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.

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!

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.

Despite all my fears and lack of experience, I installed the booster fully on my own! The instructions provided in the manual are very useful.
Stable connection. I had an issue with an outdoor antenna but I am still proud of myself.
