How to use walkie talkies outdoors

When entering mountains or dangerous terrain, a team of people should have at least two or more handheld platforms. Used for front and back teams. It's normal to lose one or two people in the jungle, and there's no way to communicate. The concept of walkie talkies does not differentiate how far they can reach. People often ask me for a 10 kilometer walkie talkie or a 5-kilometer walkie talkie. This kind of questioning method. It can only lead to you being slaughtered. Or disappointment during use.

The frequency used by walkie talkies is line of sight propagation, in other words, on Earth, it can be reached wherever the eyes can see it. I think standing at the summit of Bogda, you won't only see a distance of 10 kilometers, right. It is possible to directly communicate with the peak of Bogda using 5W power and outdoor antenna. The effect is good. This is an obvious example. This is a literacy sticker. So I have been discussing many professional terms.
