Signal types supported

This 5G/4G/3G booster functions at 2100 MHz frequency band. This frequency is used by all European and most mobile providers worldwide for data transmission.

Benefits and features

Using LCD-350W becomes easy and convenient due to its following characteristics:

  • LCD display. The screen shows most important information including setup tips, error messages, possible solutions and system data.
  • Sleep mode. During periods of inactivity, the device goes into sleep mode, which helps to save energy.
  • Automatic gain control. The amplifier is equipped with an AGC function that adjusts the gain of the device depending on the external signal. Also, AGC function initializes auto shut-off of the amplifier in case of self-excitation.
  • Support for multiple phones. LCD-350W is able to promote 100+ mobile connections simultaneously within its coverage area. Uninterrupted Internet access is provided on all mobile devices: smartphones, tablets, e-readers, etc.
  • Safety of use. LCD-350W has no harmful impact on its users or the environment during amplification. The harmlessness of the amplifier is confirmed by CE and RoHS international certifications.

Kit contents and setup

We deliver each repeater in a ready to use kit which includes all the necessary items for installation of the whole system. The LCD-350W package contains a booster box, indoor and outdoor antennas, two coaxial cables, mountings, and a manual. Pay attention to the possibility of customising your order by adding some extra elements to your kit.

The installation is really simple and takes about 15-20 minutes. You will not have to incur additional costs for technicians, as you will handle everything on your own. It is only necessary to mount the booster box and antennas, connect them with cables and then power the device on. Just in 5-7 seconds, all bars on your gadgets will show the powerful Internet signal.

The device is proven to be safe for adults and kids. What is more, in combination with an improved signal, the amplifier reduces the radiation level of the mobile phone and saves its charge. In an area with a weak or absent network, the radiation of mobile devices exceeds their normal value, as phones automatically start searching for a stronger signal. After installation, LCD-350W will help to improve signal quality and reduce emissions.

Operating rules

LCD-350W is what will help you to be always connected to all types of Internet connections: 5G, 4G and 3G. Before buying, check whether your operator uses the 2100 MHz frequency band in your area to provide the access to the Web. It is also necessary to follow the instructions in the manual while installing the device. It will allow you to use the repeater with maximum efficiency.

Contact our Technical Support Team to be sure about the model you choose.

LCD-350W Customer Stories

Thanks to my cool mobile signal booster I managed to boost cell phone signal MTN

Marcel Fimpa (Congo, Boundji)

Though I live in a small town in Congo, I have never had any difficulties with GSM calls that’s why when I chose a new mobile plan that included 3G mobile internet (I had previously found out that my mobile operator was transmitting 3G signal across my area), I was really surprised that MTN 3G poor signal wouldn’t give me a chance to enjoy mobile internet at home. Something went wrong and MTN signal problems were obvious. To tell the truth, I had no ideas how to deal with these MTN 3G poor coverage.

But I knew that I really needed to boost cell phone signal 3g at home as I needed to use it not only for private communication or entertainment. I needed to use it for my studies as well, for example for downloading some materials or books, as I didn’t have a computer. And when I was really desperate, my groupmate advised me to visit MyAmplifiers web site. At that time I didn’t know anything about mobile signal boosters and their capacities to boost cell phone signal. But when I entered the site I found so much information about them! I easily managed to find several boosters that are designed to solve MTN mobile signal problems in Congo.

I could boost signal for cell phone Djezzy! Finally!

Sami Natouri (Algeria, Laghouat)

So I contacted MyAmplifiers, and they helped me at a pretty low and very fascinating price. This is actually pretty cheap if you think about the fact that the signal amplifier will boost signal for cell phone of Djezzy poor coverage and that it would work for a long time. I bought the booster that the company has suggested to me because of the size of my house and the type of signal I wanted to be strong. It arrived really fast, and it works really well. I was pretty much worried about how it will turn out because of the local climate. But the manager ensured me that it doesn’t matter and the signal amplifier will work perfectly at any temperature or humidity. And it’s true: I’ve never had any issues with booster’s work, even when it’s really hot outside.

My 4G internet connection is good at any time of day (Djezzy poor signal is forgotten!) I placed the booster box in my living room, and it looks pretty small and nice and doesn’t spoil the design. Also it isn’t surrounded by a lot of ugly uncomfortable wires, so no one trips over them at night. Djezzy signal problems don’t bother me anymore and I am so very happy that I managed to successfully boost signal for cell phone. I also recommended MyAmplifiers and their 4g signal boosters to a couple of my coworkers, and they also say that they are very happy with their purchase.

It was difficult to find how to boost phone signal Telkomsel, but we did it!

Lastri Pranata (Indonesia, Sengkang)

Can you imagine? I had been suffering from Telkomsel 3G poor coverage in our house for several years and was searching how to boost phone signal. But then just one device fully changed the situation! When LCD-3503G appeared in our house, I forgot about Telkomsel signal issues practically immediately.

Due to Telkomsel signal problems I used to feel very lonely in the evenings. Moreover, my parents also were not very satisfied that we didn’t have proper 3G signal that’s why my dad decided to try to install a mobile signal booster. According to a wide range of reviews and testimonials, a great number of people from all over the world have already understood how to boost phone signal with the help of these devices. That’s why we also wanted at least to try. But when we installed LCD-3503G, there was no even a single reason to regret! This reasonably-priced device is very powerful! Now all my messages in online messengers can be sent just in a second, I don’t need to wait for hours if I want to check my email box, and I can even make video calls. Our Telkomsel 3G signal has become really strong. Thank you, MyAmplifiers, for this amazing device!

The device is very useful. We installed it in our summer cottage to have stable mobile internet. And this task is perfectly fulfilled.
We installed it in less than 15 minutes though we had never seen such boosters before. Though I like the design, I can’t understand why only one color is available.

Purchased Nikrans LCD-3503G
When we moved to a new house, we didn’t expect that we would face any issues with our Lycamobile signal but the reality differed from our expectations. Thank you, MyAmplifiers, for offering such a huge variety of boosters that everyone can find an ideal variant.
Good booster! So many models that it is difficult to choose..:)
Armenia, Verified Buyer
Purchased Nikrans LCD-3503G
When you live in a mountainous area some problems with mobile connection are quite common, however, in our case we had something extraordinary. We have practically zero signal! That’s why we decided to buy a booster. It was our last hope! And the trial was a successful one. The booster works perfectly.
Strong signal The number of payment options is rather limited, so we had some difficulties in opting for the most appropriate one.
Sweden, Verified Buyer
Purchased Nikrans LCD-3503G
A very compact device with a stylish design. I like the way it should be installed: quite easily and quickly. I do not need to purchase any accessories like extra antennas as the power of this model is sufficient for the area of my house.
Good price-quality ratio.
Norway, Verified Buyer
Purchased Nikrans LCD-3503G
Thanks. I think that this model deserves 5 stars because of its reliability and a very good price-quality ratio. Other devices are significantly too expensive and some of them are not affordable at all (at least for an average family)
Excellent website with a convenient search form. Once when I visited the website, all support managers were offline.
