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.

I have professionally installed lightning rods all over my roof. But I am told even a near strike can charge the antenna and fry my system. That's never happened to any other equipment in my house tied to the cable TV or phone system in 4 years in the lightining capital of the western hemishere, central Florida.
