Nikrans NS350-GSM+4G/LTE signal amplifier is one of the latest booster models by Nikrans, a reliable brand known for providing high quality signal boosters. This specific 4G signal amplifier is designed to improve GSM voice calls and 4G internet connection at frequencies of 900 MHz and 2600 MHz or 800 MHz, respectively. If you are based in the United Kingdom, you can use this device with peace of mind as it is compatible all network providers there. Once you place an order, we will verify your LTE frequency and ship the most appropriate booster model.

The Nikrans EGSM/LTE signal amplifier is a robust and powerful signal booster designed to cover areas as large as 3700 ft2 (350m2). Therefore, you can use it in your apartments, villas, large offices or even underground premises with poor network coverage.

Some of the most unique features of Nikrans NS350-GSM+4G/LTE are:

  • Automatic Gain Control (AGC). With this feature, you do not have to manually adjust the gains level as the device automatically does that for you based on incoming signal strength.
  • Manual Gain Control (MGC). If you are a technical user and are not satisfied with the automatic gain controls, you can switch to the MGC and manually adjust gains.
  • Automatic Level Control (ALC). This is an added option not provided in previous models, that allows the device to automatically control the levels of incoming signals.
  • Shut-off function. The automatic shut-off function helps in avoiding self-oscillation and turns off the system in case of emergencies.

How it works

Although the installation of the signal amplifier Nikrans NS350-GSM+4G/LTE is very fast and simple, there are still a few things to bear in mind during the set up process. First make sure that your outside antenna is able to catch any kind of signal. While mounting, take into account the location of all obstacles on the way between the signal and the outside antenna. As far as the indoor antenna is regarded, it’s better to mount it somewhere in the center of the building because only in this case every part of the area will receive equally improved signal. If you have any questions regarding the installation or the functioning of the device look through the manual provided in the kit or feel free to contact our support team.

Pleasant surprise

I hope that I will never need to buy a second booster (I hope that my mobile operator will do something about our awful connection or at least that my NS350-GSM+4G will function for many-many years). But if I need to buy the second one, I am sure that I will order it on this website. My amplifier arrived even earlier than I could expect, it was well-packed, and there was a detailed manual in the box. So, after reading all the instructions, I installed it completely on my own. It was a pleasant surprise.

Dear Joe, Thank you for the review, we greatly appreciate it. Kind regards, Support team.

Case Studies

James Hovey, Swindon

Fully corresponds to our needs!

Even with our signal issues, it would have been very inconvenient for my company to change tariff plans and/or look for another operator that would possibly have better signal at our office. Or wouldn’t. So we needed to improve the existing signal, and, recommended by one of our employees, promised us they could easily do it in our case and help us work efficiently, using our internet and cell phones again.

Max Butterworth, Bury St Edmunds

So happy with our Giffgaff signal repeater!

My fiancé is a Giffgaff subscriber, and after she moved in with me, we started noticing that there were terrible Giffgaff signal issues at my place. I use another operator’s services, so we never noticed that before, until she had to use her internet and cell phone in my apartment full-time. Giffgaff cell towers are pretty far away from the region I live in, that’s why their signal couldn’t be caught very well.

Jodie Lade, Gloucester

Express and reliable delivery.

All our fears about the quality disappeared after we received our parcel from’s store. The delivery was very speedy indeed, and all the parts showed no signs of defects. The repeater itself and all of the details it required for working were absolutely intact, and packed nicely and safely. We also found a user instruction inside the box and were very happy with how extremely time-saving it is.
