Nikrans LCD1200-4G-D is advanced and newly-designed dual band indoor booster. Its major feature is simultaneous signal amplification at two different frequencies. The LCD1200-4G-D works at GSM + 4G LTE 1800MHz and 4G LTE 800MHz, which makes it suitable for 4G mobile Internet and GSM voice calls of most mobile carriers within the United Kingdom and EU.
This mobile repeater from Nikrans is recommended for large indoor areas up to 13000ft². We recommend using LCD1200-4G-D for private houses or offices, underground shops and clubs, restaurants and bars with several floors.
Thanks to its dualband working mode, the mobile repeater ensures high-speed and stable 4G mobile internet without drops on 800 and 1800MHz frequency bands. Also, the repeater model stabilizes your GSM voice communication on condition that your mobile provider supports GSM 1800MHz band.

How it works
The installation of LCD1200-4G-D as well as its less powerful version for France LCD500-4G-D mobile network antenna booster is very simple and doesn’t take much time. First of all you should find a place where the outside antenna will be able to catch the strongest existing mobile signal in your area. Mount the antenna and run the 20m cable from it into the building. Next lead the cable to the area where LCD1200-4G-D booster box is to be located. As soon as you have attached the cable to the amplifier, take the other (5m) cable and lead it to the place where you plan to mount your inside antenna. It’s better to locate the latter on the ceiling in case of high buildings. Once all the parts are connected, you can plug the amplifier in. The necessary information will be displayed on the LCD screen.

When I started communication with the team of Mobile-signal-boosters, I immediately understood that this is what we call customer oriented service. I placed the order at the website and their manager got in touch with me just a few minutes later. He clarified all the details concerning the coverage area and the working frequencies and confirmed it. The shipment was very fast and five days later I got my booster. I received my order safe and sound as described.
Appreciated Mark, thank you very much for the review. We are glad to have been useful to you. Regards, the team of Mobile-signal-boosters

The device is noiseless and almost unnoticeable. We were worried about the effect on the human body, as we placed it in the hall of the hotel where the receptionist works 24/7. However, the booster is absolutely safe as it emits no radiation, and what is more, it goes into sleep mode when there is no mobile activity detected.
Dear Mila, we are grateful for your review. Thank you for choosing our product. Best regards, support team.

It’s nice. The shipping was fast. The device and its specification fully correspond to the description provided at the official website of the company. Works well.
Dear George, thank you for the review. We would be glad to see you again. Best regards, Support team.
This amplifier helped us a lot in our village. There was no Internet reception at all, the signal was hardly caught. We have a nearby airport, and a forest around our cottage - that is the reason. I installed the booster on the facade of the building. The Internet speed is great now, and it’s applicable to any provider. The support team was very helpful, and the device itself works great.
Dear Donnie, thank you for the feedback. We are glad to know that your problems have been solved. Best regards, the team of Mobile signal boosters.

Good indoor booster
This is a very worthy repeater at this price. In my opinion, it isn’t expensive at all. I took it for my villa. There was no 4G at all, never. And now I enjoy stable connection. Thank you!
Dear Thomas, we are grateful to you for the review. Keep on enjoying it! Best regards, support team.
· Henry B. · Verified Buyer · 04-01-2023
I’m happy with it
I still can’t believe that I managed to do away with poor reception at my underground restaurant! Yes, I did it! And it was thanks to this booster. Amazing device! Practically unnoticeable but so effective.
Dear Henry, thank you for the feedback. We are glad to have been useful to you. Best regards, Support team.
· Garry Otis · Verified Buyer · 02-01-2023
I installed the booster yesterday. It works without any troubles. Amplifies weak signal around the area. Recommended!
Dear Garry, thank you for the feedback. We would be glad to see you again. Best regards, Support team.
Our team liked the booster. We use it at the office to boost GSM and 4G. The result is even better than we anticipated. We can make and receive calls with no problems. Audibility is perfect without any interference. We also enjoy high-speed 4G without any disconnections. Take it, you won't regret!
Hi Olivia, we are glad to receive your order. Thank you for choosing our product. Regards, sales team.

