Product Description

Features of the Nextivity CEL-FI GO G43 4-antenna installer’s kit

  • This system is available to integrators and installers for custom installation with up to 50,000 ft² of indoor cellular coverage. question mark inside a circle
  • The CEL-FI GO G43 is a commercial cellular amplifier solution for small offices, “small box” retail spaces, restaurants, banks, branch offices, and large custom homes that need improved indoor cellular coverage for employees, customers, homeowners, and guests.
  • The GO G43 is the most powerful “off-air” cell phone signal amplifier in its class, providing up to 100 dB gain—hundreds of times more than competing small-office amplifiers and large-home boosters.
  • The GO G43 amplifies 6 bands of 5G/4G frequency simultaneously for Verizon, AT&T, and T-Mobile cellular networks. question mark inside a circle
  • The system’s 3 outside donor antennas—one for each carrier—are mounted on the roof. The 4 inside dome antennas mount in drywall, drop, and hard deck ceilings.
  • The GO G43’s 15 dB of echo cancellation gives the amplifier to ability to continue operating even when the outside and inside antennas are close enough to cause oscillation in other cell signal boosters. question mark inside a circle
  • Remote system monitoring via the Nextivity WAVE Portal provides real-time system performance data.
  • Free phone installation support, with industry-leading lifetime technical support from Powerful Signal, the leader in improved in-building cellular signal.

Keeping customers, staff, and systems connected through reliable cellular coverage, CEL-FI GO G43 is an “off-air” solution that brings strong cellular signal from outside the building indoors. A GO G43 system improves coverage for up to three carrier networks, enabling strong in-building connectivity for in-store digital couponing, payment systems, backup or redundancy for other networks, inventory management, and much more.

This installer’s kit includes commercial-grade components, including 3 outside directional antennas, 4 inside dual-mount dome antennas, a 500′ spool of TS-400 coax cable, and 24 N-male EZ-crimp connectors.

How the CEL-FI GO G43 works

  1. Three rooftop-mounted antennas (one for each carrier) receive outside cellular signal.
  2. The received signal is sent via coax cables to the GO G43 amplifier, which increases the signal gain and sends it downline through one or two coax cables.
  3. The amplified signal is rebroadcast by four inside server antennas distributed throughout the interior of the building where improved signal is needed.
  4. The GO G43 amplifier also sends signal back to the cell towers with increased gain, improving cellular communications in both directions.

This installer’s kit includes all of the components in the diagram above, plus 500 feet of TS-400 coax cable and 24 crimp connectors for cutting and terminating cables to the exact lengths needed in your building. (Crimp and cable prep tools are available as optional add‑ons.)

Coverage Areas

The CEL-FI GO G43 in-building cellular solution can provide indoor coverage for up to 50,000 square feet or more (depending on outside signal strength). This makes it an ideal solution for small and mid-sized businesses and large homes.

Buildings that would benefit from a GO G43 solution include:

  • Small to mid-sized offices & call centers
  • Gas stations, convenience stores, mini-marts
  • Full-service & fast-food restaurants
  • Banks & other businesses with branch offices
  • Gift shops, clubhouses, waiting areas & other small retail spaces
  • Small warehouses & industrial centers
  • Below-ground-level parking garages
  • Charging stations
  • Custom homes & home offices
  • Guesthouses and employee living quarters

Optional plenum air coax cable upgrade

The CEL-FI GO G43 system is typically installed using TS‑400 coax cable to connect the amplifier to the outside and inside antennas. If your building requires fire-rated cableexternal link icon in plenum spaces, please ask us about upgrading to half-inch plenum air coax. Plenum cable fully meets state and federal building codes.

Plenum cable also has nearly half the signal loss per foot of cable compared to TS‑400 coax cable, providing stronger signal from your GO G43 booster and a wider indoor coverage area.

(Plenum air cable is available at additional cost. Call Powerful Signal at 435-634-6800 for details.)
