Many customers mentioned the distance range of walkie-talkie can not accept such long distances as advertisements.

Then, how to extend the walkie-talkie’s distance range?

To extend the walkie-talkie's distance range, consider upgrading to a higher-power radio with a longer-range capability.
Radio communication is ultrashort wave communication, and distance range influenced by buildings, hills, trees, and electromagnetic fields, such as blocking and interference, affect the actual distance and quality.

Walkie talkie Equipment Factor:

1.Power:

The bigger of the output power, the greater the emission signal coverage, and the farther the distance range.
A 0.5-watt system might require users to be within 100 yards (91.4 m) of each other, while a 5-watt system might extend that distance up to 10 miles (16 km). The maximum communication range is generally determined under perfect conditions, meaning that there are no forms of obstruction between the two walkie-talkies. When buildings are in the way, the range of indoor communications is typically reduced dramatically because of the various elements of building construction. Consider the terrain and surroundings when determining the effective communication range of your walkie-talkie system.

So if you need long distance walkie talkie, please consider the high-power two-way radio. (Also, comply with your local wireless communication rules)

If you don't have any license, please choose the license-free band.

2. Receiving Sensitivity:

The higher walkie talkie receiving sensitivity, the further the distance range .

3. Antenna:

The higher the gain, the greater the power, and the further the distance range. As we all know, the antenna is very important for walkie-talkies and repeaters.

If you are going to build a repeater, do your best to mount the antenna at a higher place. As I know, Lots of repeaters mounted on the top of the hills or building roofs.

4. Frequency:

UHF (ultra high frequency) and VHF (Very High Frequency)

UHF band walkie talkies are widely used in urban, and VHF band two-way radios are widely used in outdoor.

Environmental factor :

Environmental factors mainly include path, the density of trees, electromagnetic interference environment, buildings, weather and terrain difference, etc.

Other factors:

1. Low battery :

When low battery, call quality will become worse ,even worse,there will be noise, influence the normal calls.

2. The antenna matching:

Frequency and inconsistent machine frequency antenna, antenna impedance mismatch, will seriously affect the distance.

3. Base station:

When you have a base station and repeater nearby, the walkie-talkie’s distance range will be amazing!

A base station, another name for is repeater. It will receive the signal and retransmit it at the same time. So if your handheld radios or mobile radios with the range can't reach the distance you want, you may consider ordering a repeater.

Retevis released some repeaters for business use.

For example, Retevis R1 Analog mode repeater.
