Nikrans LCD-300GD is the next generation, latest booster equipped with the most advanced wireless technology to amplify signals. This particular model is developed mainly for improving GSM at frequencies of 900 MHz and 1800 MHz simultaneously, both being the most common in the United Kingdom and the rest of the world. 900 Mhz is widely used for transmitting 3G signal as well, so this model may serve as a 3G booster. 1800 Mhz is mostly considered supplemental, but in some areas, it is the primary GSM frequency operated. Moreover, it is often used for transmitting 4G. Consequently, the dual band amplifier will work best for smartphones running on both frequencies. With a built-in LCD screen, it shows system diagnostics such as signal level, setup recommendations, error notifications, power management and ALC data. Hence, it becomes easy and effective for novice users to use this device.

Since it is an upgraded model of previous versions, it now covers areas as large as up to 3200 ft² (300 m²). Ideally speaking, this coverage is sufficient enough for providing uninterrupted connectivity in shops, restaurants, cafes, basement offices, and even big apartments.

Home Mobile Phone Booster Nikrans LCD-300GD is the most cost effective and reliable booster that you can use to improve your network coverage. Here are some additional features of it:

  • LCD display. An LCD display is helpful for both novices and experts. It improves user experience and provides several notifications about the device such as installation steps, antenna gain and more.
  • Sleep mode. When the booster detects no incoming and outgoing traffic, it automatically switches to the sleep mode.
  • Automatic signal control function. When network reception is poor, the booster automatically adjusts gain levels.
  • Compact size and light weight. This Nikrans booster is designed to be compact, stylish and lightweight, making it easy and portable to displace around.

LCD-300GD signal amplifier provides uninterrupted voice calls alongside stable GPRS and EDGE networks. The device has passed all stringent European safety tests and obtained CE and RoHS certificates that proves its 100% safety for usage. It does not emit harmful radiations.

How it works

It is recommended to use Home Mobile Phone Booster Nikrans LCD-300GD for small-sized buildings and apartments as it has a coverage area of around 300 m² (3200 ft²). In case you are interested in a cheaper model with shorter coverage, check out LCD-500GD GSM signal amplifier for Italy.

The booster has a booster box, two indoor antennas (for better rebroadcast of the enhanced signal over the premises), one outdoor antenna and necessary cables. The installation process is quite straightforward and doesn’t require any specific skills. But it is important to install it in a right way.

The best location to install an outdoor antenna is a roof (if there is no such an opportunity place it outdoors at you window). It should be aimed away from the building. The indoor ceiling antenna can be fixed, for example, on the first floor, in the basement or in the part of the building where the amplified signal rebroadcast by the whip antenna may not reach.

It actually works & Great customer service


Living in a remote area where Vodafone's cell coverage and internet services were unreliable our business was greatly affected. With no other viable cell carriers I embarked on a mission to find a solution. Extensive research led me to the 4G/3G/GSM Mobile Booster Nikrans LCD-300GD, designed for home and office spaces spanning up to 3,300 sq ft. This choice was driven by our consistent usage of cell phones and internet within an office building on our property.

The transformation brought by this booster has been astounding. With the inside antenna positioned within our office our cell phone signal underwent a significant evolution – from a solitary bar to a robust three bars. Our internet once nearly non-existent surged to impressive speeds of 15 Mbps for downloads and 11 Mbps for uploads. This is a remarkable improvement compared to our previous snail-paced connectivity, which hovered around a mere 2 Mbps for both downloads and uploads.

My satisfaction with the 4G/3G/GSM Mobile Booster Nikrans LCD-300GD knows no bounds. Installation proved to be a breeze and I wholeheartedly endorse it to anyone seeking to amplify their cell phone and data signals. Tech support is also awesome and they are very willing to assist in any way with installation or questions.

From 1 Bar to Seamless Connectivity


Setting up the 4G Booster Nikrans LCD-300GD was a breeze. I've witnessed a remarkable shift in my cellular signal strength – transitioning from a mere 1 bar with a reading of -121 dBm, largely due to our metal roof to a steady 3 bars of 4G LTE with a reading of -90 dBm after some fine-tuning. Equipped with the web mobile app I embarked on roof expeditions to gauge the signal's testimony repeating this process over three days to ensure I pinpointed the optimal installation spot. Because a friend told me that the weather affects the strength of the signal prompting multiple tests.

Be patient and meticulous in your tuning and you will probably be thrilled with the results, assuming you have some level of cell phone coverage now. A valuable lesson learned: persistence in finding the signal's sweet spot pays off. I'm so pleased I ordered another of these boosters for a friend in a fringe area similar to mine.

The transformation in signal quality is nothing short of remarkable. The 4G Booster Nikrans LCD-300GD has proven its mettle delivering uninterrupted call, swift uploads of Instagram pictures and seamless video streaming. Considering its budget-friendly cost this investment stands as one of my wisest decisions.

Unleashing Reliable Connections: Nikrans LCD-300GD 4G Booster Review

4G Booster Nikrans LCD-300GD

I must say that the Nikrans LCD-300GD 4G Booster has been a game changer for me. After struggling with poor signal and slow internet speeds for years, I finally decided to invest in this amplifier in February of this year, and I couldn't be happier with my purchase.

Installation was a breeze, and the instructions provided were clear and easy to follow. I was able to set up the outside antenna in a matter of minutes, and once I connected the indoor amplifier, I noticed an immediate improvement in signal strength.

Before the installation of this booster, I could barely get one bar of signal on my phone, and streaming videos or downloading files was a nightmare. But now, I consistently get 4 or 5 bars of signal, and I can easily stream content on multiple devices without any lag or buffering.

The LCD display on the amplifier is also a great feature, as it provides real-time information on signal strength and other important metrics. And the fact that it supports multiple frequency bands means that I can use it with any carrier in my area.

Overall, I would highly recommend the Nikrans LCD-300GD 4G Booster to anyone who is struggling with poor signal or slow internet speeds. It's a high-quality product that delivers on its promises, and it's made a huge difference in my daily life.

Case Studies

The package from Mobile-signal-boosters’ store arrived so fast that we didn’t even expect it to be at our house yet. After we opened it, I was pleasantly surprised with the careful way it all was wrapped. Every detail was there (the booster box, two antennas, power source and wires), new and intact, and the user guide clearly and simply explained the assembling process, that I had no idea what to do about.

Edwin Ploss, Merthyr Tydfil

We actually spent some time on mounting the outside antenna on the roof of our house and making it face the side that was opposite of the hill that interrupted our signal, but otherwise, the installation process was extremely fast and easy. All we had to do after that was to connect this antenna to a signal repeater where I had already plugged the inner antenna, and then plug it into the power socket.

Iain Mackintosh, Pitlochry

I find it a very memorable thing that soon after I switched my Mobile-signal-boosters booster on, the phone inside my pocket buzzed. It finally received a message, because the signal inside my cabin became stable and good. It was very unusual to see the working signal (four signal bars on my phone and more) at this place. The booster was actually working very well, amplifying this so very needed BT Mobile signal.
