Enter GMRS repeaters, which act sort of like cell towers or relay stations to pick up our signal and send it out farther than what was ordinarily possible. GMRS repeaters are often located on high mountaintops, such as the 462.600 machine in Silverton, CO, and some may cover hundreds of square miles.
Let’s say that you’re headed out with a group of people to spend a few days exploring a certain area – hiking from a central base-camp where there’s no cell phone reception. A self-contained repeater unit could be set up in camp in just a few minutes and serve as sort of a relay station, helping handhelds that wouldn’t be able to reach each other to communicate. Temporary, portable GMRS repeaters can be very useful for things like off-road vehicle events, cross-country marathon races, large outdoor events or anywhere else where a central “relay” station could help radios reach each other more effectively.
