The C20L series triple band repeater is a mobile signal repeater with high intelligence and excellent technical index. It is empowered with EDA digital simulation and unique 50Ω impedance matching wiring technology. Equipped with electronic devices and RF components originated from international famous brands, the repeater’s excellent technical index and performance are guaranteed even from the circuit design.
In order to provide 2G, 3G, 4G, 5G coverage solutions for different countries and regions, C20L series repeaters offer multiple choices of triple band combination from the most common frequency bands such as B1, B2, B3, B5, B7, B8, B12, B20, B28, etc. Besides its elegant appearance, compact size and easiness to install and maintain, it has an output power of 20dBm which enables the device to cover an area of 600m2 with proper installation and operation. That makes it an excellent option to solve weak signal problems for homes, offices, elevators, basements, etc
