One of the most popular marine mobile amplifiers for boosting poor voice connection on large boats and yachts is Nikrans NS-GD-L-Boats. The full set contains an omnidirectional outside antenna which is able to catch signal from coastline antennas located up to 40 km away in 360° degrees around the ship. Due to the inside antenna the device can be installed on multi-level yachts and large boats as the booster is able to improve signal in the area up to 30 000 ft² (3000 m²). If this is not still enough for perfect coverage you can connect up to 4 inside antennas for total reception in every room of the boat or yacht. One of the main advantages of the repeater is that numerous users can benefit from improved signal at a time without any limitations. The working frequencies of the marine phone amplifier are GSM 900 and DCS 1800 MHz, thus it is compatible with all networks in the UK. As it has already been mentioned, the main function of the device is to better poor voice connection. Nevertheless, you can use the model for improving mobile internet as well provided that your operator uses 900MHz band for 3G or/and 1800MHz band for LTE 4G. The main features of NS-GD-L-Boats are the following:
Shut-off option which prevents the device from breaking down as it automatically turns of in case of set up troubles or bad input signal.
Automatic Level Control (ALC) which adjusts the device to the level of incoming signal.
Manual Gain Control (MGC) which helps to control an incoming signal gain manually.
Automatic Gain Control (AGC) which is used to alter the signal automatically.
2 power supplies (12V and 220V) are included in the kit.
It’s necessary to mention that dual-band marine booster NS-GD-L-Boats has received CE and RoHS certificates which prove its correspondence to the international safety standards. Order your boat booster right now and don’t be afraid to get out of touch in any voyage!

How it works
Marine amplifiers are really unique. Their outdoor antenna does not require aiming as it is able to receive signal from any side. Such a capacity of outdoor antennas ensures that while a boat is moving, your booster can work with the same effectiveness regardless its location. As a usual booster, NS-GD-L-Boats has two antennas. One is for being installed outdoors, and the second one is for spreading the improved signal inside. Nevertheless, it is possible to add some extra indoor antennas to ensure better coverage in different rooms. Though the kit has two cables of the standard length, it is possible to replace them with cables of the length that you need.

I liked this booster. It improves two frequencies - GSM 900 Mhz and DCS 1800 Mhz, but I have noticed that with some operators it amplifies 3G and 4G as they use these bands for mobile internet.
Dear Patrick, thank you for the review. We are glad to know that you liked the booster. Best regards, Support team.

Short cables in the set
The booster itself isn’t bad. It has a large coverage capacity, about 30 000 ft2, and two working frequencies for GSM amplification – 900MHz and 1800MHz. I think that even 3G and 4G can be amplified with this device, although I’m not sure about it. The only problem is that the cables in the set are too short. The one which comes with the external antenna is 10 meters, the one which is with the internal antenna is only 5 meters. I wish they were twice longer than they are.
Dear Lucas, thank you for the feedback. The reason why we don`t include longer cables in the set is that longer cables would lead to signal losses. But your opinion means much to us, we will take it into account and think over a solution to use longer cables in the set. Kindest regards, Support team.

Good for multi-level yachts
The coverage capacity of the amplifier is enormous, so we can use it on our multi-level yacht. We’ve installed two additional antennas and the quality of signal is perfect now. I advise you to do the same thing in case your marine vehicle is large.
Hi Tina, thank you for leaving the feedback. We are glad to know that you are satisfied with the result. With best wishes, the team of Mobile-signal-boosters
· Peter G. · Verified Buyer · 20-11-2022
I’ve chosen this booster for a number of reasons. First and foremost, this is certified equipment, which is safe for health, reliable and long-lasting. The seller provides all necessary documents, certificates, warranties and manuals. Next, the device is very effective and it has a huge coverage area, which is very important for me as I need to amplify poor GSM inside a large zone – about 3000 m2. And one more thing – I can add more inside antennas, thus making the level of amplification a maximum one.
Dear Peter, thank you for the review. Your opinion is very important for us. Kindest regards, Support team.

