We’ve all see those tall antennas on top of cop cars or on older cars. But i never understood how it worked or whats in them. Are they literally just a long flexible wire? Does the signal emit from the top or throughout the length of the wire?

Yes, that’s literally it. If you have a smartphone with radio, you can notice that the radio works only with headphones plugged in, because it uses headphones (long flexible wire) as antenna.
