Can the ThunderBolt work inside as well as outside?
The ThunderBolt is designed to work nearly as well inside most buildings as it does outside. However, certain types of buildings with metal walls and roofs might cause a loss of sensitivity in normal storm detection. A general rule of thumb is that the ThunderBolt will operate normally in any building that allows reception of normal radio signals.
