Nikrans NS-GSM+4G-PRO-Boat is one of the best boat amplifiers designed for boosting poor GSM and 4G mobile reception in boats and yachts. The model can be used in large marine vehicles as its coverage area is up to 26000 ft2 (2500 m2). The standard kit contains one inside antenna for improving the signal, nevertheless if you would like to extend the coverage area you can install up to 4 inside antennas.

The marine 4G antenna Nikrans NS-GSM+4G-PRO-Boat is suitable for boosting both voice connection and mobile internet. The device functions at different frequencies - GSM 900 MHz band for calls and 4G LTE 800 + 2600MHz bands for 4G mobile internet – so it can improve poor signal from different providers. What is more, if your operator supports 3G 900MHz technology, Nikrans NS-GSM+4G-PRO-Boat can be used for improving 3G data as well. It’s necessary to mention that the model has no restrictions concerning the number of simultaneous users, so it can better signal for several recipients at a time.

The main benefits of Nikrans NS-GSM+4G-PRO-Boat are:

  • Auto Level Control. Taking into account the incoming signal characteristics the system automatically regulates repeater software gain. 
  • MCU control. In case of any system errors digital booster software lets you know about it.
  • Longer Battery Life. Due to better level of mobile phone signal your cellular device will consume less power.
  • Omnidirectional Outside Antenna which is able to operate at a distance up to 40 km from the coastline in any direction around the ship.
  • Both 12V and 220V power supplies are included in the installation kit for your comfort.  

Order this unique marine booster and get satisfaction with perfect mobile connection in your boat or yacht wherever you travel.

How it works

NS-GSM+4G-PRO-Boat can ensure excellent mobile connection for an unlimited number of mobile users on your boat simultaneously. The outdoor antenna that is one of the main elements of a standard signal repeater set is omnidirectional which means that it receives mobile signal from different sides at the same time. The device is very easy in use, it has a function of automatic signal level control, so you do not need to set this parameter manually. What is more, the system is self-controlled, so it will notify you in case of network errors which will prevent improper work of the mobile signal booster.

Among other popular models, usually searched for Spanish providers, there is LCD-GD-Boats boat repeater, that will also work with all other EU networks off coast.

Poor design

Everything is good about the booster, except for its design. The device really amplifies calls and mobile internet, but its design leaves much to be desired.

Dear Peter, thank you for your feedback. Your opinion is very important for us. Best regards, sales team.

 ·  A (United Kingdom)  ·  Verified Buyer  · 

Professional device

We bought this marine booster a week ago. The installation was simple, my husband did it himself without any difficulties. We have no complaints about the work of the amplifier, as it fully corresponds to the description. Operates without any interference and disconnections.

Appreciated Abbie, thank you for leaving the feedback. We appreciate your opinion very much. Wishing you all the best, support team.

 ·  R (Ireland)  ·  Verified Buyer  · 

Improved the quality of mobile connection

The connection offshore has improved from 20% to 80% stable. The booster is easy to install, and it has significantly enhanced and stabilized mobile communications when the ship goes far from the land.

Dear Richard, we are happy to know that you are satisfied with the result. Thank you for choosing our product. Regards, the team of

 ·  L (Spain)  ·  Verified Buyer  · 

We’re enjoying it!

In my opinion, this is a very good way to improve mobile signal when you go further from the coastline. It’s a pity that the maximum distance for catching a signal from the land is about 40 km. Hope one day I’ll find a model with more advanced technical characteristics, but right now we are enjoying this one!

Appreciated Luisa, thank you very much for leaving the review. We would be glad to see you at our store again. Best regards, support team.

 ·  W (United Kingdom)  ·  Verified Buyer  · 

Justified purchase

I first thought that the price is too high for the booster, but then I came to the conclusion that it’s worth its money. I’d say that this is a professional device, which is a must for people who go offshore and suffer from poor connection. I believe that a stable signal is very important at sea, and I don’t regret buying this product.

Appreciated William, we are glad to receive your review. Keep on enjoying the stable signal when you are offshore. Wishing you all the best, the team of Mobile-signal-boosters.

 ·  S (Ireland)  ·  Verified Buyer  · 

Good marine booster

If you often travel by sea and hate to be without mobile connection offshore this is your salvation. The booster enhances the level of mobile signal and it works up to 40 km from the coastline.

Hi Stephen, thank you for the review. We are glad to know that you are pleased with the product. Kindest regards, sales team.

 ·  E (Turkey)  ·  Verified Buyer  · 

Powerful Marine Booster

I am really impressed with the work of this device. The mobile signal is stable even if I go far from the coastline. It’s really very important for me to stay connected when I’m offshore. And now I’m always calm, I’m not afraid to lose the signal any more.

