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.
Don't kid yourself--you are NOT safe outside. Following these tips will not prevent you from being struck by lightning, but may slightly lessen the odds. If camping, hiking, etc., far from a safe vehicle or building, avoid open fields, the top of a hill or a ridge top. Keep your site away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of trees.
