How it works

NS-GDW-L-Boats is an amazing choice for owners of large boats and yachts. An unlimited number of users can enjoy the benefits of this device simultaneously. Originally, the booster has one antenna to be installed outdoors as high as possible (it is able to receive the signal transmitted from a cell tower even if it is situated at a distance of 40 km) and one antenna to be installed inside as its task is to spread the amplified signal among users. Nevertheless, you can increase a number of inside antennas which will guarantee the higher quality of mobile connection. The device has power supplies of two types (12V and 220V), so, you won’t have any troubles with switching your device on.

Good marine repeater

The repeater is effective for 2G and 3G, less for 4G (2-3 bars on my boat). It has an omni-directional antenna, so I didn’t spend much time trying to guess where to install it, as it catches signals from all the providers, on condition that their masts are located within up to 40 km distance. The coverage area is enough for my boat. So I'm satisfied with the purchase.

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

Case Studies

Ed Sobers, South Shields

Great products and quality!

Mobile-signal-boosters.co.uk offers great products, fast shipping and caring service. My order had been processed immediately and I received my marine signal booster in three days. The company sent me the full kit, which included interior and exterior antennas with cables and the booster box. All the mounting details were in the parcel as well. So there was no need to buy anything additionally.

Jeff Cunard, Weymouth

Constant problems with a mobile signal disappeared.

iD Mobile is one of my favourite operators. The network is always in demand due to a wide range of attractive tariffs, numerous bonuses and good quality of voice communication. Nevertheless, this doesn’t mean that the operator never faces signal problems. As for me, I had to cope with iD Mobile signal issues any time I went to the sea on board my cargo ship.

Ron Arebdale, Ayr

I've purchased two boosters and happy with both of them.

I have turned to Mobile-signal-boosters.co.uk twice. The first time was when I was choosing a mobile phone signal booster for my parents’ house located in the village with iD Mobile poor coverage. The second time I purchased a mobile booster for my boat in order to stay in touch when I am out in the sea. I would like to mention that I was pleased in both the cases, when I worked with the company. They offer effective solutions to any signal problems.
