Was visiting a local big box store this morning and as I was leaving there was a marked PSP CVPI (from the Carlisle Barracks) parked at the door in that "special" way that they like to park. What caught my eye was a RADAR antenna mounted inside on the rear parcel shelf just to the left of the center brake light. There was also a front antenna in the usual place for 2 or 3 piece RADARs just to the right of the driver's A-pillar/spotlight handle. I glanced inside but could not locate the display or remote control but am pretty certain the antennas were Decatur K-band units (all black housings, opaque white lens surrounded by a silver ring.)
While certainly not new, (and very familiar to drivers in most other states) what's concerning here is that this configuration is commonly used for moving RADAR which of course is illegal in PA at present. Until now, the only non-handheld units I have seen PSP use (over 30 years of driving) have always had the antenna temporarily mounted outside on one of the windows to suit whatever location the officer chose to sit at. That obviously costs less so what other reason could they have for using a permanent mount 3 piece unit now? Certainly not to shoot people up the rear from an overpass!
