There are many intercoms on the market that claim to be 10km intercoms, 50km intercoms, 100km, 500km or even 1000km intercoms, but when you actually use them you will find that the data may have to be cut in half.As we all know, high power walkie talkies can make the communication distance longer, which can reach 5-15 KM or even further in the suburbs. So,what is the reason for the shortening of the intercom communication distance?

The reasons for this can be found in the following points:

1. The antenna used is not in line with the frequency range of the machine or the antenna is not screwed in place, resulting in a short communication distance.

2. The antenna is broken; improper behavior in the process of use leads to physical shortening.

3. Loose or mis-matched antenna or antenna head.

4. When the battery power is low, it will cause the transmission power of the machine to drop, causing the communication distance to be short.

5. Between the floors of large shopping malls, it is easy to weaken due to factors such as walls and obstacles.

6. Urban buildings and large equipment have a great influence on the communication distance.
