Hello, I've noticed that most of the time antenna on public safety vehicles are located on the roof in the middle, or on the roof near the rear window. Depending on how many there are. Our public safety vehicles have two; so one is on the left its a VHF antenna for the statewide digital radio system and one if on the right; it's an antenna for the scanner. My question is, does it matter where they're mounted? I've seen them on trunks too, even on front hoods. Thanks.
