How it works

The repeater consists of various parts. The full set which we provide includes NS-300GW dualband booster box, an indoor antenna, an outdoor antenna with 10m cable, and a power supply. In order to improve weak signal you need to catch it with the outdoor antenna, boost it with NS-300GW repeater, transmit it to the indoor antenna and finally catch an improved signal with your cellular phone. Taking into account the stages that the signal goes through before getting to you in an improved condition you should remember that it’s better to locate the outdoor antenna in places with the strongest existing signal from the provider’s masts. Together with this booster model we also offer other dualband solutions for larger, e.g. our best-seller in France NS500 GW dualband amplifier for large areas up to 500m2.

Customer Reviews

Works great!!!

I was skeptical at first that this would do any good inside my house. However, after installing the booster, I’ve been very happy with the results. For the first time ever, I was able to make a phone call while being in my living room, instead of going out to the yard.

Dear Seng, thank you for a detailed review. Kind regards, Support team.

This product really works!

I’ve struggled for years with spotty mobile service in my house. Went from not being able to use my phone to clear reception. Now have great signal strength. I would recommend this to friends.

Dear Ekamresh, thank you for your review! Keep enjoying the booster. Best regards, Support team.

So happy I bought it.

I live in a valley, and had two bars of cell service at best. The installation takes some time. Now it works fantastically. All the components look of good quality. I now have full bars in the house.

Dear Karl, we are glad to know you are enjoying the amplifier! Kind regards, Support team.

Wish we had installed it earlier!

To say that we are impressed would be an understatement. It did the job perfectly! The installation instructions were very clear. The process went fairly quickly and smoothly.

Dear Soren, Thank you for your feedback, it means a lot to us! Best regards, Support team.

Beyond impressed

Recently we bought a house by the lake. It’s located far from a cell tower. We might get 1 to 2 bar signal. Since we installed the booster, we keep a 3 to 4 signal, and the internet speed has improved.

Dear Edward, good to know that we could help you. Kindest regards, Support team.

Quality Product

I bought this booster a month ago, and I am satisfied with the purchase. Connecting up the three-part set was rather simple. I recommend trying temporary placement for a while if it is possible to do so, just so you can make sure the signal is the best one you can receive. Everything you likely need is included in the kit. The outside antenna is to be mounted up high and outdoors, but it does not require special skills.Their customer service is remarkable. The instructions that come with the booster are straightforward and clear.

Dear Kevin, Thank you for the feedback, it is very important for us. Kind regards, Support team.

Awesome and simple

I bought a vacation home in the country with poor cell signal outside the house and virtually non-existent inside. After reading reviews I decided to try the NS-300GW. The unit arrived on time. Aside from having to drill holes myself to fix the outdoor antenna, overall very easy to install and understand. Remember that the unit takes your outside signal and brings it inside. The quality of the inside reception depends on how good you direct the outdoor antenna. I determined the location of my nearest cell tower and pointed the antenna in that direction. After installation I saw immediate results. My phone was holding 2 bars 4g lte. My mobile unit jumped to 4 signal bars sometimes 3. This device is rather expensive but worth the money.

Dear Bryant, Thank you for a detailed review, we greatly appreciate it. Best regards, Support team.

This device is awesome.

We needed a device to improve our cell signal strength at our workplace. Our cell signal was weak, calls would drop and we had to find the place where our phones would work. Our company purchased the Nikrans NS-300GW system to solve this problem. I read the directions and had it installed in less than one hour. All of the team noticed an immediate improvement in the cell phone signal strength and reception. Moreover, no one had a dropped call.This system significantly improved our ability to function as a company in a remote area. Would recommend this product for areas where cell service is sketchy!

Dear Samuel, We’re pleased that you are satisfied with the results. Kindest regards, Support team.

A low-maintenance device

I always love it when I don’t have to buy any extra details, wires or antennas, because online stores tend to not mention such things. But this one worked out perfectly, and I never have to adjust anything when it works. Though upon installation you have to find a really good place for the outdoor antenna could nicely catch the signal. I had to change the position of mine twice.

Hi Jasper, we’re glad that you love our store, policies, and products! Sincerely, Support team

Very easy to handle

I’m really not good with tech devices, but this signal booster is very easy to handle even for someone like me. I don’t need any specific knowledge or any tools to maintain it. Great, simple, and works very well.

Hi, Hammad! Our repeaters are easy to use indeed, and that was our main purpose. We’re glad you loved it! Best regards, Support team.

Very glad I purchased it

NS-300GW turned out to be an ideal option for me. I’ve been having signal issues since I moved into my own house in the countryside, and it was driving me crazy, but now everything is great, both calls and internet!

Hi Nabiha! We’re very glad that our product helped you sort out all of your signal troubles so well. Best regards, Support team.

This really worked

I live in a very rural area far enough from the cell tower. I could hear callers but they couldn't hear me. This signal booster eliminated my problem. Except for getting the antenna on the roof, the installation process was easy and the cables were long enough to meet my needs. Overall, I’m quite satisfied.

Hi Jo, thank you for your feedback, it means a lot to us! Best regards, Support team

Case Studies

Andrew Meyer, Cannock

Pretty easy in installation.

Putting together a cell phone signal repeater is easy and even fun. I had absolutely no problems during the process, even though my technical knowledge is slightly above zero and I could easily mistake one plugging port for another. But I didn’t, thanks to the detailed instructions. The process has just a few simple steps, and the most difficult question I faced was “where to place the booster”.

Angel Da Costa, Leicester

Thanks for technical support!

Mobile-signal-boosters.co.uk website was really helpful, and, I guess, I wouldn’t be able to write and post this review without the help of their technical support. They helped me to choose my perfect and affordable booster model according to my situation and answered all of my questions, even though at first I was sure I chatted with a bot. And eventually I ended up with my Lycamobile signal problem being solved, just as it was promised!

Arthur Thornburn, Newcastle upon Tyne

My signal used to be extremely poor.

It’s a commonly known fact that people usually have weak phone signal in the forests, but I never drew my attention to things like these, until I bought a piece of land with a small cabin on it. Later I found out that there was barely any BT Mobile signal there. The reasons behind it were actually painfully simple: BT Mobile cell phone tower was pretty far away and there was a lot of trees blocking the signal.
