1. What does a mobile phone signal booster include? How does it work? Can I
use the signal booster when the outdoor signal has 0 bar?
1) A signal booster kit mainly includes a signal amplifier ,an outdoor
antenna(with a 10 meters coaxial cable ), and an internal antenna(with a 5
meters coaxial cable) etc.
2) Outdoor antenna receives the signal from the base station to transmit to
the repeater, the signal is boosted around the place via the indoor antenna to
improve the call; It is suitable for transmitting the voice and data of mobile
phone, tablet PC, or the Internet.

not help to generate any signal. For example, if your outside signal has 0 bar,
it can not work or bring you any signal.
2. My outside signal only has 1 bar, the booster can bring me signal?
Yes, it can. According to this situation, you need a higher dB gain booster

antenna. You can contact our customer service to get related information.

network operator has its own technology and frequency. The signal booster can
only work well when it is suitable for your network frequency, otherwise it

need make sure:

antenna signal do not interfere with each other.
Please try to change the direction of outdoor antenna.
8. What square meters signal will the booster cover？

11. What is the difference of different outdoor antennas?
For area with good outdoor signal strength, you will need the standard Omni
directional antenna which does not need to be pointed at the local mast asit
receives and broadcasts the signal in all directions, such as the omni tube
antenna ,the fiber glass antenna, etc. If the outdoor signal is weak, you need

The right angle antenna is the plug and play antenna, and it does not have
cable, but convenient to install, suitable for the area around 100 square

2000 square meters, especially suitable for the large area such as factory,
