Retevis RT81 Long Range DMR Handheld Radio (UHF/VHF optional) with Six-Way Charger Kit

Retevis RT81 is a long range DMR handheld radio that has two versions available: UHF or VHF optional. UHF two way radios are ideal for city use, and VHF 2-way radios are perfect for outdoor use. This 6-pack radio bundle also includes a convenient six-way charger for efficient charging of multiple radios or batteries at the same time and a programming cable for easily setting functions.

This 6-pack with 6-way chargers is ideal for small, centrally managed groups. It is equipped with a six-way charger capable of charging up to six radios at the same time.
The six chargers are designed to facilitate team management and to avoid individual mistakes. When we centralize the management of the team's equipment, we can better realize the team cooperation and activities.

Main Features of Retevis RT81 DMR Handheld Radio High Power

The maximum power can reach 10W, while the high-gain antenna can provide stronger signal transmission and penetration ability. This allows you to have higher-quality communication.

Digital Communication

The sound quality of digital radio can be better compared to analog walkie-talkie to keep loud and clear and keep good sound quality until the end of the coverage area.

Digital Encryption

Secure communications are an essential requirement, especially for public safety applications. The RT81 is equipped with 10-bit key data encryption; RT81 DMR two way radio prevents eavesdropping and avoids interference to ensure secure communication.

Sturdy Body

In the security process, it often happens that the walkie-talkie falls down by running. Therefore, there are certain requirements for the fall resistance of the walkie talkie. A robust shell with stronger protection against falls and earthquakes is more durable.

Private/Group Call

For security, it is necessary to communicate. The walkie-talkie supports individual and group calls with ID by setting the frequency, time slot, etc. to meet complex communication requirements.

Six Advantages of DMR

DMR technology offers six benefits, including doubling the capacity of existing licensed channels, backward compatibility with legacy systems, longer battery life, and increased energy efficiency that improves working efficiency, extends walkie talkie life, and reduces equipment replacement costs.

Digital radios offer many advantages, including: better voice quality; wider coverage; longer battery life and greater safety; in addition, they are often compatible with analog radios

All Call/Group Call
Allows you to talk to other people at the same time, even if they are not on the same channel

2200mAh rechargeable battery

long run times are no problem; 15 hours in analog mode; 25 hours in digital mode. Out-of-the-box; 16 channels pre-programmed with CTCSS/DCS to minimize unnecessary transmissions.

FAQ on Retevis RT81 Long Range DMR Handheld Radio

Question 1: What is the range of Retevis RT81?

Answer 1: RT81 long range DMR radio can reach 3 miles under ideal conditions. But the actual range may be affected by factors like the terrain, obstacles, weather, etc.

Question 2: Is the encryption of RT81 compatible with other radios?

Answer 2: Besides RT81 DMR radio itself, RT81's encryption can also be compatible with the encryption of the old version RT50 Waterproof DMR Two Way Radio (10 keys).

Question 3: Can RT81 work with RT29?

Answer 3: Yes, RT81 DMR digital 2-way radio can work with the RT29 long range analog two way radio in the analog mode. Since both RT81 and RT29 have VHF or UHF options, at first, you should make sure they have the same band, VHF or UHF. If you want the RT81 to work with the RT29, please ensure they have the same frequency and CTCSS/DCS in the analog mode.

Question 4: What's the benefit of the Dual Time Slot?

Answer 4: RT81 handheld DMR radio supports the Dual Time Slot, which allows two signals to share the same channel at the same time. One on Time Slot 1 and one on Time Slot 2. They do not interfere with each other and improve frequency usage efficiency, which is especially important in areas with busy communications.
