How it works

Let’s have a look at the main working principle of LCD250-4G-D mobile signal booster. First, the outside antenna catches the existing signal and passes it over a cable to the LCD250-4G-D booster box whose function is to improve the poor signal. Next the refined signal travels over another cable to the inside antenna and is also caught by the whip antenna, both working to disseminate the strengthened signal around your house or office providing you with a usable indoor cell reception. The full set contains a manual with detailed installation instructions which will help you to set up the device on your own. In any case, don’t hesitate to contact us if needed before you proceed.

Big improvement in cell service

I have a detached building with a metal roof which I use for entertaining. But there were no cell service inside. I installed this booster in less than an hour and I not only have cell service, but internet connection as well. Bottom line - it's pricey enough, but if you have decent to good signal outside, but crappy signal inside, then this will really help!

Dear Richard, we are glad to know you are enjoying the amplifier! Best regards, Support team.

This is my second booster. I have one at home, it’s a triband model. As for LCD250-4G-D, I installed it in the office to improve poor 4G/LTE. The device works well. The internet connection at work has become much better.

Dear Rob, that you for the feedback. We would be glad to see you at our store again. Kindest regards, Support team.

Case Studies

Sandy Everard, Welshpool

Excellent signal guaranteed!

EE’s tariff plan I was subscribed to was perfect for me and I never wanted to change that and look for another contract with another operator, even though signal issues at my apartment were driving me crazy most of the time. But when I heard of signal boosters and specifically, it has changed my life for the better and helped me receive strong signal without any issues and interruptions.

James Golden, Warrington

Easy to connect, great to use!

Assembling a signal repeater is really very easy and can be done in just a few steps – and I have experienced that myself. The only things I had to do was to place the outer antenna outside my window, then connect it to the booster box, plug the second antenna in, and then plug all the system inside a power socket – and that’s all! I am genuinely really impressed by how easy it turned out to be.

Victoria Trew, Galway
