How it works

LCD1200-GSM+4G amplifier consists of three main components – indoor and outdoor antennas and LCD1200-GSM+4G booster box. The installation kit also includes two cables – 20m and 5m – for joining each antenna to the booster box, and everything necessary for the mounting. The outdoor antenna is fixed on the roof in order to catch any existing signal which is later sent over a cable to the LCD1200-GSM+4G amplifier. The booster box improves the signal and sends it over another cable to the indoor antenna which broadcasts the refined signal around your house or office. In this way GSM LTE Booster LCD1200-GSM+4G provides you with an improved signal across the area.

Easy set up!

I knew that to set the unit up correctly required patience and time. Completely installed it within an hour. Now I have 4g and most times full bars. I found this booster to perform exactly as advertised.

Dear Benjamin, Thank you for the feedback, we greatly appreciate it. Kind regards, Support team.

Fixed my problem

Previously I had spotty 0 or 1 bars. I had to stand in specific places to initiate a call. With the amplifier I has 3-4 bars. Calls are pretty clear. I’m able to get reliable 4g service.

Dear Masahiro, we appreciate your review. Thanks and regards, Support team.

Worked as promised!

We bought one for mother-in-law, who has a metal roof and therefore no mobile signal. This did the trick. It doesn't give us as strong signal as we get outside, but it's does what it is supposed to do.

Dear Austin, we are glad that you are pleased with the amplifier. Kind regards, Support team.

Case Studies

Catherine Bodill, Manchester

This booster is an ideal way out for us!

My husband and I liked to spend time in our countryside house very much. Unfortunately, EE mobile signal there is far from perfect. The problem was that the number of provider’s masts was insufficient and didn’t ensure good reception around the zone. Therefore we started to look for a solution. The booster offered by team perfectly coped with this problem and ensured stable connection in our house.

Ross Gayden, Aberdeen


I would like to say that I am fully satisfied with the level of O2 mobile signal in my office currently thanks to the signal booster purchased at Previously the employees at my office constantly complained about O2 signal issues, but now all the problems have disappeared. Mobile coverage around the office is perfect, and I receive no more complaints.

Nathan Mars, Plymouth

Fully ready for the set-up. provides effective mobile phone signal boosters in full set. I received my order just in three days and didn’t spend any time on buying additional equipment for installation as everything was already included in the kit. Moreover, the company has sent me a user’s manual with instructions and guidelines for successful installation.
