How it works

Nikrans BD-400FG is designed by the best engineers in such a way that will allow everyone to install the device quickly and easily, without any particular issues. The booster set includes several key elements, each of which has its unique function.

The booster box itself is the key one that is intended for amplifying the signal. The signal transmitted by the operator should be caught by the outdoor antenna while the improved signal is sent by the indoor antenna. It is important to install and to connect all the elements correctly. Otherwise, the quality of the amplified signal can be spoilt.

To facilitate the installation process for you, we’ve prepared a detailed user’s Guide that includes all the necessary step-by-step instructions. Nikrans BD-400FG is very easy to use. All the settings and adjustments are done automatically.

Awesome model

This booster is one of the best options in its category, I believe. Supports two frequencies and makes it possible for several users to take advantage of the amplified signal around the whole area. The installation isn't difficult at all and the operating process is almost unnoticeable.

Hello Andrew, thank you for the review. Looking forward to your next visit. Kindest regards, sales department.

Needed to customize my order

In general, the device is worth its money. It works smoothly with no interference. The only thing I would draw your attention to is that the cables in the standard set are a bit short. Especially the one that comes with the indoor antenna, it's only 5 m. So you'd better plan in advance, where you are going to place all the elements of the amplifying system and customize your order on their website.

Hello Diana, we are glad to receive your feedback. Thanks for choosing our product. Best regards, the team of Mobile signal boosters.

Good price

I've been looking for a simple but effective signal amplifier, when I came across this model. And I like everything about it - the quality, the functionality, and surely the price. It's much cheaper than other analogues, but at the same time, it is in no way inferior in quality. Recommended!

Hello George, we are glad to receive your feedback. Thanks for choosing our product. Regards, sales team.

Easy installation

In the beginning, I thought that it would be difficult for me to figure out how to install the device. However, I was mistaken. Everything is so easy! They sent me a manual with detailed instructions on the setup process. Then I looked through the information provided on their official website. It's called How to install a mobile repeater. And after this, I spent only 30 minutes on the installation. It works well.

Hello Edward, thank you for the review. Please, feel free to contact us at any time. Kindest regards, support team.

Nice product

I like this product. It is suitable both for improving voice connection and insufficient mobile internet. 4g and GSM network have become much stronger now. The only drawback is perhaps the design, which lacks a bit of style. But I hope that the developers will work on it in the future.

Appreciated Ilona, thanks for sharing your opinion with us. We would be glad to see you at our store again. Wishing you all the best, sales team.
