Ways to Keep in Contact During a Natural Disaster

2 Way Radios
In the event cell towers are down and landlines don’t work, a set of two-way radios might be just the ticket for staying touch. If you remember two-way radios as a static-filled but mostly frustrating toy from your youth, think again. New versions of this communication option can have a range of 30 miles, which should meet the needs of most families in the average urban situation. Some features to pay attention to when shopping are battery life, channel selection, range, privacy codes and size.
CB Radio
CB radios, or citizens’ band radios, have been used for decades by amateurs to communicate with people across the state or around the globe. Most people are familiar with the version of CB radio installed in truckers’ rigs. These are similar to portable two-way radios. Another CB radio option is a base unit, which is installed in the home. Base stations can communicate reliably up to about 30 miles, although this can extend to hundreds of miles when atmospheric conditions are right. Because a CB radio has its own antenna, you don’t have to rely on a cell tower or telephone company land line to stay in touch.
