This booster has amazing coverage. I was impressed! That’s exactly what we needed for our shopping mall.
Full kit! No additional elements were required. Rather tricky installation due to the fact that this booster has 3 indoor antennas.

MyAmplifiers, thank you for your support services. My boss asked me to find a repeater for our office building and I really didn’t know what to do. But thanks to the help of the support managers, I’ve done a good choice. The device works without any interruptions.

The coverage area is the main benefit for us. We were ready to order two or three boosters at once but this model solved our problem. Three indoor antennas! Thanks! I do not know whether there are any other models with three antennas that ensure good coverage in all corners of the buildings.

Good device! Highly recommended! The coverage is really surprising. We didn’t expect that we would find one device to satisfy all our needs. We were ready to buy a couple of boosters to install them on different floors so that the signal would reach all the rooms.
The booster has a very wide coverage area and it is compatible with GSM, 3G and 4G networks simultaneously.

The booster is quite expensive. But have you seen its coverage? Wow!!! We asked the sales manager more than once whether that’s not a mistake. Even when the device arrived we didn’t believe that it would be really so powerful. But yes, that’s true. We are impressed.

Purchased Nikrans BD-18K-Voice, 3G & 4G PRO
The installation was a real challenge! The amplifier has 3 indoor antennas and all of them have cables that are used to connect them to a booster box. We were a little bit confused with all these items. But finally we managed to install it!
Good price Challenging installation