Not all bars
When I figured out how to connect cables, both antennas with a booster box and switched on the repeater, my phone showed only 4 bars instead of 5, but it caught the 4g signal. But when I restart the amplifier, I've already had 5 bars. Luckily, there are no mistakes after this first time.
Hi Michael! Thank you for the feedback. You are right, it may happen from time to time. We hope you enjoy the booster now. Best wishes, Support team.
· Amelie Ralphs · Verified Buyer · 10-12-2022
I really admire the working speed here. My order was processing within an hour, and I became a happy receiver of the model after 3 days which is rather fast. To be honest, someones forgot to add a manual to the kit and I had to google how to install the amplifier, but it wasn't difficult. I don't regret I purchased the booster- the 4g signal was noticeably improved.
Hi Amelie! Thank you for the review. That's great that the reception has become better. Best regards, Support team.
· George Palmer (United Kingdom) · Verified Buyer · 10-12-2020
The device is convenient to install and to use. The order included a full set ready for the installation. In addition to the mobile repeater unit itself, the kit contained an external antenna for a frequency of 800-1800 MHz, 20 meters of cable for it, an internal antenna for a frequency of 800-1800 MHz, and 5 meters of cable for it. There was a manual in the kit as well.
Dear George, thank you for the review. We would be glad to see you again. Best wishes, support team.
· Oliver Hamilton (United Kingdom) · Verified Buyer · 24-10-2020
I own an underground club, and my problem was that the quality of mobile connection inside the building was awful. So in order to make a call you had to go outside, as there was no reception inside. The booster solved this problem. Now the reception is good enough in the club. The booster has shown very good results over the past month that we’ve been using it. I have not noticed anything negative in its work, except for the price. In general, it seems a bit overpriced to me.
Dear Oliver, thank you for the feedback. We are glad to know that your problems have been solved. Regards, sales department.
· Zoe Ogden · Verified Buyer · 04-03-2020
I can't see shortages in my device. But I especially admire the coordinated teamwork your company provided to me. There are the best consultations and the quickest delivery I've ever met. Keep on doing so great!
Hi Zoe! Thank you for the feedback; it's a pleasure to read it. Best wishes, Support team.
· Jimmy Aldridge · Verified Buyer · 11-02-2020
I'm a manager of a restaurant which has recently been opened in downtown. Being surrounded by high buildings with thick walls, I found out the poor reception and started to browse the Internet. I chose the LCD-4G-D model because of the range of reception – the territory of the restaurant I work in is huge. My employees could easily install two antennas and connected cables to them. Also, we hid a booster box in utility-room and the quality of enhancing didn't suffer. I like the quality of conversations – the voice transmission is clear, communications are uninterrupted and there are no complaints from our clients. Thank you!
Dear Jemmy! Thank you for the review. It's great that signal issues were solved with our booster. Best wishes, Support team.
· Joseph Blare · Verified Buyer · 04-01-2020
That's pretty good
When I ordered this model I got it after several days which is too fast. When I unpacked the delivery box, everything was fine, all the components are in place. After unwrapping the package of a booster box, I found a little scratch in the left corner of an amplifier. Of course, the scratch hasn't influenced the basic function of the amplifier and my home signal I adorable.
Hi Joseph! Thank you for the honest feedback. Probably, it was a simple manufactory defect. We hope it doesn't impact our cooperation. Best regards, Support team.

