A mobile alert transmission system for an emergency vehicle, includes a switch configured to activate an emergency alert. An antenna is configured to emit radio-frequency waves that transmit the emergency alert. A signal generator is electronically coupled to the antenna, and is configured to generate the radio-frequency waves and to provide the radio-frequency waves to the antenna. A controller is communicable with the signal generator and the switch. The controller is configured to receive a command from the switch to activate the emergency alert and to cause the signal generator to generate radio-frequency waves.