Dear Ekrem, thank you for leaving feedback. We are happy to have been helpful to you. Wishing you all the best, the team of Mobile-signal-boosters

 ·  L  ·  Verified Buyer  · 

Nice one

This booster actually operates with multiple devices at once, and so far I had no issues with it no matter how many people used it simultaneously. The signal never got worse because of that. The internet and the GSM signal work equally well, the water is not the issue anymore. The weak unstable signal turns into 3 bars of signal. It seems not too much, but boats are different from the land signals, and it is a really good result.

Hi, Layan! Thank you for purchasing the booster at our store. We’re really glad that you like it and we’re grateful for the positive review. Best wishes, Support team.

 ·  T  ·  Verified Buyer  · 

All is well

The working range is pretty big for my one private boat, but I like hanging out with friends and family members on the beach, and the repeater works for all of us from the boat. Zero regrets about buying it!

Hi, Tommy! We’re very glad to hear that our booster helps your friends and family so much with amplifying the signal. Best regards, Support team.

 ·  A  ·  Verified Buyer  · 

Easy installation

When it said on the website that the installation would be really easy, I did not expect that it’s so true. I didn’t even need an instruction in the end, even though I still used it to be sure I plug everything right.

Hi, Aamir! It’s good to know that using our product is so easy ad helpful for you. Thank you for your positive review!

 ·  R  ·  Verified Buyer  · 

A very low-maintenance item

This booster doesn’t need any maintenance or tuning, because it works automatically, and it’s great. We just put it together, placed it (and a couple of extra antennas that we bought separately) in the most logical place – and it’s just there, doing its job. We don’t need any extra technicians, and our own technician doesn’t even have to do more work. Aside from that, the booster amplifies the signal quite well, and we haven’t faced any major signal blackouts since we installed it.

Hi, Rosanna! Thank you for leaving this review. We’re glad that you’re satisfied with our product and the signal quality is much better for you. Best regards, Support Team.

 ·  J  ·  Verified Buyer  · 

Expected a bit more

The coverage area is a little smaller than I expected. That’s not really the seller’s fault, I just miscalculated. So be careful when you purchase the booster yourself, and check the measurements well.

Hi, Johannes! We’re sorry that this happened. You can purchase an additional antenna for the same booster box to enlarge the working range. Best regards, Support team.

 ·  D  ·  Verified Buyer  · 

Didn’t expect it to work this good

Not only this booster has a very high work quality, it also has a huge range. I only needed two antennas for a large ship, and this saved me a lot of money in the long run, and I didn’t have to deal with too much wires.

Hi, Dorothy! It’s good to know that you’re so satisfied with the product that you bought at our store. Best regards, Support team.

Amplifies the signal very well

I work on a cruise boat, and we have installed these things recently. Now the weather or the location never influences the signal quality, and it’s amazing. The only thing that might influence it is being really far from the cell tower, but I guess the booster can’t create the signal where there’s none. So, long story short, this booster for boats does its job really well – 4G and GSM work like clockwork, especially at the living quarters and the lobby.

Hello Harry, шt’s good to know that you’re so satisfied with our product and your experience with signal is so much better now. Best regards, Support team.

 ·  Y  ·  Verified Buyer  · 

Very good

It took me only 10 minutes to install this onto my boat. It actually works with all of the operators in our area. All the passengers are delighted. No more signal loss no matter the location or weather.

Hello, Yasmeen! Thank you for the positive feedback. We’re happy that our booster works so well for you. Best regards, Support team.

 ·  R  ·  Verified Buyer  · 

Does what it’s supposed to

It’s not easy to get signal while on water, and if we do catch some of it, it’s frustratingly weak. Things changed when we bought this repeater for our boat. It seems that it really catches the weak signal wherever it can and amplifies it. So yeah, it works! Both cell phone signal and 4G internet work so much better, and everyone noticed that. Now we don’t have to worry about missing any important news from the land while we’re here.

Hello Rufus! It’s great that you have such stable signal now. Thank you very much for your positive feedback! Best regards, Support team.

 ·  R  ·  Verified Buyer  · 

Good product

I’ve bought the booster not so long ago, but I have already tested it and I can tell you that I have no complaints about the product and the supplier. I’m satisfied!

Dear Ross, thank you for leaving a review. We are happy to know that you are satisfied with the product. Kindest regards, Support team.

 ·  J  ·  Verified Buyer  · 

Good job

This is my third booster of this company. I like this supplier. Their products are of high quality and they offer good service. I bought a home booster here a few years ago, then I purchased an amplifier for my car, and finally, this time, I decided to buy a repeater for my yacht. All the boosters work without any troubles. The support team is very polite and caring, it’s a real pleasure to work with them!

Dear Jasmine, thank you for the feedback. Your opinion means much to us. Best regards, Support team.

