Please ensure the outdoor and indoor antenna have distance of 20 meters at least, with a wall between and not at the same horizontal line(outdoor antenna can be one floor higher than the repeater and indoor antenna).Indoor antenna and repeater better to be minimum 4 meters far away from nearby windows and doors. To use this product to enlarge your signal, the outdoor signal shall be as good as possible. The product will not work well if our outdoor signal is not good or bad. In case the indoor signal is always very low while outdoor signal is very good, the repeater can work well. If the indoor signal is sometimes full sometimes not at all before installing,  this environment is not suitable to install the repeater.     Reasons to Purchase Cell Phone Repeater. 1) The Signal Repeater provides the well-organized service that is why after installation of the system the quality of the connection will be really great.2) Signal Repeater require no additional wires being attached to your cell thus allowing you to use your cell without any extra troublesome accessories, in other worlds, no physical connection to your cell .3) They are practical, beautiful and easy to install.

All s that are under the coverage and are suitable for the frequency of your repeater can use the amplified signals.5) Signal Repeater is able to cover different coverage: from small to large. In this case you can decide which of our repeater is suitable for your office or supermarket.6) Repeater works at full duplex. It means that they not only receive the weak signal from the mobile base station and then divert to mobile after amplifier. They also receive the signal from your mobile and then send it to the mobile base station.7) Our equipment is completely safe. Mobile repeaters do not produce any radiation. The repeater makes the signal stronger in places with poor signal coverage such as: 1) Underground areas: basements, parking lots, tunnels; 2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;3) Places distant from the BTS like private houses. Note: One indoor antenna only use for about 300 square meters. If you want to make all use of 1000 square meters which the host supports, you need to add more indoor antennas (about 3-4) and power divider / splitter.  Welcome your inquiry if you need.
