The Nikrans LCD-300GDW is the latest triband repeater model that amplifies the mobile signal for GSM voice calls and 3G high speed Internet. One of the most useful features of this telephone signal amplifier is the LCD screen providing several options such as setup tutorial, error notes and solutions, and system information.

As for GSM voice calls, it supports two frequencies, 900 and 1800 MHz respectively. As far as 3G signal amplification is concerned, the LCD-300GDW is programmed to 2100 MHz. Moreover, if your operator's 4G network is deployed at 1800 MHz, you will automatically get your 4G signal amplified. Nikrans LCD-300GDW is capable of covering an area with a range of approximately 300 m2 (3300 ft2), making it the ultimate choice for villas, offices, schools, shopping centres, large apartments, and underground pubs.

Here are some of the most prominent features of this booster model:

  • A smart LCD display. From setup instructions to error solutions and signal levels, you get all types of important system notifications regarding the repeater.
  • Sleep mode. The device goes to sleep mode when no activity over the network is detected and turns back on as soon as you start making calls and browsing internet.
  • Auto signal control function. The system has a built-in feature of automatically adjusting the gains level as per the incoming network signal. As a result, you will not have to face the inconvenience of adjusting gains manually.
  • Certified by CE and RoHS. LCD-300GDW is a high-quality device certified for its quality and safety standards. Hence, it is 100% safe to use for humans and has no known impact on health and environment.

How it works

Given the fact that Nikrans LCD-300GDW has an LCD screen, you won’t have any difficulties with its installment and setting up. On the screen you will see useful tips and system data including errors and performance indicators.

The telephone signal booster set includes a repeater, one outdoor Yagi antenna and three indoor antennas (one whip and two ceiling) with coaxial cables. The external antenna is intended to be fixed outdoors while the other three should be fixed in different locations inside the building to ensure a uniform distribution of the enhanced signal (what is particularly helpful for houses with two floors, for example, or other outstretched locations). Each antenna has a cable to be used for its connection to the booster box. With your order you will receive cables of a standard length (20 m cable for your outdoor antenna, and 5 m and 10 m cables for your indoor ceiling antennas). Nevertheless, you can always order an extra cable of another length if needed.

It amplifies everything

It works nicely as promised. My family lives at the edge of a town in our detached house. Despite the fact that a mobile phone signal is OK outside the house but it’s impossible to speak on the phone inside. We have been suffering for almost a year when we have to find a place where we can talk without interruptions. And I saw your website by chance and read carefully about boosters. I chose the this model and we immediately ordered it. A full kit was delivered in 3 days with a booster box, two antennas with cables and my dad easily installed it. And voila! Our connection was noticeably strengthened! Moreover, the repeater is located in my room and I don’t have any health problems or sleeping trouble. And it operates absolutely quietly and softly. I recommend this model for the owners of small or big houses. Many thanks to the Team!

Dear Melanie, thank you for the feedback! We are happy you have solved your problems with our product! Kind regards, Support Team.

My customers love it

I bought this device for my coffee shop that used to have big signal issues due to its location inside the office building. Now the internet is working well, and people love to spend more time here and make more orders.

Hello Rex, good to hear that! We’re always glad to hear good news from our customers. Sincerely, Support team.

Case Studies

David Robertson, Blythe Bridge

O2 signal problems were so frustrating for me!

After I moved to my new house I was dreaming about for a while, I found out that no one warned me about O2 signal problems we have in this region. The satiation with the signal was actually pretty understandable, since there were a lot of hills around my house, and the nearest cell tower was still too far for me to get a decent signal, so was my only hope to get rid of these troubles.
Alexander Coe, Exeter

Installation is fairly simple

Even though I expected that I would have to hire a technician and pay extra money, I was able to put the delivered signal repeater together all by myself out of mere curiosity. Just as it was promised – few easy steps, a detailed user guide, nothing difficult. The only difficult thing was to mount the booster box onto the ceiling, but it was my personal choice. And still, I succeeded! And I enjoyed the process.

Helen Newsom, Hamilton

Completely satisfied with the proposed model! helped me a lot with solving my problems quickly, easily and completely. Their customer service is also excellent: their support team answered all of my questions, even if I considered these questions obvious and stupid, and gave me all the information. They also offered me the best booster model based on the information about my current situation, and I’m very grateful for their help.
