Detailed Product Description
hot sale signal repeater 1800mhz signal booster mobile signal amplifier with wholesale price 

 A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals.  The repeater device features easy installation & operation, build-in indoor antenna and no interference.  It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones.  A mobile phone repeater is ideal for house, home, office use.



How Booster/Repeater Works?

Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.




Introduction To Mobile Phone Signal Repeater 

1. Enhance Mobile Phone  Signal Strength

2. Improve  Communication  Quality

3. Reduce Cellphone  Radiation

4. Protract  Cellular Battery Life

5. Economic Building Cost

        6. Easy Operation

        7. Easy Installation

        8. Build-in Power Supply


Steps that describe the work of Repeater.


1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to the installed Repeater.

3) The Repeater accepts the low signal and improves it.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.

1) The product does not include accessories of cable, connectors and antennas that you need to buy extra. It only provide power adaptor and instruction book.







Installation Approaches

  1. Fix up outdoor antenna reception on housetop and point to signal tower.
  2. Connect outdoor antenna to “outdoor” port in repeater machine through cable.
  3. Connect indoor antenna(s) to “indoor” port in repeater machine through cable also.
  4. Plug power adaptor into AC power socket and finish installation.

Technique Supporting

  1. If still no signal receipt after activated repeater, please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70DBM.
  2. If can not call out, please adjust the direction of outdoor antenna.
  3. If strength is not steady, please check if outdoor & indoor antennas are too close. 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).
  4. 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 phone thus allowing you to use your cell phone without any extra troublesome accessories, in other worlds, no physical connection to your cell phone.

3) They are practical, beautiful and easy to install. You will not need to hire anybody to provide the installation of the equipment. You will be able to install it by yourself using only the manual list attached to your repeater.

4) The system can be used by multiple phones. All phones 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 phone after amplifier. They also receive the signal from your mobile phone 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.




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.

Why chose us.jpgAbout us.jpgCE.jpg




Q: Can you add a second wall mount indoor panel antenna as indoor to the signal booster kit?

A: Yes, extra indoor antennas are available. You will need splitter and more cable to connect the extra antennas to the signal booster.



Q: Is there any max long of wire from the signal booster to the outside antenna? 

A: Cable is used in the systems to connect the antennas to the amplifiers. Unfortunately, cables are not perfectly efficient and will lose some signal in transit, depending on the type, quality, and length of the cable. Ultra Low Loss LMR-400 cable loses 2 dB of signal over 50 feet while standard RG6 coaxial cable (like you use for cable television) loses 5 dB of signal over the same distance. When possible, you should use the shortest and highest quality cable available to ensure that a minimal amount of signal is lost from the antennas to the amplifier. Generally speaking, try to use cable max 25 meter(82 feet).


Q: I have a camper will the signal booster work there ? 

A: As long as you can get a good outside signal and install the outside antenna properly, make sure the outside antenna and well isolated with inside antenna, yes, the signal booster will work in a camper.



Q: When I am home I have absolutely no service. it says extended. could the signal booster possibly work for me?

A: If you have service outside of your house such as on the street in front or back of your house then it will work if the booster is placed such that nothing is blocking it from the nearest tower for your service provider. If you have no service at all, even outside of your house, the booster will not work for you.  In order to boost a signal it needs at least (a weak) signal to begin with. you need some type of signal outside your home to be able to boost it. If you have a weak signal outside and non-existent inside, the booster will work well and give you a good signal inside home no matter what construction material the house is.




Q: Can I use a 75 ohm cable to connect the signal booster with the antennas? 

A: Yes, the signal booster can use the 75 ohm cable, but the attenuation is big.  We recommend 50 ohm cable for the signal booster for less gain loss and a better signal output.
