How it works

Each 4-Band Signal Booster Nikrans NS-300-Smart is composed of a mobile signal booster box, an inside antenna that is to be connected to a booster with a coaxial cable and an outside antenna that should be connected to a device with a cable as well. The standard length of the cables is 5 and 10 meters respectively. If such a length is not enough for you given the specificity of your house, you can always order an additional cable of the appropriate length. But please, bear in mind, that if the utilized cable is longer than it is needed, it may have a negative impact on the performance of your mobile phone signal repeater. Don’t use the cables that are not approved by the manufacture of the device.

Powerful penta band booster

To start with, I’d like to tell you that this is my second booster bought here. The first booster I purchased here was for my house located in the mountains, the signal there was very weak, and now it’s good. This penta band booster I decided to order for my parents, who face the same problem. Initially they wanted a booster just for bettering GSM, but as my family spend time there as well, and we all use mobile internet, I’ve chosen NS-300-Smart.

Dear Ophelia, thank you for leaving the feedback. Keep on enjoying it! Kindest regards, Support team.

Perfect for my cafe

This booster was installed in a small café that I own, and now we purchased some fancy backgrounds for Instagram pictures, and our clients love the café even more! They can post their pictures right there.

Dear Angelica, we’re really happy that your café is doing so well now with the stable internet signal! Best regards, Support team.

Excellent signal

Ever since I bought the Nikrans NS-300-Smart, every room of my house has high-quality signal. Even the bathroom and the basement. My kids are very happy, since the basement has always been their playroom.

Hello Zachariah! We’re happy that you and your family enjoy the good signal now! Best regards, Support team.

Case Studies

Tyler Dillard, London

Our booster was delivered intact and in full set.

I would advise to choose devices offered by Mobile-signal-boosters.co.uk as this company provides the full kit and you won’t have to purchase anything additionally. What is more, the shipping is very fast, for example, I received my order just in three days. As soon as I unpacked it I started the installation as I had everything necessary delivered in the set.

Sean Sawin, Chelmsford

Huge mobile signal issues in my hotel.

Let me share my experience in using a signal booster. I purchased a mobile signal repeater at Mobile-signal-boosters.co.uk to improve Asda poor signal in my hotel. The main reasons for Asda signal problems (and sometimes for other operators) were thick concrete walls of the building which didn’t allow the signal to reach people inside. I realized that I may start losing clients because of these inconveniences and decided to install a repeater.

Linton Hiett, Ryde

In our case a signal amplifier was the one and only solution.

When you have to deal with mobile signal issues, you start looking for the reasons why your signal is imperfect. In my case, I couldn’t blame the operators as the problems were caused by the construction of the building itself. No matter how strong the signal was, it couldn’t penetrate through thick and massive walls. The only solution to this difficult situation was to install a signal booster, what I actually did.
