BD-300GDW Overview

Nikrans BD-300GDW is a modern triband amplifier developed for boosting 4G, 3G and GSM signals. This booster model has two indoor antennas that are connected to a repeater box. Thanks to this peculiarity, the amplifier can cover a wider indoor area with a fully stable signal. An LCD screen helps to make the use of the booster even more comfortable. It will show all the important data on the signal power and the network state.

Coverage area

The device has a pretty wide coverage area. It is able to enhance a high quality of mobile connection within the area of up to 300 m². This booster can be suitable for offices, business premises, hotels and other public places.

Signal types supported

BD-300GDW can improve signals transmitted at three different frequency bands: 900, 1800 and 2100 MHz.  All these frequencies are widely used by operators in Europe, Asia and Africa.

As the booster is able to work with three frequencies, it means that the device can solve all your problems with GSM, 3G and 4G reception at the same time.

Benefits and features

This triband amplifier can become a universal solution as it works with different types of signals. Moreover, it has a lot of other benefits that make it a good choice for you.

  • The best price. We offer the most pleasant prices for our boosters on the market.
  • Quick installation. 15-20 minutes will be enough for you to install this booster even if you have never installed any devices of this kind.
  • Support of multiple connections. Even when a lot of mobile devices are using the signal that is improved by your repeater, the signal won’t deteriorate.
  • Automatic control. BD-300 GDW booster tracks the state of the network and the power of the signal. If something goes wrong, it will switch off in order to protect you from any serious consequences.

Kit contents and setup

One of the key advantages of our triband amplifier is the fact that you will receive a full kit that will be fully ready for installation. You do not need to buy any additional accessories. BD-300GDW has two indoor antennas (one should be connected directly to a booster box while the second one is intended for being mounted on the ceiling) and one outdoor antenna. It is highly recommended to install this external antenna on the roof of the building but if it is impossible, you can find a good location somewhere near the window. The kit also includes a booster box that is a central element of the set. It will be responsible for stabilizing the signal while antennas will catch the signal transmitted by your operator and then, after strengthening, send it to mobile devices located within the coverage area of the repeater.

Operating rules

Even if this mobile signal booster is the first one that you see in your life, you will easily manage to install it following our step-by-step instructions provided in a manual that we will send to you together with your booster. This mobile amplifier is absolutely safe for your health. What is more, the repeater is able to reduce the level of radiation emissions produced by your smartphone. That’s why you can install the booster in any rooms, even those where you spend a lot of time every day.

BD-300GDW will become the most efficient solution for any signal issues in different kinds of buildings.

Our professional support managers will be always happy to help you in making the right choice and ordering the best booster in your situation.

Application for booster status tracking

Monitoring of booster’s functioning has never been easier. Now, to have the possibility to track the ongoing working status of your device, it will be enough just to open an app on your smartphone and ensure your booster’s WiFi connection. When everything is done correctly, you can track the functioning of your repeater even when you are far away from your home or office where it is installed.

Safety & Certification

Every Nikrans signal booster is confirmed to be 100% safe for its users, mobile devices and the environment. The absolute safety of devices is proven by the international safety certifications CE and RoHS. Read more about certification of Nikrans equipment here.

This device looks cool. At a first glance, I understood that it is a modern and reliable model. It perfectly improves GSM, 3G and 4G signals at the same time. I like that the booster can send the signal to more than one smartphone simultaneously.
United Kingdom, Verified Buyer
Purchased Nikrans BD-300GDW
I purchased a BD-300-GDW mobile signal booster and Yagi external aerial from My Amplifiers to improve mobile signal strength for an electric car charger that requires a mobile signal to function in Smart mode. My Amplifiers were confident that one of their products would be suitable. When installed the unit did improve mobile signal but the car charger would not regularly function as a Smart unit. I contacted customer service and received a prompt reply from Marina who went over the problem in detail and over the course of several emails made multiple recommendations to correct these . Unfortunately these were not successful and Marina then offered to exchange the booster for no extra charge for an alternative model which she thought would be more successful . This arrived promptly but initially the charger would still not work correctly . Following further communications and much repositioning of the internal aerial the charger eventually functioned in Smart mode, albeit with occasional loss of mobile connection requiring a unit reboot. I was very impressed by the efforts made by Marina to solve my problems. My main negative issue relates to a return postage charge of £60 to send back my initial booster after an alternative model had been sent. The products are sent from and returned to China and the company ask that a fully tracked service is used, hence the cost. As my replacement booster was more expensive than my first model and included an additional internal aerial this offset the postage cost. However because of the high return postage I have downgraded my rating somewhat.

I ordered BD-300GDW to strengthen the signal within my house. And it is working incredibly great. We are so happy as it has been a pain in the ass how we could never talk or use mobile data within our house. Now - thanks to myamplifiers this time has come to an end.While the buying and installation process there where some challenges which were all perfectly solved by the wonderful Catherine from Costumer Service.Thanks so much :-)Happy regards

Good booster. Actually, I do not have any experience that allows me to compare this repeater with anything else. But I am satisfied. It works exactly as I expected.

Purchased Nikrans BD-300GDW
This amplifier is amazingly reliable! Even strong winds and rains do not prevent it from stabilizing the signal. The price is quite reasonable especially given the fact that a lightning surge protector is given for free.
Excellent power Nothing really
