How it works

1800 MHz Mobile Phone Repeater Nikrans LCD-400D has a high-tech and very pleasant design, moreover, it is very compact which means that it can be installed practically in every room even without being noticed. It has an extended coverage area. It gives you an opportunity to use this booster for houses, office buildings, shops and hotels with several floors. If the structure of the building where you need to improve mobile signal is too complex, you can use special splitters and additional indoor antennas (a standard set includes one antenna that should be used inside and one antenna that should be installed outdoors to catch at least poor signal of your carrier) which will guarantee better coverage in the rooms that are rather remote from the place where LCD-400D booster box is located.

Case Studies

Thomas Marbach, Kirriemuir

Perfect choice for my O2 signal problems!

The assembling process of my LCD booster is the easiest device-related assembling process you could ever face. I easily did at by myself in a few very easy steps and it’s impossible to do anything wrong! I am very satisfied with the result and the fact that they put clear and detailed instructions into every package so that everyone can understand how to put the signal booster together.
John Brink, Chichester

Extremely happy with my signal booster!

Despite the fact that I have reasons to like my operator, I was stuck in the house with poor and interrupting signal, while I needed internet badly because I was looking for a job and doing freelance assignments at the time. Signal issues made my working process a lot harder and annoyed me really much, so I decided to change that and do something about the signal. My family said I should try to buy a signal booster.

Sheldon Birchall, Doncaster

The booster arrived quicly after I passed the order.

I didn’t have to wait too long for my order to arrive. Just as it was promised on Mobile-signal-boosters.co.uk’ website, it was delivered to me very quickly – in three days. I wasn’t expecting it this early (and I totally forgot about the tracking number while being busy with other things), so it was a really pleasant surprise. All the parts that were needed to amplify my poor signal were already in the package.
