Coaxial lightning protection for TV tuner card .

Please note that this device (and every other device we carry) does not offer protection in the event of a direct lightning strike. A direct strike will likely vaporize the antenna system and destroy everything attached to it. If you know a local thunderstorm is imminent the safest thing you can do is to unplug both the antenna feed line and the power cord from your receiver.
