Many customers concerned about the walkie talkie communication range. But do you know how to increase walkie talkie communication range effectively? We’ve sorted out solutions as below, let’s study together!
Solutions to increase walkie talkie communication range:
1. Increase the transmit power
Almost all of the walkie-talkie has a high, medium and low three-shift transmit power adjustable. For the walkie talkie, the transmit power is generally selected between 0.5 ~ 5W; For car radio it’s between 10W ~ 40W. when there’s significantly noise during communication, then switch to a higher transmit power, you can improve the communication quality and extend the communication distance. Transmission power doubled, walkie talkie communication range can be extended to 1.4 times of original distance. However, the aimless and random increase in transmitter power,will increase the power consumption, electromagnetic radiation and increased interference and other negative effects.
2. Increase the receiver sensitivity
The receiving sensitivity of the radio has a great influence on the communication distance. For the user, we can adjust the radio’s squelch figure level, to get a better receiver sensitivity. We can also switch to a high-gain antenna to increase the radio receiver sensitivity. For example, for a walkie talkie antenna, the telescopic gain is highest; r / 4 whip and spring screw followed. Generally, the longer the antenna, the ability to receive weak signals is also stronger. When changing antennas, pay attention we need choose the same frequency band antenna (different frequency band antenna is not compatible).
3. Try to choose an open place to call
Communication range given by suppliers,normally is the theoretical communication distance, which is tested in open areas, in the absence of barriers. The concrete buildings in the city, will absorb radio waves seriously. Therefore, for the indoor use of walkie-talkie, we should try to choose window position, for outdoor use, we need avoid the surrounding of tall buildings,trees block, big advertising board.
4. Put the antenna position as high as possible
The increase of the antenna height is very effective for expanding the communication distance. One testing show that, two walkie talkies that have around 4km when using in city environment, if one is take to a the top of a mountain which is 100km far, they can still communicate!It’s amazing!So we should try to find a higher place for communication,if you can talk on 2nd floor, then no 1st floor.
5. the use of urban canyons: This is very important, our city is building-intensive, it is difficult to find a real opportunity to spread the line of sight, so we have to make good use of the existing environment. The so-called urban canyon refers to both sides of the building-intensive, tall, but the middle road is straight, wide road then the effect of communication is generally better. Therefore, we propose that if you are ready to communicate while driving, please enter the wide road and then start.
6.night walkie talkie communication range is better than daytime communication effect.
G.fixed-point communication is better than mobile communication effect .
While, refer to communication range, Retevis RT1 is real 10W radio, it’s communication range is the best in Retevis analog radio.
Acquire good habits when using walkie talkie
regular check if the walkie talkie battery is sufficient, if the antenna is connected firmly, whether the telescopic antenna is fully pulled out, these factors have a direct impact on the radio transmitter power and receiver sensitivity, thus affecting the communication distance.
