SPECS
What kind of range should beexpected?
The range of radio transmission is highly affected by the environment. Theoretically speaking, the line-of-sight range of Radacat can go up to 30km or more in extreme open area. The more open space you are at, the greater range you get.
Generally, terrains like plain, desert, open beach can allow ranges up to 6km. Transmission range is expected to go up to 3km in crowded areas like cities, mountains or forest. However, under some circumstances, such as buildings or hills exist between senders and receivers, or electromagnetic interference happens, the transmission range is expected only hundreds or even dozens of meters.
Placement of your device also affects the range. A device hung on a high place in the open air will give you a better range. For example, Clip on top of your backpack or strap on your shoulder will get a better range than keep in your pockets or in the car.
Generally speaking, text messages can be transmitted several times farther than voice. When voice messages fail to reach, sending text will be advised. All product specs are subject to text measurement.
