I am trying to figure out what type of antenna (up against the rear window) is can anyone help?

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

My first guess is it is a combined GPS and LTE antenna for their MDC system or a multi-band antenna for an APX type multi-band mobile radio for radio interoperability with allied agencies statewide.
Looks like Cell and Data.

Looks like the old fashioned "inverted F" that metro busses used to use. They used that at rather low FREQS, high band in those cases where they did not want a tall antenna as a 1/4 wave would be too tall. They are rather wide band considering how short they are. They are wider bandwidth than a helical of the same height would be.
I'm guessing this only because it's low height and long front/back. Here's what the inverted F schematic looks like:

I believe the California Highway Patrol (CHP) also run the same type of antenna and based on the other antennae mounted on the car and they were easily identifiable on what they were for, that left GPS and LTE for their MDC (Data). The CHP used to run the hockey puc antenna for their GPS and LTE for the MDCs. The manufacturer of the hockey puc style antenna may no longer be available.

GSP migrated to LTE on SouthernLinc for their primary communications, using LMR radio as backup. The antenna is very likely used for the LTE connection from the Harris radio, along with GPS for location data.
Many of those antennas will support multiple radios, so possible it's also used for their mobile terminals.
As for exactly which brand/model, that would take a lot of searching...

I'm thinking you do a lot of installs. It's my understanding some of the PD's around me have dashcam systems that automatically download video over the air to a server or whatever at the station. No touch automatically. If you're familiar with what I'm talking about, would you share a picture or two of what those antennas look like?
Thanks.

We have that, but the antennas are built into the recorder package. Not an external antenna on the vehicle. We've got a couple of wifi access points near where the cars are parked and they just upload when in range.
