We have, well, a variety of law enforcement vehicles in Houston, but I’m curious about something I’ve noticed not only with HPD cruisers, but those of other cities as well. What’s the deal with the occasional (definitely not all) cop car you see with 7-8 little antennae on their roof? Are the roving command centers, or some such?
Some are used as repeaters to increase the range of portable walkie-talkies, some are used for the NCIC computers which report data on a persons criminal background. An array of four antennae in a square is a Lojack array. There may be others as well.
