-70dBm
-90dBm B-50KR User Guide 9 STEP 2. Install the Outside Antenna The outside antenna must be mounted outside the building with the strongest cell signals. Mount the outside antenna as high as possible facing towards the desired location of the cell tower and facing the opposite direction of the expected location of the inside antenna. Outside / Inside Antenna Separation For the best performance, a minimum of 50 ft. distance between outside antenna and inside antenna is recommended. The bigger the separation distance from the antenna, the higher the coverage provided by the booster. However the smaller the separation distance, the lower the coverage provided by the booster. 10 B-50KR User Guide STEP 2. Install the Outside Antenna Install the outside antenna in the location to receive the strongest signal according to the instructions of STEP2. Make sure the outside antenna is installed facing towards the cell tower. 2 1 3 B-50KR User Guide 11 STEP 3. Run the Outside Antenna Cable When mounting the outside antenna to the outside wall of your building, the easiest way is to run the cable on the outside of the wall and attach it to the exterior of your oflce & building. Then drill a hole through the wall which will allow the cable to appear on the inside of the building. To avoid any potential harm or damage, make sure that there are no electrical outlets, sewer water pipes, or electrical wiring in the wall before drilling. Note TV cables already being used for other purposes can not be shared with the cell booster during installation. After drilling the required hole, run the cable through and seal it. In some instances, it may be possible to run the cable up into the fascia of the attic overhang. In this circumstance, the cable will be accessible in the attic further routing.

Flashing Red during 30 mins, then Solid Red. Outside antenna and Inside antenna are not isolated enough from each other. So the Signal Booster is shutdown at this frequency. Uplink Signal coming from the outside antenna to Base Station is too strong and may cause troubles to carriers network, so the Signal Booster stops service at this frequency. Signal from BTS station is too weak. Outside antenna and Inside antenna is not isolated enough from each other. The Signal Booster works properly. Change the position of Outside and Inside antennas. Make sure the Outside antenna is not facing towards your own roof or at the inside antenna as this will cause isolation issue and the signal booster will stop amplifying signals at this frequency. Change the position of Outside and Inside antennas. Make sure the Outside antenna is not facing towards your own roof or at the inside antenna as this will cause isolation issue and the signal booster will stop amplifying signals at this frequency. Change the position of Outside antenna to receive stronger signal from Base Station. Change the position of Outside and Inside antennas. Make sure the Outside antenna is not facing towards your own roof or at the inside antenna as this will cause isolation issue and the signal booster will not be able to amplify signals at maximum power.

AGC (Auto Gain Control) The Signal Booster checks isolation between inside and outside antennas once a day. AGC sets up downlink and uplink gain value automatically depending on the input power level. ASD (Auto Shutdown) There are two cases when ASD works. 1) Outside antenna and Inside antenna are not isolated enough from each other. So in order to protect the Signal Booster from damage, it will automatically shutdown at this frequency. 2) Uplink Signal coming from the outside antenna to Base Station is too strong and may cause troubles to carriers network, so the Signal Booster will shutdown at this frequency.
