FCC ULS database searches are now back up and running. Found 45.42 MHz as an active license for Hawthorne. Former PD frequency. License good until 2024; last renewed in 2014. Perhaps this is their "operations" frequency.
I guess its possible they use lowband, but I highly doubt it. Besides most departments not even having the physical infrastructure for it anymore, a lot of towns that have it licensed don’t have radios or antennas in the patrol cars anymore.
Ringwood still has lowband technically licensed. None of the cars have lowband antennas, or have lowband radios from what I could see. They use NXDN mode for their tac ops.
Wanaque a few years stopped putting lowband in the newer patrol cars. One of the dispatchers told me, “it’s just another radio that takes up space in the smaller newer cars.”
Bloomingdale was the latest to ditch lowband it seems, once they went DMR. None of the cars have lowband antennas now. Even their newest cars did have them. But from the cars I saw they are all gone.
And AFAIK, there is no “low profile” lowband antennas. Oakland, before NJICS(still have the antennas), and West Milford all had the gigantic whips.
