This kit is a ready-made solution to provide the Internet office, garden or private home in areas of uncertain reception. The kit supports LTE 1800, UMTS2100, LTE2600 standards of all mobile operators. Sealed antenna housing provides secure mounting and protection against adverse weather conditions router and modem included. The modem is in close proximity to the antenna, so the loss of microwave signal in the cables from the antenna to the modem is minimal. Thanks to PoE technology, the user gets high-quality Internet without losing the signal in the cable at a distance of up to 100 meters. The device runs under the operating system OpenWRT, providing bandwidth allocation (QoS), firewall, user access control and many other features.

The kit includes:

  1. Directional antenna KAA15-1700/2700 U-BOX in sealed housing
    2. 4G router Kroks Rt-Brd Uw
    3. Huawei E3372 Modem
    4. Patch cord RJ45-RJ45 0.5m long
    5. PoE power injector
    6. Pigtail CRC9-SMA-male - 2 pcs

Installation of the kit is simple and does not require special skills and equipment. When installing the antenna you will need to send it to the base station of the mobile operator and fix it on the bracket. Then connect the antenna wire to the modem and enjoy stable Internet access.

Installation steps:

  • remove the top cover of the antenna;
  • disconnect the USB modem from the router and insert the SIM card into it;
  • connect the pigtail to the modem, insert the modem into the router;
  • install the top cover on the antenna;
  • assemble the external antenna, that is, fasten it to the fasteners and clamp for mounting to the mast or bracket;
  • install a mast or antenna mount bracket (we recommend that you install the antenna as high as possible to ensure line of sight to the base station of the operator);
  • fix the antenna on the bracket (the antenna must be at least 30 cm away from other antennas);
  • connect the twisted pair cable to the power injector into the PoE socket;
  • connect the RJ45-RJ45 patch cord (0.5 m) to the power injector in the LAN socket, the other end to your PC.
