What’s my cell signal strength?
The HiBoost CommLink 20K is a professional-grade cell signal amplifier engineered for residential, office, and light-commercial environments that need improved cell signal reception. Delivering up to 72 dB of system gain, the CommLink 20K improves voice and data to reduce dropped calls and missed emails and texts, keeping your business, employees, residents, and/or guests connected with a stronger cell signal.
The HiBoost CommLink 20K Long-Range commercial cell signal booster, part of Powerful Signal’s exclusive Top Signal Series, pairs the CommLink 20K amplifier with our top-of-the-line high-gain outdoor antennas—ideal for properties in fringe coverage areas or sites where the nearest cell tower is far away. The extra antenna gain captures more outside signal, expanding your usable indoor coverage and delivering stronger, more reliable cell service.
This system includes inside dome or panel antennas that send amplified signal to the phones in your building. You may customize your CommLink 20K Long-Range system by adding inside antennas, up to a total of four.
With an Ethernet connection, you can monitor, administer, and receive email alerts from your HiBoost CommLink 20K system from any device with a web browser and internet access. You can also administer multiple HiBoost systems at one or multiple locations.

The HiBoost CommLink 20K receives the outside cell signal, amplifies it, and rebroadcasts it inside your office or home through one to four ceiling-mounted dome antennas or a wall-mounted panel 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.
The HiBoost CommLink 20K works with all major wireless carriers, including Verizon, T-Mobile, AT&T, Boost Mobile, UScellular, GCI Alaska, and most others.
It operates on common cellular frequencies.
This system gives you the choice of an outdoor directional or omnidirectional antenna and up to four indoor dome or panel antennas. Here are some general guidelines for selecting the right antennas.
Outside (donor) antenna:
Inside (broadcast) antenna:
If you’re still not certain which antennas will work best for you, please call us at 435-634-6800. Our technical support representatives will be happy to discuss your specific requirements and give you a recommendation based on years of professional experience.
With strong outside cell signal (−95 dBm RSRP or greater), the HiBoost CommLink 20K Long-Range can cover up to 22,000 square feet of indoor building space with 700 MHz signal—at least 10 percent more than the standard CommLink 20K kit. The high-gain donor antennas are especially valuable when outside signal is weak, where the extra antenna gain translates directly into more usable indoor coverage. The size of the coverage area depends on many factors, including:
Substandard or inadequate conditions in any of these factors will reduce your coverage area.
Powerful Signal has years of experience designing and installing cellular amplification systems. Please call us at 435-634-6800 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.
