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 ultra-thin dome or regular dome antennas that send amplified signal to the phones in your building.
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 ultra-thin or dome antennas, this 2X system will double the coverage area provided by your system.
In a large building, office, or warehouse, you’ll get the best results and performance from a Top Signal 2X HiBoost 20K Pro with a custom design and professional installation.

This system comes with two ultra-thin or regular 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:
Substandard or inadequate conditions in any of these factors will reduce your coverage area.