Number 1 for a gift
I purchased this model for my brother because he once complained to me about the poor signal in his new apartment. Actually, I have the same model at my place and it noticeably increases the reception within the old building with thick walls. Frankly speaking, I had to wait for a week for this model because it's recently absent at the warehouse. But when they got it, the specialist immediately called me and delivered the booster after 3 days absolutely free!
Dear Mia, thank you for the review. We are glad to know you like our goods. Look at the other model on our website. Best wishes, Support team.
· William Hailey · Verified Buyer · 25-11-2019
My brother gave me this booster as a present. I’m very happy to have it! It improved the quality of the signal and ensured stable connection in areas where the reception was very poor.
Dear William, thank you for the review. We are glad to know that you like it! Best regards, Support team.
· Oliver Roger · Verified Buyer · 16-11-2019
Beyond my expectations
Frankly speaking, I wanted to leave a review immediately on the day I received my order, but later decided to test if for a few days. So, I have been using it for a week already. The result is just amazing! Everything works well. The quality of signal is good enough to download media files, uploads, and to make video calls. I always have full bars on my phone, although previously there was hardly one-two bars.
Dear Oliver, thank you for the feedback. We are glad to know that you are satisfied with the result. Best regards, Support team.

Simple & Effective
This dualband repeater is just what I have been looking for. I have already installed it, and have been using it for about a month. So now the time has come when I can share my experience. In my opinion, the booster will be useful for those who need to amplify poor signal be it in a rural area or in a city. Mostly this has to deal with 4G, but in case your operator uses 1800 MHz band for GSM, than you will be lucky to benefit from improved voice connection as well. I’m using it in my bar, which is a bit more than 10 000 ft2, but I think that it will be okay even for larger buildings, for clubs, cafes, restaurants, etc. So, I recommend it!
Dear Samantha, thank you for the feedback. Your opinion means much to us. Kindest regards, Support team.

Easy to install
I bought this booster last week. My husband managed to install it himself. Actually, it wasn’t a difficult task to do as the manual with instructions was included in the set as well. Moreover, the model has a LCD screen which makes the installation simple and understandable. The signal inside the building has become much better. I can see the result! Mobile internet is working very smoothly, without interruptions.
Dear Sophia, thank you for the feedback. We are glad to know that you are satisfied with the product. Kindest regards, Support team.
· Grace Thornton · Verified Buyer · 17-09-2019
Great product, great seller and great signal now! The device works well. The installation was very simple and the working principle is clear. Before the installation I hardly ever could catch 4g signal at my pub, and after it I always have at least weak but still 4g! When the weather is clear and not windy, it works with a cosmic speed, when it’s raining and too windy the quality of signal may be a little lower but, in general, it never disappears. I recommend this supplier and this booster!
Dear Grace, thank you for the feedback. Your opinion is very important for us. Best regards, Support team.
· Samuel Stevenson · Verified Buyer · 07-08-2019
For those who leave in areas with poor 4G this booster is a real salvation. I’ve been using it for a month already and during all this period I have never faced any problems with my 4G connection. The model has an Auto Level control and MCU control. This features help to detects system errors and to manage the level of signal gain. It isn’t big, it doesn’t emit radiation. The installation is understandable and the result is more than just noticeable.
Dear Samuel, thank you for the feedback. We are glad to know that you liked the product. Best regards, Support team.
One of our team put the booster together very quickly on his own. He placed the booster near the window, put the outside antenna somewhere out the window and connected them together, then plugged the inside antenna in, plugged it all into a power socket – and it was done. It was actually that easy! Anybody can do this on their own. Especially with the help of the user guide that came in the parcel.
Before my restaurant moved, we were using Tesco Mobile router and it was working well. It also had a very good price for us, and we didn’t really want to go through ending contracts and looking for another operator. It probably wouldn’t have worked anyway, since the problem was the location itself. I wanted to try something that would increase our 4G and GSM signals, and Mobile-signal-boosters website caught my attention.
There was a certain price range that we could afford, and after some searches, we found Mobile-signal-boosters store. They were exactly what we needed. Their managers helped us choose an ideal booster. Perfect for the size of our apartment, easy to put together. It fit BT Mobile frequencies, and we were assured that it would solve our signal problems very nicely.
