Retevis RB91 wall-mounted digital UHF repeater has strong penetrating power, which can enhance the signal and expand the signal coverage. It has a built-in 15000mAh battery, which can achieve 7 days of standby. It can work with Retevis RB24 UHF handheld radio as a low power consumption and long-distance solution for basements, subways, tunnels and other areas with weak signals. (RB91 base station is only compatible with RB91 repeater and RB24 digital handheld radio.)
RB91 UHF repeaters can connect with multiple RB91 to achieve long-distance solution. It can also help the RB24 UHF 2 way radio break through the extreme communication distance and easily achieve long-distance calls.
Equipped with a 15000mAh battery, the base station provides a standby time of 7 days and a working time of 10 hours. This ensures that the base station can be used throughout the day without the need for frequent charging.
Retevis RB91 repeater not only supports regular AC charging but also supports solar charging, which is perfect for field settings where electrical power is non-existent or unreliable. You can charge RB91 with an external 18V, 600mA solar panel. (The solar panel is not provided.)
Please note that solar power is only for short-term emergency charging and cannot provide enough power for the long-term daily operation of the repeater. For stable and long-term use, please make sure to keep the battery fully charged via the main power supply.
The RB91 digital repeater features strong penetration and realizes ultra-long distance reception. It performs well in different scenarios, such as rescue support and subways, buildings, and tunnels.
The RB91 base station and RB24 two way radios can be connected out of the box without complex setup, which is easy to use. (RB91 base station is only compatible with RB91 repeater and RB24 digital handheld radio.)