· Clark Webster (United Kingdom) · Verified Buyer · 08-09-2021
Compatible with all UK operators
I can't go to sea without a booster just because I need to be connected constantly. My previous one was absolutely useless. It didn't improve signal even when I was close to the coastline. NS-GD-Boats-L is another story! It's really effective and powerful. The booster improves signal even when I'm 30 km away from the land. Calls are amplified better than the mobile internet, but in general, I'm satisfied.
Dear Clark, thank you for the feedback. We are happy to know that you are satisfied with the product. Best regards, support team.
· Samantha Thomas (United Kingdom) · Verified Buyer · 23-02-2021
Coped with its task
The main purpose was to amplify poor voice connection, and the booster coped with this task easily and with no problems. We even got 3g when closer to the coastline.
Hi Samanta, thanks for the feedback. Keep on enjoying the stable connection.Best regards, support team.
· Leo G. (United Kingdom) · Verified Buyer · 05-01-2021
Difficult to install
The installation of the booster turned out to be a tough task for me. I had to call the support team for additional consultation. Only thanks to them I managed to set up the device correctly. Thank you!
Dear Leo, thank you for the review. Feel free to contact us whenever you need help. Wishing you all the best, support team.
· Fred · Verified Buyer · 20-02-2020
Much better coverage now
I’d like to say a few words about this wonderful device. It’s not just a simple booster, it’s an advanced cellular signal amplification equipment with great potential. I installed it on my yacht to provide stable GSM signal for my guests. The repeater is a real miracle in the field of signal boosting. As for the price, in my opinion, it’s affordable. Undoubtedly, it’s worth the money you pay.
Dear Fred, thank you for the feedback. Your opinion means much to us. Best regards, Support team.
I have been using this booster for a month already. Before that I had another one with a smaller coverage area. The booster covers all three levels of my yacht.
Dear Nick, thank you for the feedback. We would be happy to see you at our store again. Best regards, Support team.
· Kevin · Verified Buyer · 08-01-2020
Easy to use
I have a booster at home, so I knew what the main working principle of this device is. But using a marine booster turned even to be easier than a home repeater. The components are the same – a booster box, two antennas and mountings with cables.
Dear Matilda, thank you for the review. We are happy to know that you are pleased with the purchase. Kindest regards, Support team.
· Holly Dutton · Verified Buyer · 20-12-2019
With this device my clients never face any signal problems and poor reception when they are far from the shore and base stations of the operator. They like it!
Dear Holly, thank you for the review. We are glad to have been useful to you. Kindest regards, Support team.
· Imogene Gill · Verified Buyer · 12-12-2019
This repeater improves signal significantly. It’s a real salvation when I’m offshore. With its help I keep in touch with my colleagues and my family when I’m at sea.
Dear Imogene, thank you for the review. We are glad to know that your problem has been solved. Best regards, Support team.
· Adam Vaughan · Verified Buyer · 28-11-2019
Worth its money
Some people say that this booster model is too expensive, but I can’t agree with them. It’s common knowledge that cheap components cause equipment failure and breakdown, and this device is effective and reliable.
Dear Adam, thank you for the feedback. Your opinion means much to us. Kindest regards, Support team.
· Marry Derby · Verified Buyer · 31-10-2019
No user manual
I received my order without the user manual in the set. Although the installation wasn’t difficult, I still was upset about it. I had to search on the Internet for the information I needed.
Dear Marry, thank you for the feedback. Please, contact us in case you need any consultation. Kindest regards, Support team.
· Robert Wise · Verified Buyer · 27-09-2019
I like the booster. It has a number of benefits. The system itself is very well-developed. It has auto level control, auto and manual gain control. The set includes two power supplies. No complaints!
Dear Robert, thank you for the feedback. We would be glad to see you next time. Kindest regards, Support team.
· Steve Hardy · Verified Buyer · 18-09-2019
Good Marine Booster
I have been using this marine booster for 2 months already and I am satisfied with it. The signal on board the ship has become strong and stable. The device itself is very simple and unsophisticated.
