Product Description

The zBoost TRIO Xtreme REACH solves missed and dropped calls and slow data inside your home. The ZB585X-V or ZB585X-A boosts signals for Verizon or AT&T 4G LTE data as well as voice and text for all major carriers.

The zBoost ZB585X-V or ZB585X-A captures the marginal to reliable cellular signal you have outdoors and rebroadcasts it indoors, up to 5,500 square feet, so you can enjoy clearer, faster and more reliable service without interruption.

Everything you need is included: amplifier base unit, indoor whip antenna, power supply, 50 feet of RG-6 cable, high-gain external antenna, and mounting hardware.

Benefits Include:

  • High performance tri-band signal booster - coverage up to 5,500 sq. ft. (up to 78 dB system gain)
  • Ideal for larger residential spaces that have reliable outside signal or for smaller spaces that have weaker outside signal
  • Reduces dropped and missed calls and provides faster 4G data performance for multiple simultaneous users
  • Boosts performance for iPhone, Samsung, Android and other phones and mobile devices
  • Compatible with mobile phones and devices operating on Verizon 4G LTE, CEL (800 MHz) and PCS (1900 MHz)
  • Automatically operates at maximum gain - no manual adjustments needed
  • Extends phone battery life (phone uses less power when the indoor signal is stronger)
  • Designed in Silicon Valley - Made in North America


The coverage area you can expect from any signal booster kit depends on the signal strength outside the building.

Strong outdoor signal (5 bars) up to 4,500 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 2,600 sq. ft. coverage
