Features of the Top Signal 2X HiBoost 10K

  • Upgraded commercial-grade 400 coax cable delivers double the square foot coverage of the regular Top Signal HiBoost 10K system.
  • Provides improved signal for large homes and small offices.
  • Sturdy metal case.
  • Easy-to-read backlit LCD display, with uplink/downlink/power status on one screen and optional manual settings.
  • Boost signal for up to 150 simultaneous cellular devices.
  • Choice of outside and inside antennas at no additional charge. (Get help picking the right antennas.)
  • 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 10K is a single-antenna system designed for large homes that need improved cell signal reception throughout the house. The 2X 10K improves both voice and data to reduce dropped calls and missed emails and texts, keeping your family members, friends, and guests connected with a stronger cell signal.

This kit includes one inside dome or panel antenna that sends amplified signal to the phones in your home.

HiBoost LCD display and controls The Top Signal 2X HiBoost 10K features a backlit LCD display and controls for gain and power.

This system doubles your coverage!

The Top Signal 2X HiBoost 10K system uses the same booster as the standard kit, but includes ⅜‑inch 400 coax cable with half the signal loss of the standard 240 coax. This 2X system will double the coverage area provided by your inside dome antenna.

The 2X system also includes an upgraded outdoor omni antenna that provides better signal gain to and from the cell tower.

Double the coverage area The low-loss 400 coax cable in this system doubles your amplified cell signal coverage area.

Who is the Top Signal 2X HiBoost 10K for?

  • Large homes with typical cellular user and data loads.
  • Residences in remote locations with weak cell service.
  • Urban environments with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Basements and other below-ground rooms where cell reception is poor.

How the Top Signal 2X HiBoost 10K works

The Top Signal 2X HiBoost 10K receives the outside cell signal, amplifies it, and rebroadcasts it inside your home through a ceiling-mounted dome antenna or wall-mounted panel antenna. This allows you to stay connected in areas where cell service is poor, or where your home’s construction materials interfere with signals from the local cell tower.

Works with all major cellular carriers

The Top Signal HiBoost 10K works with all major wireless carriers:

  • 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.

It operates on common 4G/3G cellular frequencies.

  • 700 MHz (SMH) bands 12, 13, 17.
  • 850 MHz (Cellular 850) band 5.
  • 1700/2100 MHz (AWS) band 4.
  • 1900 MHz (PCS) bands 2, 25.

Which antennas should I choose?

This kit gives you the choice of an outdoor directional or omnidirectional antenna, and an indoor dome or panel antenna. Here are some general guidelines for selecting the right antennas.

Outside (donor) antenna:

  • The cylindrical omnidirectional antenna works best in most circumstances. The omni gathers signal from all carrier towers in all directions.
  • The wedge-shaped LPDA directional antenna works best if your building is in a remote location with one single, distant tower providing cell service for your area. The LPDA is also an excellent choice if there’s a powerful cell tower nearby, but you need to bypass that tower in favor of a more distant one operated by your preferred carrier.

Inside (broadcast) antenna:

  • The ceiling-mounted dome antenna works best in most circumstances. It broadcasts downward in a spherical shape (similar to the shape of a light bulb), and usually gives significantly more coverage than a panel antenna. A dome is also less noticeable than a wall-mounted panel. The dome antenna does, however, require access above the ceiling to pull cable and attach it to the antenna.
  • The wall-mounted panel antenna works best if you don’t have access above your ceiling, or if you need to mount the broadcast antenna on the outside perimeter of the area you want to cover. The panel antenna broadcasts forward in a wedge shape (similar to beam from a flashlight).

If you’re still not certain which antennas will work best for you, please call us at 866‑912‑3444. Our technical support representatives will be happy to discuss your specific requirements and give you a recommendation based on years of professional experience.

How much area will the Top Signal 2X HiBoost 10K cover?

This system comes with one dome antenna that broadcasts improved cellular signal in a spherical pattern, or a panel antenna that broadcasts in a horizontal cone shape. With strong outside cell signal (−80 dBm or greater), you can typically cover 20,000 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.
  • Which indoor broadcast antenna your choose. (A dome antenna typically provides better signal coverage than a panel 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.
