A rooftop antenna, while well-suited for receiving television signals, can also draw lightning in inclement weather. A lightning strike to a TV rooftop antenna can be dangerous, both to the antenna as well as to the electronic equipment connected to it.

Due to the way sound travels and how various objects, such as mountains and buildings, interact with sound waves this is not the most reliable way to predict lightning distance.
