C20L-5B-EU Five Bands Signal Repeater for Europe

Product Features

*Large-size OLED screen to display device’s operating parameters,

*Real time isolation detection function. Device will auto detect and alarm when at insufficient isolation,

*Idle stand-by function, uplink will auto enter stand-by mode while no active users in the coverage area, to decrease interference to the base station,

*MGC manual gain control function, with 1dB step to attenuate gain among the range of 25dB

*ALC auto level control function to ensure stable signal,

*Light weight, compact design, low consumption and easy installation methods,

*MTBF can be up to 100,000 hours.

C20L-5B-EU is a highly intelligent five bands wide band signal repeater, specially designed for Europe market by Amplitec R&D team. Amplitec R&D team adopts EDA digital simulation technology, elaborately select and repeatedly check the components and circuit match of it. All core components are purchased from original manufacturing factories which are famous worldwide. All original designs are to ensure the perfect technical specification and performance. In addition, C20L-5B-EU adopts Amplitec’s patent technique, isolation detection and digital ALC, which makes the device’s performance and functions are both much better than similar products.

C20L-5B-EU, with five bands of EGSM900, DCS/LTE1800,WCDMA2100,LTE800,LTE2600, can amplify 2G 3G 4G and 5G wireless network of all mobile operators in Europe. It carries with features like novel design, easy installation and engineering methods, and 20dBm downlink output power to cover an area of up to 500 square meters, which makes it a perfect option to enlarge and enhance the signal coverage of villa, office, elevator and basement, etc.
