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.

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.

Case Studies

Mike Tromper, Swansea

Highly effective for my boat.

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 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.

Hector Blanton, Brighton

iD Mobile signal problems were so irritating!

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.

Willis Rigney, Dundee

Reliable store.

I have chosen 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.
