Helicopter-Mounted Horn System vs. LRAD 500X-MMT

Pennsylvania State Police used a helicopter-mounted horn system in a dangerous low-altitude attempt to broadcast warnings to tailgaters before a Penn. State football game on September 30, 2018.

The LRAD 500X-MMT has a 2000-meter air-to-ground communication range and broadcasts voice messages that are clearly heard and understood above rotor wash and background noise.
