NS-GD-L-Boats Overview

Nikrans NS-GD-L-Boats is a unique dualband booster model that improves mobile voice connection on boats and yachts of large size.

Coverage area

Its antenna allows boosting a signal in the area up to 30 000 ft2 (3000 m2), so it can be efficiently used on yachts with few decks and levels. However, it is possible to connect up to 4 inside antennas which would be efficient for yachts with several rooms, for example. The number of users who can take advantage of the amplified signal is unlimited.

Signal types supported

The booster functions at GSM 900 and DCS 1800 MHz frequencies, which makes it compatible with all mobile providers in Europe, Asia, Oceania, and Africa. This model is mainly designed to improve GSM/DCS signals and provide stable mobile connection (voice calls). However, on condition that providers in the region use 900MHz band for 3G or/and 1800MHz band for LTE 4G, the NS-GD-L-Boats will improve mobile Internet on your boat as well.

Benefits and features

The dualband booster for boat Nikrans NS-GD-L-Boats has some benefits such as:

  • Shut-off option for turning off the device in cases of extensive input signal or incorrect setup.
  • Automatic Level Control (ALC) regulates incoming signal level on the basis of individual signal reception conditions.
  • Manual Gain Control(MGC) is used to manually control an incoming signal gain for getting the best signal reception.
  • Automatic Gain Control(AGC) is necessary for adjusting signal automatically and controlling booster functioning.
  • Two power supplies (12V and 220V) are shipped with the booster for your convenience.

NS-GD-L-Boats boat booster meets the international safety standards.

Kit contents and setup

The GSM signal booster for boats NS-GD-L-Boats is simple to use and install. The marine repeater kit includes an omnidirectional outside antenna which can receive signal in 360° degrees around the ship from several providers’ antennas on the coastline at the distance up to 40 km. The design of the device is so well-developed that even users with no technical background will install it on their own. The installation is very quick and won’t take more than 15-20 min. As soon as you switch on the amplifier, the mobile signal starts improving automatically.

Operating rules

Nikrans amplifier for boat doesn’t emit radiation when functioning. We recommend using a lightning protector to prevent your booster from breaking down. Other safety measures are described in the user manual.

Our professional support team is always ready to answer all your questions.

NS-GD-L-Boats Customer Stories

NS-GD-Boats-L is an excellent marine cellular booster for our needs.
NS-GD-Boats-L is an excellent marine cellular booster for our needs.

Tom Hedges (Ireland, Waterford)

Everybody wants to have a great internet connection and high levels of GSM signal, even when being at the sea. Especially when being at the sea, I would say, because people who travel by sea pretty often want to stay connected with their families or simply get bored on long trips when there’s nothing around but water. And due to poor coverage because of being far from the shore, a lot of signal issues happen.

The best marine amplifier that I have ever had!

Mark Schranz (Malta, Valletta )

This marine amplifier doesn’t consume much energy and space of the boat, it’s really compact, looks nice and fits in pretty well. It’s energy-saving, extremely low-maintenance, easy to put together and use, and, overall, is a good buy that we are very happy with. Someday we will probably upgrade to buying a booster for internet frequencies as well.

Guys, if you like sailing as much as I do, then you can really understand the problems that I used to have some time ago before I found this web site. Being in the sea, have you ever faced with weak mobile connection? I am sure that such a problem is rather common for those who have yachts and who like spending free time sailing.
