As always, there are no guarantees when it comes to lightning. But this new gadget appears to go a step beyond good grounding and surge protectors to keep your communications electronics alive. Turning the $60 Lightning Guard 200 to “off” will break all of an attached radio’s connections, including the coax shield and the negative battery, and then tie them together and also to a ground plate if available. Of course that means you can’t use the radio during a storm, but this technique is said to protect against even notoriously erratic side flashes. Models designed for other electronics are in the works.
