Coverage area

The coverage area of Nikrans NS-300-Multi is around 300 m² (3,200 ft²), which makes the model convenient both for home use and business. You can successfully utilize this booster for mobile phone signal in a 1-2-story private house, apartment, restaurant, supermarket, office, and any other medium-sized room.

Signal types supported

Working at five frequency bands, NS-300-Multi boosts 5G/4G Internet and GSM calls at the main frequencies used by most carriers in Europe and Asia. The frequencies of 900 MHz and 1800 MHz are used for voice calls (GSM). The transmission of 4G signals is realized generally at 800, 900, 1800 and 2600 MHz, as well as 2100 MHz for some carriers. The most advanced 5G Internet is broadcast at 2100 MHz, but 800 and 1800 MHz are also used for this type of connection. The booster also strengthens 3G Internet in the frequency band of 900 MHz where this type of signal is still transmitted. So, it is very important to take into account that, depending on the country and provider, the same type of signal can be emitted in different bands.

FREE Lightning Surge Protector (€30 value)

Savings of 30€ and additional protection as a gift

The lightning surge protector is delivered with each set of LCD-300GD free of charge. This way you get the opportunity to save about 30 euros, because lightning protection is very important for the good operation of the mobile signal booster. This will protect your device's outdoor antenna from lightning strikes. The surge protector comes with a grounding wire and is installed in-line between the amplifier and the external antenna. Thus, one end is screwed to the cable connector coming from the signal amplifier and the other to the external antenna. The lightning surge protector is highly recommended for those customers who live in areas with frequent thunderstorms.

The booster installation is quick and simple, taking approximately 15-20 minutes, and there is no need for any special knowledge. You should follow system requirements, such as ensuring good ventilation and avoiding contact with heating equipment. For the effective work of NS-300-Multi, we recommend installing the outdoor antenna in a spot with relatively stable and strong signal reception.

The booster amplifies the cellular connection within 5-7 seconds, allowing you to phone or surf the Internet without interruptions. The number of mobile devices that can benefit from the enhanced signal is not limited.
