One of the joys of heading out into the wilderness is getting away from the hustle and bustle of civilization. That usually means being out of reach of cell phone towers, leaving you with no means of communication in case you need help. The answer is a satellite two-way radio, also known as a satellite phone. Below is basic information on how these radios work and things to look for when purchasing your communication device. 

How Do Satellite Two-Way Radios Work?

Cell phones rely on "line of sight" communication with land-based cell towers. As you move about, the cell phone connects to the nearest tower and even changes towers in mid-call. Satellite two-way radios communicate via orbiting satellites far above the Earth's surface. That makes them the ideal communication choice for remote areas, on land and in the middle of vast oceans. You must still be able to see the sky to communicate with the satellite. Trees and large buildings can sometimes block the signal. Satellite radio providers usually have multiple satellites in orbit to provide better coverage.

Things to Consider When Choosing Your Satellite Radio

Check the Size and Weight

By definition, backpackers limit their belonging to what they can comfortably carry in a backpack. Compare the different two-way satellite radios to see which one is lightweight but still has the desired features. A satellite phone that has an antenna that's roughly the same length as the body usually provides better reception. As an example, a typical satellite radio might be five to six inches high, a little over two inches wide and a little over an inch deep. The antenna, which folds down when not in use, would ideally measure between five to six inches when extended. The entire two-way radio usually weighs well under a pound, perfect for keeping that backpack lighter.

Study the Satellite Radio Features

Two-way satellite radios offer various features that might interest you. Pre-set calling tones, similar to ring tones on a cell phone, let members of your group know it's you on the line. This is handy if you're on a group ski or back-country trail hike and get separated from the others. A keypad lock keeps settings from being changed and calls from being accidentally made. The weather radio feature is especially useful in backpacking scenarios. Communicate with NOAA weather stations to find the latest conditions and forecasts for your area. A hands-free option also comes in handy. If you're paddling a kayak or skiing down a mountain, ski poles in hand, sometimes it's difficult to free up a hand to answer the phone.
