Unmarked cruisers

[dguy]

I noticed this on my way in to work this morning...  a couple of "unmarked" police Impalas had unusual-looking protrusions on the trunk lids.

Two circles, each perhaps 1" high.  One on the left-hand side and approximately 6-8" in diameter, one on the left which is much smaller.

I've never seen them before this morning...  anyone know what they are?

Maybe a new style of antenna?

Slammed the trunk lid on a perp's head??

I would not know being a law obeying citizen I do not feel the need to look very closely at police cruisers, instead I drive along paying attention to the road and being extremely courtious to my fellow drivers. Dan

Cops are up to something.....I have seen those also!

WTF are they?!?!

[dguy]

I'm inclined to think like WillEV.  I'm guessing (and I mean guessing) that it's an antenna of some sort.  Of what sort, who knows?

Could be GPS, communications, or even some sort of rear-looking radar that's more subtle-looking than the beer cans they sometimes strap to the sides of the cruiser.

Yes maybe a GPS unit. Could be hooked up to a central monitoring station so they know where all the cruisers are at all times ?

If it's a GPS unit antenna, the antenna chould be anywhere.  Why put it on the hood?  It's got to be the worst place to run a wire?

Talked to a child friend who is a now a constable, those little disks are the new attenna styles, one is for the gps/carr marker,  the other is the radio. supposedly this style is more reliable and has a greater range then the old stick-in-the-air ones.
