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.

Arrived quickly

The purchase from the store has arrived really quickly. I expected it to be much longer and was prepared to wait for at least a week, because no delivery has ever worked fast in my region. But what a pleasant surprise it was! But that’s not the only good thing about the repeater, it also works great. My signal is really good now all over the house, and I don’t have to worry about missing important calls anymore.

Hello Jakob, and thank you for your review. We’re always happy to help, and we work with the best delivery services in the world. Best regards, Support team.

Impressive result

In the area where I live data has always been iffy, and our operator couldn’t do anything about it. We couldn’t even think about streaming something without waiting for it to buffer first. Since we installed this booster, life has been much easier. We have a big house and we share it with another family, so we share a booster as well, and it supports all the devices that we all use at the same time. The only thing: we had to order an additional antenna for indoors as one was not really enough.

Hello Marek! Our boosters can support an unlimited number of devices! We’re glad that it helps you and the people you live with. Best regards, Support team.

Good product

Our house always had one bar of cell phone signal, both inside and out. Even though we have three cell towers near us, within a couple of miles each, it didn’t really help much. Sometimes people who called us on the phone couldn’t hear anything and had to hang up. And sometimes we couldn’t hear them. Anyways, I bought this booster, and it actually worked. It was a little hard for me to find a place where to put it so that the signal would distribute all around the house. Eventually I put the outer antenna on the rafter in the attic, and it helped. The antenna isn’t even outside, but it’s already working really well.

Hi Muhamed, thank you for your review! It’s good to know that the booster you bought has worked out for you. Best regards, Support team.

Highly recommend this model

It works throughout our entire house, with no problems at all. Solves all of our mobile reception problems flawlessly. It’s absolutely worth the money! The delivery of this repeater was also really fast and we did not expect it to be like that, so it was a surprise in a good way. It arrived at our house in less than two business days (or just two days, since it was midweek). The team has provided us perfect solutions, support, and recommended this repeater model to us, and now we’re very happy with it. We can talk on the phone for hours in any room and watch movies on streaming platforms with zero buffering time. Excellent job!

Hello Frederick, our team was really happy to help you and we’re glad that our product has helped you so much. Best regards, Support team.

This model is amazing for huge houses

I come from a big family that occupies a large house, and I often had issues with signal boosters being not powerful enough for the entire building. I purchased several models from different brands before, but ended up returning them, because they never lived up to their standards. But after I got this booster, I’ve had no problems whatsoever. It really amplifies the signal throughout the entire working range it’s supposed to have, which includes two floors of my house, its garage and its basement. Every family member can use their devices anywhere, and their signal reception doesn’t suffer at all. Me and my son conducted experiments in every room, and came to conclusion that the amplified signal is equally good in any of them. So, get this model for big houses, if you want a really good and reliable one!

Hello Albi, we’re glad that this repeater model makes your huge family so happy! Our customers are our top priority. Best regards, Support team.

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.
