FREE Lightning Surge Protector (€30 value)

Get lightning protector as a bonus and save 30€

You will get a free lightning surge protector with the order of the BD-500GDW signal booster. This is a great opportunity to save about 30€, since lightning protection is essential for the effective work of the mobile booster. The device will protect your outdoor antenna from lightning strikes. The protector includes a grounding wire and it is installed between the booster box and the outdoor antenna. You should connect one end to the cable connector coming from the booster box, and the other one to the outdoor antenna. The lightning protection is strongly recommended for owners living in areas with frequently occurring thunderstorms.

The installation is really easy and takes 15-20 minutes. After the device is turned on, the signal gets intensified in 5-7 seconds.

Like any other electronic equipment, the amplifier should be stored away from heating systems, not exposed to bad weather and protected from lightning.

Now I can’t imagine how we managed to live without this booster.

Stable connection regardless of weather conditions outdoors (earlier during storms and rains we had no signal at all).

I bought this device for my mum as she had terrible mobile connection. She even couldn’t make calls not to mention using mobile internet. We both are satisfied with the quality of this booster.

Excellent device and excellent support team. My mum thought that this device could be dangerous for her health, so I need to explain to her how it works (yes, for our parents this device may seem rather suspicious).

I live in a so-called marginal signal area. Outside my house I might get 3 bars of signal at best. Inside I mostly see one or no bars. Dropped calls have become a rule. As for texting, it would take about 20 seconds for a text to send. I purchased Nikrans LCD-300GDW. Plugged the system in and immediately saw 4 bars on my phone. If you're considering a signal repeater, I highly recommend this thing.

In the area we live the mobile service is terrible. We're lucky to get one or two bars inside the house. After a lot of research, read about this model and decided to give it a try. Installed the system and now we get solid 3-5 bars throughout the house. Internet is outstanding. No more missed or dropped calls. Wish we had done it sooner.

Fabulous product! I work in the middle of a plant. Normally I have no signal at all. I was skeptical at first about how well this would work in my office. The point is to place the antenna and transmitter in the right locations. Instructions are easy to follow. I now have a solid 5 bars, great GSM and 3G coverage. I would highly recommend this product.

I would recommend Nikrans repeater for every office or store owner. My new office is situated on the ground floor of a new skyscraper in business center of Dubai. I spent too much money for rent and don't want to lose clients due to constant dropped calls. Before the weekend I got Nikrans Triband only 10 days after the order. The only problem I had was installation as I have no technical education and know little about such devices in whole.

essential thing for business owners whose offices suffer from weak signal reception

I find it very useful that the device has an LCD display. Looking at the screen, I managed to find a good location for the external antenna really fast.
