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.

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.
