1. What kind of range should be expected ?

The range of radio transmission is highly affected by the environment. Theoretically speaking, the line-of-sight range of Radacat can reach up to 30km or more in wide open areas. The more open the space, the greater the range will be.

Generally, terrains like plains, desert, and open beach can allow ranges up to 6km. Transmission range is expected to reach up to 3km in crowded areas like cities, mountains or forest. However, under some circumstances, such as where there are buildings or hills between senders and receivers, or if there is electromagnetic interference, the transmission range will likely only reach up to hundreds or even dozens of meters.

Placement of your device also affects the range. A device hung in a high place in the open air will provide better range. For example, clipping the Radacat C1on top of your backpack or to its strap over your shoulder will provide a better range than keeping it in your pocket or in the car.

Generally speaking, text messages can be transmitted several times farther than voice messages. When voice messages fail to deliver, sending text messages is advised. All product specs are subject to text measurement.
