How it works

Looking at 3G Antenna Booster Nikrans LCD-3503G for the first time, it is difficult to believe that such a compact device can be so powerful and effective. This model is able to cover with the improved 3G signal an indoor zone of nearly 350 m2 (3800 ft2) which means that it can be a perfect variant for a private house, a large apartment and an office space.

Just with two antennas and one signal amplifier box LCD-3503G can send the improved signal to more than 100 cell phones if they are located within the area of its coverage.

Some pleasant news for all potential users of LCD-3503G: you do not need to buy something additional, everything needed for a proper work of this booster is already included in a standard kit.

I have good GSM at home, but poor 3g. So I bought this model to boost the internet connection and I’m satisfied with the result. I can use my mobile internet in every room of the house now.

Dear Fred, thank you for the feedback. We are glad to know that the device helped solve your problem. Kindest regards, Support team.

Case Studies

John Servini, Hucknall

Fast delivery. Top service.

Mobile-signal-boosters.co.uk’s delivery takes a very short period of time indeed, and it was very useful in my case. Lots of online stores have much longer delivery time, even if they claim it would be short, especially when it comes to delivering their products abroad. But Mobile-signal-boosters.co.uk pleasantly surprised me. Everything I needed was already inside the package, safely packed and absolutely intact, and I give them high ratings for that.

Wesley Eustis, Dewsbury

I needed to enhance my 3G.

I chose Mobile-signal-boosters.co.uk because the signal booster they offered me was perfect for all of my requirements. It was suitable for The People’s Operator frequencies, had the exact same price that I wanted, it was supposed to enhance only 3G internet signal, and it had a perfect size of the coverage zone. I’m usually pretty skeptical about online stores, but Mobile-signal-boosters.co.uk’ policies were the thing that bought me completely.

Paul Harraghy, Leeds

Our mobile signal was too weak and we needed to amplify it!

1.I live in an apartment with my two roommates. We share a 3G router together, and everything was okay for us until the renovations in the neighborhood began. The material that was used to insulate the building made our internet signal became a bit disrupted. After that, another tall apartment building was built next to our house, and this is when the signal got significantly worse. It needed to be solved ASAP.
