Weird positioning of Radar

[focalcivic]

I was driving on the PA turnpike on Saturday and noticed that the cops were sitting right behind bridge underpasses, with the car parallel to traffic with the radar antennas on the top of the back window out side of the car pointing towards traffic. I don't understand how this can be effective since the car was sitting in the direction of traffic, almost like they would need a mirror to see the oncoming traffic as they try to get a reading. The band was K.

Here in Cali, the CHP does this all the time. They sit on the side on the freeway looking out their side mirror, then take off a the next speeder they see. The only differences are that the radar antenna is mounted inside the back window and the band is 34.7Ka.

Yea.. Kinda odd to read that the radar gun was OUTSIDE the car. Raleigh cops here have two sets, one on the front and back windscreen. But, they are both INSIDE the car.

Look like this?:

That is normal.

Not necessarily outside of the car, but yeah, they can clock you anyway they can get you.

There was a picture of a motocylce cop with custom rear antenna on the back of his bike. I would not have believed it unless I saw it. A year later I actually saw a motocycle officer with such a setup. Unbelievable!

I remember lots of exterior window mounted radar back in the day of the old MPH K-55 x band.

I always wondered how a cop could postively ID who was speeding when they were facing the same direction as traffic? Kinda throws the theory of "tracking history" out the window. :roll: (no pun intended)

Yea, normal... I'm sure it would be pretty normal to see the cop chase down a car going 100 MPH with his bloody radar gun sticking out his window... Hmmm, yea... Why doesn't the cop just leave it attached to his windscreen inside his car. Maybe he wants to give his radar gun some sun, awww, poor lil radar gun, all it sees is fluorescent light.

Hey Seffrican

I think these were set up to ease fears of cancer problems from having the gun in the vehicle... as when it is inside the vehicle there is some RF radiation that is bounced around in the cabin.

The reason it was outside of the window was because he was sitting towards traffic and then i guess looking in his mirror as traffic approaches, you can not see the police car until you are right on top of it. DJ yes that is how it was set up. I picked it up easily, I was doing like 90 or so, then picked up the K I went down to like 60 and the cars behind me were like what the hell was I doing LOL.

Sounds like to me that the RADAR unit is used in more than one cruiser. Using a window mount is easier and or quicker than mounting it on the dash. I use to see this set up all the time back in the late 80's, very early 90's. Especially around Virginia.
