The rangers at our local state park are encrypted. They have been using the standard antenna for the state system for awhile. I now notice another antenna on all their vehicles. It is black and square. Can someone tell me what this is for?
That's the antenna that Harris sends if you order the WiFi/LTE/GPS option with your mobile radio.
Could be used for a number of things:
-More recent high end public safety radios will not only do traditional LMR radio type stuff, but they'll also have an option to link back into the P25 core via LTE networks. Helpful if LMR coverage is not available everywhere.
-The Harris radios can act as a WiFi hotspot if they have the LTE option.
-The GPS portion is useful for vehicle location to dispatch.
Or, as others said, could be used for their Cradlepoint modems, or multiple other options.
The antenna in front of the lightbar is a multiband VHF/UHF/700/800MHz antenna.
