Detailed Images


This series of hosts consists of two single-frequency hosts. Increase the cooling strip design around. The circuit adopts ALC control, so that the host meets the requirements of commercial-level indicators. The indicator light adopts the separate design, which can be used for the design of the indicator light .


The interior of the shell adopts modular design, more separate signal at all levels in the internal implementation isolation, internal by CNC machining, mainboard and shell one integrated mass.


Dual PCB board, separated by 7mm thick aluminum plate. The signals of the two main boards do not interfere with each other. Using high quality devices such as ceramic duplexers allows the host’s specifications to meet commercial-grade requirements.


Working performance is stable
Kunruo’s each mobile signal booster repeater, after full power output, if outdoor input signal to reincrease 30dB will not affect the host technical index, can ensure that the host will working best in the complex environment.


Indicator Light
Power:If the LED is lighting, means the repeater is connected to a power supply.
Signal:30% LED lighting means output power reach to 30%,60% LED lighting means output power reach to 60%.100% LED lighting means output power reach to 100%.
Work:The Work LED only lighting means the cellphone is working, otherwise the outdoor antenna is too near to indoor antenna made a radio frequency interference.
ALC: Automatic Level Control >10dB, the ALC LED is lighting.
BS:(Base Station): connect outdoor antenna.
MS:(Mobife Station): connect indoor antenna.
