Retevis RT81 radio, long distance walkie talkie

Long-range walkie-talkie is an excellent choice for hiking, camping, hunting and other outdoor activities, as well as professionals in construction, security and other industries. We have already talked about the dual time slot technology of RT81 last time, you can directly check the link the bottom of the article. Today, Sunny brings you the explanation of RT81 long-distance conversation.

Factors affecting the usable range of the two way radio

First, we need to know that the maximum range of a radio is tested under ideal conditions set by the manufacturer. Under ideal conditions, where most environmental factors are eliminated, we assume that the signal travels only through the air.

The maximum range of a walkie-talkie depends on a variety of factors, two of the most important being:

Output power and Antenna type/size.

Output power

Most US consumer walkie-talkies fall under one of two FCC-regulated radio services: FRS (Family Radio Service) or GMRS (General Mobile Radio Service). FRS have fixed antennas and use a maximum of 2 watts of power. Handheld GMRS radios are limited to 5 watts, which can provide greater range in some situations.

Antenna type/size

In fact, the longer the antenna, the greater the transmission range of the walkie-talkie will be, so the easier it will be for the walkie-talkie to pick up communication signals over greater distances.

Influencing factors in reality

Factors such as the weather, the geometry of the landscape around you, the types of obstacles in the landscape, noise from other radio signals, and your altitude all play a role.

RT81 long-distance communication

RT81 Dual Time Slot High Power IP67 UHF DMR Radio. It adopts detachable antenna and optional high and low power design. High power has longer talking range. High and low power options can be used flexibly, allowing you to choose the appropriate power in different situations. If you want to get a longer communication distance, you can choose a long antenna to increase the power, so that you can have a better communication effect.
