Kit contents and setup

All our mobile signal boosters are sold in full kits. No additional accessories are required for their functioning. This booster set includes two antennas (one ceiling indoor antenna and one outdoor antenna), one booster box that will strengthen the signal, cables and mountings.

We also provide a possibility to customize an order. For example, you can order a longer coaxial cable if it is required.

Operating rules

We recommend being extremely attentive and careful while installing all the elements of this booster. It’s vital to place and connect all the components just as it is described in the instructions. By the way, together with your booster, you will get a detailed manual prepared by our experts.

For example, your outdoor and indoor antennas should be placed at a vertical distance of at least 10 meters. And the cables used to connect them to a booster box shouldn’t be too long if you do not want the improved signal to lose its power when it is being transmitted.

On our website, you can find tons of interesting information about our devices, including cases written by our customers.

I know that many people buy amplifiers for their flats and houses but we decided to purchase such a device for our office as it was absolutely impossible to work with the quality of Vodafone mobile internet that we used to have!

Bailey Nicholls (Plymouth, UK)

We live in a nice town on the seashore. We moved to this place only 2 years ago and we think that it is an ideal place for our family. But it used to have one huge disadvantage. Our flat is situated in such a location where our Vodafone mobile signal was absolutely unstable.

George Pfeiffer (Exeter, UK)

Let’s be honest, the quality of my Vodafone mobile signal at home always left much to desire. I just was too lazy to do anything with it. I was absolutely satisfied with the rates and the quality of the signal that I had everywhere and my own house was an exception.

Purchased Nikrans BD-400FG

Personally I do not like the design. However, that’s not a key parameter for a booster and I still bought it. As for functioning, no questions at all.

Purchased Nikrans BD-400FG

This booster has changed our understanding of a good connection. Working in the office building located far away from the nearest cell tower, we were used to suffering *LOL*. Now we see how stable our connection in the office could be. Thank you!

F (Portugal)
Verified Buyer
Purchased Nikrans BD-400FG

The price for a booster with such capacities is really cool. It has a wide coverage area that is sufficient for our private house (and the house is not small) and it works with 2 signals simultaneously.

The website contains a lot of useful information. That’s pleasant that the company takes care of its customers

J (Denmark)
