Retevis P1 is DMR handheld Repeater with Single Frequency. P1 Range Extender Single Frequency Repeater extends the range of your digital handheld two way radios by 20-50% depending on the height of altitude of your location.

What's the actual range of a handheld radio?

In urban high-rise environments, the range of handhelds is very modest: vertically, you might be able to clear anywhere from 5 to 20 floors in a building; horizontally, 2-5 city blocks if you're standing on the street.

In suburban areas, direct handheld-to-handheld communications are usually feasible within 1 to 2 miles, depending on housing density and terrain. It can be considerably less if there are hills or office buildings in the way.

Finally, in sparsely-populated rural regions, a range of 3-4 miles is usually possible - although again, it can be less if there are hills or dense forests in the way.

In exceptional circumstances, such as transmitting from a hill or a tall building overlooking a rural valley, you can get as much as 20-40 miles.

The theoretical range of Handheld radios to range?

The upper limit on the range of handhelds is largely a matter of physics: for most part, radio waves propagate in straight lines and are absorbed by stuff that's in the way. The usual distance to the horizon from the vantage point of a six foot tall person is around 3 miles. Past that point, things begin to slide "below" the horizon and end up in the largely impenetrable radio shadow of the planet we all walk on.

Single frequency handheld repeater is the most effective and feasible improve range solution?

A single frequency handheld repeater system is a simple and convenient solution for overcoming communication interruptions in various scenarios. This system utilizes a simplified repeater scheme, combining the functionality of a handheld radio with an antenna and power supply.

One of the key advantages of a single frequency repeater is its portability. Being a handheld device, it can be easily carried and used in different locations without the need for complex installations. This makes it an ideal choice for individuals or teams who frequently encounter communication interruptions while working in remote areas or challenging environments.

When the single frequency repeater function is activated, the radio signal can be forwarded, ensuring seamless communication between team members. In situations where there is a person in the middle of the communication chain, they can simply turn on the single frequency repeater to overcome any signal loss or degradation caused by the curvature of the earth.

By relaying the signal, the single frequency handheld repeater system effectively extends the range of communication, allowing team members to stay connected even in areas with poor signal coverage. This can be particularly beneficial for industries such as construction, event management, and outdoor activities where reliable communication is crucial for safety and coordination.

In Conclusion

A single frequency handheld repeater system provides a simple yet powerful solution for overcoming communication interruptions and extending the range of your digital handheld two-way radios. Its portability, ease of use, and ability to overcome signal limitations make it a valuable tool for individuals and teams who rely on efficient and reliable communication in their day-to-day activities.
