tips .

To help my ''poor'' location I deflectorised my plates,
the back blinder is tilted downward , so the back al is tilted upward slightly.

In fact , there is no space close to the back plate unless half the head is out , therefore too obvious.

I am bit paranoid since they don't yet shoot at the rear , but they
surely will learn anyday. :shock:

I must confess that I prioritise steathtiness more than full jtg , cause I don't run excessively over psl ... :wink:

Just that I prefer spending my money in cm than tickets ...

I'm inclined to go with both RacerX's and ELVATO's suggestions.

Get that rear AL head up higher - stealth, while necessary, won't mean a thing if you get a ticket, which is particularly troublesome if the simple fact of having an AL head out-rear gives you a sense of false-security, even if you don't go too far above PSL.

I see two potential areas for relocation - one is the black trim just above the "overhang" for the rear plate (as you have cited that having the rear head within the overhang, directly above the plate, is not possible due to visual-signature concerns), and the other is the stand-off for the rear windscreen wiper. I would investigate both whether or not cutting into those areas would be possible (i.e. what's "behind" them, and whether or not the AL head would fit) as well as how much it would cost to source a replacement trim piece to-match (for your vehicle's future resale needs).

I also agree, as I cited above, with ELVATO's sentiment in that the rear Blinder head isn't going to do much - at all - for you. There have been member-independent tests of other comparable laser diode-based jammers, with one head being barely enough for the rear even on smaller vehicles, and with two heads offering still yet barely sufficient/acceptable protection. Using this data, it's easy to extrapolate to the thought that a single LED-based jammer probably won't be very effective at all, and again would only contribute to a false sense of security.

Instead, I'd, as ELVATO suggested, relocate this head to beef-up frontal protection, which, IMveryHO, with your vehicle's paint-scheme, physical frontal-area, as well as hard-points, will make it difficult for a single AL to offer "complete" coverage. I would indeed, again as ELVATO suggests, separate the two Blinder heads as much as possible on the horizontal plane (leaving the AL to guard center-mass, mounting under the front plate to effect best concealment - but be sure to mount the head at least "flush" with the plate, so as to give it best jamming potential) and to try to use them to offer effective coverage for each headlight.

The idea of offsetting either the Blinder or the AL head, as you've indicated in the previous picture, is in my view an extremely bad idea. serg, at one point, used a single-side offset mounting location for a single LPP head. This setup later revealed, during independent testing, to offer the farther side considerably less protection than one would have expected, and made for some rather disappointing PT numbers. Not surprisingly, this kind of "hole" on the off-side was totally eliminated (effecting a JGT solution) once he also put another LPP head on that side.

I don't think you can offer good protection for the rear and the front with that set up, that suv just has to much surface area. you could ether 1. scrap the blinder (or put it on another car or ebay it) and put both AL on the front. 2. Put the blinder and AL on the front. 3. or like others suggested put the blinders close to headlights and one AL in the middle, however putting that other AL in the back by itself will not be enough to provide good protection.
