      Top Signal 2X HiBoost 20K Pro with 2 Antennas

      Features of the Top Signal 2X HiBoost 20K Pro

      • Upgraded half‑inch carrier-grade coax cable and two dome antennas deliver double the square foot coverage of the regular Top Signal HiBoost 20K Pro system.
      • Most powerful booster for medium-sized businesses and public buildings.
      • Heavy-duty metal case with heat sink.
      • Easy-to-read backlit LCD display, with uplink/downlink/power status on one screen and optional manual settings.
      • Boost signal for up to 200 simultaneous cellular devices.
      • Includes commercial-grade antennas and components.
      • Carrier agnostic: Works with all major U.S. and Canadian carriers.
      • Boosts 4G LTE and 3G service for voice, text, and data.

      The Top Signal 2X HiBoost 20K Pro is a two-antenna system designed for medium-to-large sized offices or building areas that need improved cell signal reception and have high user demands. The 20K Pro improves both voice and data to reduce dropped calls and missed emails and texts, keeping your business and employees connected with a stronger cell signal.

      This kit includes two inside dome antennas that send amplified signal to the phones in your building.

      HiBoost LCD display and controls The Top Signal 2X HiBoost 20K Pro features a backlit LCD display and controls for gain and power.

      This system doubles your coverage!

      The Top Signal 2X HiBoost 20K Pro system uses the same booster as the standard kit, but includes half‑inch carrier-grade coax cable with half the signal loss of the standard 400 coax. With two ceiling-mounted dome antennas, this 2X system will double the coverage area provided by your system.

      Double the coverage area The ultra-low loss coax cable and two antennas in this system double your amplified cell signal coverage area.

      Who is the Top Signal 2X HiBoost 20K Pro for?

      • Medium-to-large sized offices and buildings with heavy cellular user and data loads.
      • Remote locations with weak cell service.
      • Urban locations with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
      • Areas below ground level, and other places where cell reception is poor.

      How the Top Signal 2X HiBoost 20K Pro works

      The Top Signal 2X HiBoost 20K Pro receives the outside cell signal, amplifies it, and rebroadcasts it inside your office through two ceiling-mounted dome antennas. This allows you to stay connected in areas where cell service is poor, or where your office’s building materials interfere with signals from the local cell tower.

      Works with all major cellular carriers

      The Top Signal 2X HiBoost 20K Pro works with all major wireless carriers in the U.S. and Canada.

      • U.S. carriers, including Verizon, AT&T, T‑Mobile, Sprint, U.S. Cellular, and most others.
      • Canadian carriers, including Rogers, Bell Canada, Telus, Wind, and most others.

      How much area will the Top Signal 2X HiBoost 20K Pro cover?

      This system comes with two dome antennas that broadcast improved cellular signal in a spherical pattern. With strong outside cell signal (−80 dBm or greater), you can typically cover 40,000 square feet of indoor building space with 800 MHz signal. The size of the coverage area depends on many factors, including:

      • Outside cell signal strength received by the donor antenna.
      • Inside building materials. (Cellular frequencies pass through wood framing and drywall more easily than through steel and concrete.)
      • Cellular frequencies used by the carrier and the device. (Lower-freqency LTE and 800 MHz signals travel farther than higher-frequency AWS and PCS signals.)

      Substandard or inadequate conditions in any of these factors will reduce your coverage area.

      Powerful Signal has over a decade of experience designing and installing cellular amplification systems. Please call us at 877‐912‐3444 or contact us online, and we’ll be happy to calculate the coverage area this system will provide in your building and answer any other questions about this amplifier.