 ·  E  ·  Verified Buyer  · 

I’m impressed

I’ve been looking for such an amplifier for so long, and finally I have found it! The supplier provided everything for the installation. The cables for antennas were included in the order as well. The indoor panel antenna had a 5 m cable and the outdoor omni antenna had a 10 m cable. The device is very compact but it is really effective. Moreover, the number of simultaneous users is unlimited, which is undoubtedly a great plus for me.

Dear Edward, thank you for the review. Your opinion is very important for us. Kindest regards, Support team.

 ·  F  ·  Verified Buyer  · 

Better than any other

I have been using the device for a year already. During all this period I had no signal problems at sea. I recommend it!

Dear Fred, thank you for the review. We would be glad to see you again. Best regards, Support team.

Best marine booster

It goes without saying that good mobile connection when you are offshore is very important. First of all, it ensures safety of marine transportation. I use this booster on my cargo ships to coordinate the actions of motor ships (between ships, between a ship and a dispatcher or owner), to implement transportation schedules, especially when the ships operate far from the coast, on wide sections of reservoirs, lakes, rivers or coastal marine areas. The repeater works very well. Improves both voice communication and 4G internet, and does it perfectly.

Dear George, thank you for the review. We are glad to know that you are satisfied with the product. Best regards, Support team.

 ·  L  ·  Verified Buyer  · 

Good for business

I’m using this booster for some business needs. It supports three frequencies and covers large areas. Now my clients and partners can solve important issues on the phone when they are on board my ship. This is very important for me, especially when it comes to VIP clients.

Dear Lacey, thank you very much for the feedback. We would be glad to see you next time. Kindest regards, Support team.

 ·  S  ·  Verified Buyer  · 


I couldn’t even imagine that the result would be like that. The booster amplifies voice communication perfectly as well as mobile internet.

Dear Amelia, thank you for leaving a review. Keep on enjoying it! Best regards, Support team.

 ·  M  ·  Verified Buyer  · 


This is one of the best marine boosters I’ve ever used. I had a lot of them, but this one is the most effective and it has a huge coverage area – about 2500 m2. So the working principle is the same as in home boosters, the main difference is only in the antennas. The outdoor antenna in the marine repeater is omnidirectional, so it catches signal in 360 degrees around and it’s great. The maximum distance from the shore should be no more than 40 km.

Dear Mark, thank you for the feedback. We would be glad to see you again. Best regards, Support team.

 ·  A  ·  Verified Buyer  · 

Not bad

In general, it’s a good product. It has one indoor antenna included in the set, but I added two more to make the coverage better. It works well but I don’t think it will work the same if you go really far from the shore.

Dear Andrew, thank you for the feedback. We hope it will always help you stay connected while sailing. Kindest regards, Support team.

I own a business which is directly connected with the sea and boats – I have a large touristic yachts club. This wonderful booster is among the many models which I have bought to equip my boats and yachts. This is a 3-band amplifier which improves calls and 4G. I always try to deliver maximum service to my clients, and the availability of mobile communications can be a significant advantage in the passenger transportation market. For example, a passenger comes with a city tour on a boat and decides to call home or friends and tell his or her emotions and impressions of what they have seen. So you see, having a mobile booster is a must in such cases. Now all my clients can benefit from high quality coverage and I never worry about poor reception any more.

Dear Megan, thank you for the review. We are happy to be useful to you. Best regards, support team.

Bought it for my boat

I’ve bought this booster not so long ago. It effectively improves weak signal when I’m in the sea. The order came in a full package. The kit included both 12V power supply and the standard 220V. Amplifies all types of signal for all the providers (but I don't sail too far from the shore). So far I’ve noticed no drawbacks.

Dear Colin, we appreciate your feedback. Please let us know if you have any questions regarding the functioning of the booster. Best regards, Support team.

Case Studies

Felix Thurston, Edinburgh

I've managed to improve my mobile connection on the yacht.

I am fully satisfied with the product. The installation was understandable thanks to the manual included in the full kit. I made a call to the support team of Mobile-signal-boosters to clarify a few points and was able to install the device on my own. Following a few steps described in the scheme I managed to improve the situation with Talk Talk poor signal on my yacht.

Nigel Ezell, Bridlington

I needed a booster for my boat and I found mine!

I am very pleased with the marine mobile signal booster, which I have bought at Mobile-signal-boosters. The model perfectly amplifies not only iD Mobile poor signal, but it also improves weak coverage of other major European operators. The repeater is easily installed and works without errors. It effectively boosts signal wherever I am in the sea.

Steven Hardy, Brighton

Absolutely stunning device!

Thanks to Mobile-signal-boosters store, we were able to solve our mobile signal issues easily and quickly, just as it was promised to us. The information on the website is very detailed, and we could understand everything even despite the fact that we aren't too familiar with technologies. Mobile-signal-boosters customer support helped us choose the booster model, so thanks to them as well!
