HiBoost Commercial 20K PRO Amplifier Kit

In Stock

Item Number: 7859
Model: Pro20G-5S-LCD



This enterprise-grade cellular signal booster is designed for large commercial buildings where workers and customers need to stay connected. The HiBoost PRO 20K works with all major North American 2G/3G/4G/LTE carriers, providing a peak gain of 70 dBi on weak cellular signals. It has an outdoor Yagi wide-band antenna that must be aimed at the carrier's cell tower. The signal picked up by the antenna is transferred to the repeater and amplified, then the indoor panel antenna rebroadcasts it for up to 20,000 feet of improved coverage. Note there must be at least 60 feet of separation between the antennas for best performance.

The HiBoost Commercial 20K Repeater Kit has several features to optimize the signal so people will have fewer missed calls and faster downloads. A low-interference streamlined design, bright LCD display and manual gain controls allow you to adjust your enterprise signal booster for better results. The unit also has a durable metal enclosure and a lightning surge protector. All antennas and low-loss cables needed for installation are included with the HiBoost 20K.


  • Coverage Area*: 20,000 square feet
  • All-in-One Kit? YES
  • Compatibility: This amplifier supports 700MHz/800MHz/1700MHz/1900MHz/2100MHz networks (which includes most 2G, 3G and 4G providers in the U.S.). Supported carriers/networks include:
    • Verizon 2G/3G/4G/AWS
    • Sprint 2G/3G/4G — 4G LTE will only be improved where Sprint is using the 1900MHz band. This amplifier does NOT support Sprint's 2500MHz LTE band.
    • AT&T 2G/3G/4G/LTE
    • US Cellular 2G/3G/4G
    • T-Mobile 2G/3G/4G
    • MetroPCS 2G/3G/4G
    • For other carriers, confirm which frequency your provider is using and make sure this amplifier supports it before purchasing! Contact us if you need any assistance.

IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

Installation notes:

  • In order for your system to function properly, you must maintain adequate separation between the outside and inside antennas (if the antennas are too close together, there will be oscillation/feedback between the antennas and the amplifier will shut down). This amplifier requires approximately 60' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • If you cannot achieve adequate separation to eliminate oscillation, the gain on the amplifier will automatically adjust to accomodate, but that will result in a smaller coverage area from the amplifier.
  • The Yagi antenna must be aimed directly at the cell tower - if it is not aimed properly or if there are too many obstructions between it and the cell tower, it will not be effective.
  • The interior antenna should be at least 10' away from the amplifier and should be aimed AWAY from the outside antenna.
