Nikrans LCD-GDW-Boats is a universal marine phone signal repeater which boosts weak GSM / 2G, 3G signals as well as poor 4G connection. The multifunctional character of the device is due to three operational frequencies GSM 900 MHz for calls and 2G Internet, DCS 1800 MHz for calls and 4G LTE Internet and WCDMA 2100 MHz for 3G Internet. As you can guess, thanks to simultaneous support of the mentioned frequency rates the booster is compatible with a wide range of operators. Another advantage of the amplifier is that it is able to boost signal for an unlimited number of users simultaneously. One inside antenna which is included in the standard set up kit can boost signal in boats and yachts on the area up to 5000 ft2 (500 m2). In case this coverage is not sufficient for you, there is a possibility to install up to 4 inside antennas in order to enlarge the coverage area. An omnidirectional outside antenna is able to catch signals in different directions 360° degrees around the boat at a distance up to 40 km.

The main functions of the triband boat amplifier include:

  • LCD display. The device has three displays – one for each working frequency. These displays provide information about the set up process, system errors, signal level, etc.
  • Sleep mode. Sleep mode is activated when you don’t use the device. This function helps to save energy when you don’t need the amplifier. As soon as your mobile device starts looking for an improved signal the booster begins to work again.
  • The installation kit contains two power supplies (12V and 220V), which means that you will be able to choose the one that best corresponds to your needs.
  • Auto gain and signal control. The device makes it possible for the system to change the operational characteristics depending on the signal Make your life easier and more comfortable regardless of your location!

How it works

LCD-GDW-Boats is absolutely an amazing solution to deal with poor mobile signal while sailing. Its powerful external antenna can catch the signal transmitted by your provider’s station situated even in 40 kilometers in any direction (so, no aiming of your antenna is required). This booster can cover up to 5000 ft2 (500 m2) indoor boat area, nevertheless, if you have a huge ship with a number of rooms you can always order additional antennas to send amplified signal to mobile devices. What is more, for your convenience we will send you two power supplies (12V and 220V) with your order. But if something extra (like additional antennas or longer cables to connect components of your booster) is needed, it is possible to purchase them.

Not bad

It’s good. Improves signal at a distance between the boat repeater antenna and the providers` masts up to 30 km. Works with all operators.

Great when you are offshore

I have been using the repeater for a few months and have noticed no drawbacks yet. For me it is very important that the work of marine mobile amplifiers does not affect the operation of navigation devices, the quality of ship's radio navigation communications, and is absolutely safe for human health and the environment. Moreover, I feel safer and protected with this device as I’m always in touch when I’m offshore.

Dear Markus, thank you for the feedback. We are happy to know that you are satisfied with the purchase. Best regards, Support team.

Effective and compact

Let me say a few words about this wonderful device. That may sound like praise but it’s worth every penny! LCD-GDW-Boats is the booster I have been using for half a year and I’m totally in love with it. The model is very compact but it’s effective and reliable. Before buying it, I decided to contact the support team to be sure about the model I had chosen and they told me that this triband booster would be okay for my yacht. The model ensures stable voice connection and uninterrupted 3g, when I’m offshore. I’m enjoying every minute of using my mobile device now, as the coverage is perfect and without any signal issues.

Dear Max, thank you for the review. Keep on enjoying it! Kindest regards, Support team.

Case Studies

Abraham Thorby, Portsmouth

Talk Talk signal issues on my boat.

Undoubtedly, Talk Talk is one of the most popular mobile networks. Personally I like it for fast internet and reliable phone calls. But not a single operator is ensured against signal problems, especially the ones which occur in the sea. Talk Talk network is not an exception. Fortunately, has an effective solution to Talk Talk signal problems, which is called a marine signal booster.

Boris Chryssanthis, Torquay

At last a reliable coverage!

The results of using a marine signal booster purchased at were amazing! There are no more poor phone calls and slow text messages when in the sea. The internet connection is perfect as well. My clients always have full bars and as a result their phones get discharged less frequently. People can easily enjoy reliable coverage and sail further from coastline. The device is well worth the investment.

Stanley Keigher, Seaham

The result is wow!

I would never have thought that the installation of the marine signal booster is such an easy task. My friend helped me to set up the device and we managed to fulfill the installation in half an hour. We mounted the external and the internal antennas, connected them to the signal booster box and turned the device on. It started to boost the signal automatically in a few seconds.
