See How to Get a GMRS License for more info. Please note that a $35 GMRS license is required (covers a family for 10 years) to use a base station setup like the one described. Our simple GMRS base station cost us about $166 to make and is capable of communicating with our family’s other handheld radios all across an urban area 5-7 miles away from our home, as well as with with our two mobile radios up to a distance of twenty miles away, using a cheap radio with only 4.6 watts of power.
Here’s how we made a powerful GMRS base station using a Yagi beam antenna that gives us more than 35 watts of effective radiated power output (ERP) from our cheap Baofeng handheld.
