Features

Chierda V25 is the next-generation repeater for extended communication range. It features 25 watt high power, long range communication, IP66 waterproof. It is designed to be compact and portable, which is easy to carry and install. With many advanced functions, it is ideal for use in large areas, such as farms, base sites.

Low temperature mode:

V25 repeater is built to perform reliably in extreme weather conditions. In cold environments, you can manually activate the low temperature mode, allowing the device to auto-heat and operate efficiently in temperatures ranging from -30°C to +60°C. When operating in warmer conditions, simply deactivate the mode to conserve energy and extend battery life.

Repeater Linking:

Allows for two V25 repeaters to link together to extend communication range.

IP66 Weatherproof:

Designed to withstand the toughest environments, V25 repeater offers complete dust and water protection, ensuring reliable performance even in the most challenging weather.

High/Low Power Selection:

V25 repeater offers 16 customizable channels and delivers a measured maximum output power of 25W. Users can flexibly switch between high and low power modes. High Power: 22–25W; Low Power: 5–8W.

Connect To Raspberry Pi:

V25 repeater can connect with a Raspberry Pi to enhance signal strength and unlock more performance.
