Receiving antenna:

Transmitting antenna:

  • Standard: 2G
  • Amplifier type: 2-band
  • Purpose of the amplifier: for calls and the internet
    to talk
  • Display: yes
  • AGC - Automatic gain control: not

For proper operation of the amplifier, it is necessary to select receiving and transmitting antennas.
The amplifier itself is dedicated only to those who already have an antenna installation.

  • large coverage of up to 2000 m²
  • DC 5V power supply included
  • possibility to choose the type of receiving and transmitting antenna, as well as the length of the cables (at the top of the offer)

What are GSM/4G LTE repeaters used for?

Do you have no coverage on your cell phone or Internet from your mobile network operator at home, office, business, factory floor? A weak signal prevents you from talking freely on your cell phone, and lack of Internet causes nervousness, anxiety and financial loss?

We have everything to solve your problem.

Why amplifiers from us?

Our GSM amplifiers meet the standards of "Electromagnetic compatibility", "On health and safety protection", "Efficient use of frequency resources". The device is also CE and RoHS certified.

Our devices support all networks in a given band. The kits are prepared in such a way that you can install them yourself within 15-20 minutes. We focus on customer convenience - plug&play (plug and use).
