They range of these radios is amazing...in the city, tall buildings, open terrain, in the forest and between cars!
City: 3 to 3.5km
Buildings: They work over 86 floors!!! I have tested them in the Empire State Building! The structure is very impressive! They would work in every big mall, hotel and school!
Open terrain: 4 to 5km
In the wilderness and forest: 3 to 4km
Between 2 cars: 2.5km to 3km (the range be longer if 3 radios were used)
In every condition they shine! Rain, extreme humidity, sand, dirt have no effect on the DTR radios. They audio is very loud and clear when their is high noise or no noise at all! I know what the worst conditions are for the radios, they have been their also! Before them I owned 3 Motorola HT1000 UHF 4Watts public safety radios they were getting to old, they batteries didn't last more than 5 to 6 hours. They range was not very good...static was a big problem! In some places I was on the same frequency as the security or maintenance... Now with my 3 1Watt DTR two-way radios have no problem and the ended costing less that other professional equipment. The last thing is the battery it last up to 16 hours, when we talk a lot!
