Signal types supported

This 3G booster functions at 3G 2100 MHz frequency. This frequency is used by all European and most mobile providers worldwide for 3G data transmission only, and it does not work with GSM phone calls and voice connection.

Benefits and features

Its major features are:

  • LCD display. The screen displays most important information including setup tips, error messages and solutions and system data.
  • Sleep mode. The device goes into sleep model in non active periods, which helps save energy.
  • Automatic operating control. The device has ACG function for adjusting gain depending on the outside signal. Also, ALC function for signal level regulation and auto shut-off in cases of self-excitation.
  • Multiple phone support. The 3g mini booster is able to support 100+ mobile connections simultaneously within its coverage area.
  • CE and RoHS certifications. The booster has no harmful impact on its users during amplification.

Kit contents and setup

We ship each repeater in a full kit together with the necessary items for installation of the whole system. 3G antenna booster Nikrans LCD-150 3G kit includes indoor and outdoor antennas, two cables, mountings, and a manual.

The installation is really simple and takes about 15-20 minutes. You don’t have to bear additional expenses on technicians as you will manage everything on your own. It’s only necessary to connect the booster with antennas with cables and then power the device on. Just in 5-7 seconds the 3G signal will reach 5 bars on your mobile phone.

The device is proved to be safe for adults and kids staying in the zone with amplified signal. It’s even more helpful as together with the better signal it brings a lower level of mobile phone emissions. In the area with weak or absent mobile signal radiation emissions from mobile devices exceed their normal value as mobile phones automatically start searching for a stronger signal. After being installed a Mini repeater will help to improve the signal and decrease extensive emissions.

Operating rules

This 3G LCD mobile signal repeater is what will help you to be always connected to 3G internet. To use it with maximum efficiency, please follow the steps of the manual while installing the device.

LCD-3503G Customer Stories

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

Marcel Fimpa (Congo, Boundji)

One of these boosters, LCD-3503G, seemed to be the most appropriate variant as it was not expensive and, as it was written on the website, it was designed to improve 3G signal. And yes, in reality, it is doing its work very well. Now I have excellent mobile internet at home.

I could boost signal for cell phone Djezzy! Finally!

Sami Natouri (Algeria, Laghouat)

When I started having Djezzy signal issues, I didn’t want to sit and do nothing and just wait if the problem would go away by itself. I need a good internet quality all day and at night as well because of the job I have, and I need to be online all the time to be able to receive important messages. Djezzy poor signal wasn’t included in my plans at all.

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

Lastri Pranata (Indonesia, Sengkang)

Of course, lack of mobile internet at home was very irritating for me, as I need to stay online 24/7. It is normal nowadays. But due to Telkomsel poor signal I didn’t have an opportunity to stay in touch with my friends. Of course, I could call them or send SMS. But who does this today? Mobile online apps are much more convenient for communication for young people.

LCD-3503G Customer Reviews*

Purchased Nikrans LCD-3503G

It is such a small cute device! I even didn’t know that such a little box could be able to boost the signal. But in any case, I am happy that finally I’ve found this solution. It’s better late than never.

Very stable 3G signal.

Purchased Nikrans LCD-350 3G

Without a doubt MyAmplifiers is a great customer-oriented company who really try to help. The Live Chat is fantastic to help answer questions on which amplifier to buy. Having said that I would just advise purchasers two moments: 1- To get good indoor coverage you need more power. For the 400m2 coverage LCD 350 is really not enough but unfortunately the price goes up steeply for more powerful models. 2 The cable provided to connect the external antenna to the amplifier box is very thick and heavy. This leaves you with a problem in how to pass through a wall or window and makes simple installation difficult.

Great customer service, help and support. Good prices. Fast delivery. To get the power you need you have to buy a more powerful and more expensive amplifier. Installation is not quite easy as implied.

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.

The price-quality ratio is excellent.

After I managed to install a booster, everything is fine. Even though so many people say that it was easy for them to install a booster, for me it was a challenging task.

Hi, guys! Many thanks for this cool booster that has saved my working process. I am a freelancer, so a good internet connection is a must for me. The device is very compact and it is an important advantage for me.

The repeater fully fulfills its functions, it perfectly improves the 3G signal and even when strong winds are blowing and it is raining heavily, the signal is okay, though earlier bad weather used to spoil our connection.

A very nice booster and a very nice price, exactly what we needed for our summer cottage. I think that we will buy the same model for our grandparents’ house.

This booster is suitable for students, couples or families who live in apartments or small private houses. Even when the weather is awful, strong winds do not affect the quality of the 3G signal. The device has a very stylish and modern design.

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..:)

A (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.
