How to effectively improve the communication distance of the walkie-talkie?

Dojammer 2022-04-15

When using the walkie-talkie for communication, the communication distance of the walkie-talkie is a problem we feel distressed. Is there any way to increase the communication distance of the walkie-talkie? These points may help you:

Improving the antenna system is one way to improve radio performance. Consider how a radio signal propagates: it travels in a straight line and may be blocked by buildings, hills, trees, or any other natural or man-made obstacle. To optimize and maximize range, the antenna must be as high as possible. This improves the line-of-sight of the walkie-talkie and produces a better, stronger signal. With an effective antenna system, sometimes all the user has to do is move to a higher position to maintain a strong communication connection.

Use repeaters

If changing or adjusting the antenna doesn't fix the problem, then it may be time to install a repeater. The repeater receives and retransmits the signal from the radio with increased power.

Use U-band or V-band frequencies?

VHF wavelengths are longer, allowing signals to travel longer distances, but also making them less efficient in highly blocked areas. UHF has a shorter wavelength, which makes it more effective at penetrating concrete, metal, wood, and other obstacles than VHF. You can choose according to your environment.

Make sure the battery is fully charged

Low battery strength can affect the strength of the radio signal. Walkie talkie batteries drain slower than cell phone batteries due to their lower power consumption, but they do lose strength over time. Check your two-way radio batteries regularly to make sure they are fresh.