Dear Steve, thank you for the feedback. We are glad to know that you are satisfied with the booster. Kindest regards, Support team.
· Edward London · Verified Buyer · 09-09-2019
Install additional antennas
When I’ve been reading the reviews, I’ve met a lot of dissatisfied opinions. People wrote that the one and only antenna in the set, I mean the indoor antenna, wasn’t enough to spread the signal around the yacht. So what can I say… the supplier indicates that there is a possibility to install four more additional antennas. Just imagine, FOUR! And that’s what actually I did. And now I have no problems with the signal dissemination. I advise you to do the same.
Dear Edward, thank you very much for the feedback. Keep on enjoying the booster! Kindest regards, Support team.
· Luck Russel · Verified Buyer · 21-08-2019
More than I expected
This 2band booster was more than I expected. I have really underestimated its effectiveness. It improves calls/ GSM without difficulties on my cargo ship. I don’t use it for bettering mobile internet as I am interested only in the quality of voice communication. It looks nice and is easily installed. I have had no problems with this booster so far. I recommend it to everyone who is looking for a good marine repeater.
Dear Luck, thank you for the feedback. We would be glad to see you again. Best regards, Support team.
· Davies Pritchard · Verified Buyer · 12-07-2019
Has an omnidirectional antenna
This is my second booster. The first amplifier, which by the way was purchased here as well, was installed in my countryside house to improve poor reception there. This one was a real surprise for me. I didn’t expect that the external antenna was an omnidirectional one, which receives signal in 360 degrees around the boat. This is a great plus, as you don’t have to look for a good position for your outside antenna, I just mounted it on deck and that’s it. The kit included only one indoor antenna, but I decided to add two more to be sure that the signal would be stable enough. The result is rather positive – I have strong GSM in all the cabins. I recommend it!
Dear Davies, thank you for the feedback. We are glad to know that you are satisfied with the result. Best regards, Support team.
· Emma Jones · Verified Buyer · 26-06-2019
Only one indoor antenna
The indoor coverage of this model is very impressive – 3 000 m2, so in my opinion, that would have been more logical to include at least two internal antennas to disseminate the improved signal more equally around the whole ship. Unfortunately, the supplier put only one antenna, so I had to buy additionally. As for the quality of the product in general – it’s not bad. After the installation the voice connection has become much better.
Dear Emma, thank you for the feedback. We are sorry for the inconvenient. Actually, the majority of our clients found that 1 inside antenna was enough for them. But we will take your opinion into account and discuss the possibility to incude more inside antennas in the set. Kindest regards, Support team.
· Richard Lincoln · Verified Buyer · 15-05-2019
Two adaptors in the set
This boat booster is very convenient to install and to use. The set included everything described at the website. There were even two adaptors - AC/DC 220 V power supply and 12V power adaptor.
Dear Richard, thank you for the review. We would be glad to see you again. Best regards, Support team.
It was a little bit difficult for me to choose the best model of marine signal booster, so I wrote a message to the online support team of Mobile-signal-boosters. The manager eagerly helped me select the best model taking into account all my preferences. The device is effective enough and it works at the same frequencies as my operator.
I faced iD Mobile signal problems practically every time I went to the sea on board my cargo ship. The problem is that the body of the ship is made of steel, so the signal is blocked inside. Moreover, the farther the ship goes into the sea, the worse the mobile signal is. You know, I need to be always in touch, when delivering goods by ship, therefore, I decided to install a mobile signal booster.
I have chosen Mobile-signal-boosters because a friend of mine advised me this company and I haven’t regretted at all. Their product was of a great quality as well as their service. I have never met such a kind and caring attitude towards the client, which is very pleasant. They explained everything I asked and were very patient.
