The Top Signal HiBoost 4K Smart Link is a single-antenna system designed for small residences that need improved cell signal reception in two to four rooms. The 4K Smart Link improves both voice and data to reduce dropped calls and missed emails and texts, keeping your family members and friends connected with a stronger cell signal.
This system includes an inside dome antenna and a panel antenna that send amplified signal to the phones in your home. Use whichever antenna works best for you.
The Top Signal HiBoost 4K Smart Link features a backlit LCD display and optional manual controls for gain and power.
Who is the Top Signal HiBoost 4K Smart Link for?
- Small homes or a few rooms in a large home, 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.
Monitor your 4K Smart Link system from your smartphone
HiBoost’s Signal Supervisor app for smartphones helps you set up and monitor your cell signal booster. The booster links to your iPhone or Android via a Bluetooth or WiFi connection. With Signal Supervisor, you can:
- Register your booster via a QR Code or Bluetooth.
- Monitor your signal booster’s status via Bluetooth.
- Set up and receive remote alerts if your booster isn’t operating properly.
- View your booster’s power settings, decibel gain, and dBm output.
- Manage multiple boosters.
HiBoost’s Signal Supervisor app is available for Apple iOS and Android devices.

How the Top Signal HiBoost 4K Smart Link works
The Top Signal HiBoost 4K Smart Link 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 4K Smart Link 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 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 system includes an outdoor directional antenna and an outdoor omnidirectional antenna. It also has an indoor dome antenna and an indoor panel antenna. You may use one outdoor antenna and one indoor antenna. Here are some general guidelines for choosing the right antennas.
Outside (donor) antenna:
- The canister-shaped omnidirectional antenna works best in most situations. An omni antenna gathers signal from all carrier towers in all directions, and it’s also easier to set up.
- The wedge-shaped directional antenna (LPDA) works best if your home has a direct line of sight to a specific cell tower that provides service for your cellular network. The directional antenna is also an excellent choice if another carrier has a powerful cell tower nearby, but you need to bypass that tower in favor of a more distant one operated by your preferred carrier. A directional antennas needs to be tuned, so its setup is more involved than an omni antenna’s.
Inside (broadcast) antenna:
- The ceiling-mounted dome antenna works best in most situations. It broadcasts downward and all around in a spherical shape (similar to the shape of a donut, but without the hole in the middle). It usually gives more broad, even coverage than a panel antenna and is less noticeable than a wall-mounted panel antenna. Installing a dome antenna does, however, require that you have access above the ceiling to pull cable and mount the antenna.
- A wall-mounted panel antenna broadcasts forward in a wedge shape (similar to the beam from a flashlight). It’s a better option if you don’t have access above your ceiling, or if you want to mount the antenna on the outside perimeter of the area you want to cover. It’s also a good option for long, narrow indoor areas.

How much area will the Top Signal HiBoost 4K Smart Link 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 (−95 dBm RSRP or greater), you can typically cover 4,000 square feet of indoor building space with 700 MHz signal. The size of the coverage area depends on many factors, including:
- Outside cell signal strength received by the donor antenna.
- Which outdoor donor antenna your choose. The omnidirectional antenna is easier to set up and will pick up signal from all towers and carriers in a 360° radius. The directional (LPDA) antenna provides stronger signal gain by targeting a specific tower, possibly with access to fewer carriers.
- 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-frequency 700 MHz and Cellular (850 MHz) signals travel farther than higher-frequency PCS (1900 MHz) and AWS (1700/2100 MHz) signals.
Substandard or inadequate conditions in any of these factors will reduce your coverage area.
