Coverage area

The Nikrans NS-300-Smart booster can cover up to 300 m² (3,200 ft²) that makes it an ideal amplifying system for small to middle-sized premises, e.g. offices, spacious apartments, private houses, basement dwellings, shops, and so on.

Signal types supported

The NS-300-Smart booster amplifies mobile signals at 800, 900, 1800, 2100 and 2600 MHz. Traditional GSM bands for European and Asian countries are 900 and 1800 MHz. They are also used as 4G frequencies, together with the 800 and 2600 MHz which are largely operated by many carriers. The frequency band of 2100 MHz can also be utilized for 4G transmission, although nowadays many providers offer 5G Internet in this band. The 5G connection is also supported by the frequencies of 800 and 1800 MHz. The booster is capable of strengthening 3G internet in the 900 MHz frequency band where this signal is still transmitted. However, it is important to keep in mind that the same type of connection can be broadcast in various frequency bands depending on the country and operator.

FREE Lightning Surge Protector (€30 value)

Savings of 30€ and additional protection as a gift

Each set of NS-300-Smart comes with a free lightning surge protector! This is a great opportunity, as lightning protection is crucial for the efficient operation of the mobile signal booster.

All customers, but particularly those who reside in areas with frequent thunderstorms, should consider installing a lightning surge protector.

The system installation is simple and accessible to anyone without technical knowledge or qualifications. It takes about 20 minutes to complete. As soon as you plug in the booster the signal will improve just in 5-7 seconds.

The mobile signal booster has a user-friendly interface. It requires no additional maintenance or manual adjustments. Simply follow the operating guidelines and safety measures provided in the manual.

Thank you for an excellent discount. We were looking for a booster for our hotel for quite a long time period. Actually, we liked this model from the very beginning but the price was the main factor that prevented us from buying it just at once. But then we saw that MyAmplifiers introduced a very pleasant special offer and we managed to buy this repeater with a discount that allowed us to save 450 EUR. That’s cool!

The booster itself fully met our expectations.

The more we use this repeater, the less I can understand how we managed to live without it (it was a torture). Thanks for this excellent device at a very pleasant price.

The delivery took just a couple of days and I didn’t expect to get it so quickly.

That’s so cool that MyAmplifiers offers discounts on their popular models. Before buying this repeater I had been trying to make up my mind for a couple of months. This booster absolutely met all my requirements but I thought the price was rather high. But then I saw a discount and placed an order immediately.

This booster is an ideal variant for our small office. It’s very powerful and reasonably priced.

Easy installation, stable functioning without interruptions, high capacities. The order arrived a little bit later that we’d expected (maybe because of a holiday season).

We bought the Nikrans MA booster three weeks ago. We sincerely tried to get used to intermittent gsm mobile reception in the house, but in the end we lost patience and ordered this dualband booster that suits for all our networks. Being a non tech I set up the device within 1.5 hours approximately. In the result, 1-2 bars I had before improved for 4-5 bars. That is perfectly enough for making calls.

Amplifies coverage area of available cell service. Mobile reception is much better in every apartment of the house. Compatibility with all mobile networks of the country.

A couple of years ago I bought a booster for my house but after my company moved to a new office building we faced serious problems with our mobile connection. So, I decided to suggest buying a booster. We are absolutely satisfied with NS-300-Smart. It perfectly works even when a lot of phones are using the improved signal simultaneously.

Purchased Nikrans NS-300-Smart

As far as I understand now, the problems with a mobile connection can be noticed in every corner of the world, and even the most luxury places can’t be considered to be an exception. I realized it after I moved to Monaco. According to my friend, who is an expert in all these things related to mobile networks, in my case, the problems with low mobile signals are a consequence of using some construction materials for building my house. Nobody can guarantee you that when you move to a new house, you won’t face some similar issues. The only thing that I could make was to buy a booster. On this website, I found a couple of variants that had sufficient coverage, and then the sales manager helped me to make my final choice given the frequency bands that are used by my mobile operator. Just in 10 days, I could already enjoy my stable connection. Thanks!

I work as an administrator of a sports center. Every day at least a hundred people visit us. But the problem was that in our building smartphones couldn’t catch a signal. It means that when our clients came for training, their relatives, friends, and co-workers couldn’t reach them. Of course, we were preoccupied with this situation. Nevertheless, we have found a solution! It is the best device for us.
