The outdoor Yagi antenna receives the downlink signal from the base station, and the mini power repeater amplifies the signal. Indoor repeater antennas broadcast the signal to cover the user's home or office. The uplink signal of the mobile phone is transmitted to the repeater through the relay antenna, and after the uplink is amplified by low noise, it is transmitted to the base station through the donor terminal.
The repeater works with two antennas, one is the internal antenna that communicates with the data card of the mobile phone or laptop, and the other is the external antenna that communicates with the cell tower.
When the indoor antenna receives the signal from your mobile phone or data card, the booster amplifies the signal and transmits it to the outdoor antenna through the cable, and then to the cell tower. So the better the outdoor signal, the more coverage the indoor antenna can create.
Micro repeaters are mainly used in office buildings, shopping malls, large underground parking lots, exhibition centers, workshops, etc. Note: This duct can only enhance 2G/3G/4G call signal and cannot extend 3G/4G internet signal.
Relying on the unique advantages of compact structure, light weight, convenient installation, little interference to the network, reliability and stability, the miniature repeater has been widely used.
Installation Notes:
1. The outdoor antenna should be installed in an open area outdoors where the signal is good and stable. When installing, it should be installed horizontally, pointing to the place with good signal or towards the base station, and the small vertical bar is vertical to the ground.
2. Use the outdoor antenna feeder to connect the amplifier's outdoor interface OUTDOOR，pay attention to tighten the interface.
3. Install the indoor antenna in the room where the signal needs to be enhanced, try to choose a higher place (the height is greater than 2 meters), and install it downward.
Installation Notes:
1. The distance between the outdoor antenna and the indoor host is more than 7 meters to prevent self-excitation.
2. The connector cable needs to be tightened to reduce the attenuation during signal transmission.
3. The outdoor Yagi antenna/panel antenna needs to be aligned with the base station when installing.
