Product Description

Features of the Nextivity CEL-FI GO G43 window-mount DAS system

  • This CEL-FI GO G43 solution has been custom designed by Powerful Signal for offices and large dwelling units that do not have access to the roof to mount a donor antenna.
  • Instead of a roof-mounted antenna, this system uses three window-mounted panel antennas, one for each major U.S. cellular carrier. Each high-performance Top Signal EDGE panel antenna adheres to the inside of an exterior window with a window-mount tray and 3M hook-and-loop adhesive.
  • Three Top Signal EDGE dome antennas—mounted in drywall, drop, or hard deck ceilings—provide improved signal to smartphones and other cellular devices inside your building.
  • The CEL-FI 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 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
  • Free phone installation support, with industry-leading lifetime technical support from Powerful Signal, t+he leader in improved in-building cellular signal.

Keeping customers, staff, and residents connected through reliable cellular coverage, CEL-FI GO G43 is an “off-air” solution that amplifies cellular signal without a roof-mounted donor antenna. A GO G43 system improves coverage for up to three carrier networks, enabling strong in-building connectivity.

This GO G43 solution has been custom designed for high-rise offices, condominiums, and apartments on the lower or middle floors of high-rise buildings. It’s also a good solution for large, custom homes with HOA rules that prohibit installing outside antennas.

This custom solution, available only from Powerful Signal, gives you the choice of preterminated coax cables in various lengths or an installer’s kit with a 500′ spool of TS-400 coax cable and 24 N-male EZ-crimp connectors that you can cut and terminate to custom lengths in your building.

How the CEL-FI GO G43 window-mount system works

  1. Three window-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 three coax cables.
  3. The amplified signal is rebroadcast by three 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.

Coverage Area

While the CEL-FI GO G43 amplifier can provide indoor coverage for up to 50,000 square feet or more, the decreased signal strength and quality received by the window-mounted panel antennas will likely reduce the maximum coverage area inside your building.

If you have any questions about how much indoor area this solution can provide in your building or home, please contact Powerful Signal—we’ll be happy to evaluate your available signal strength and give you an estimate on the amount of coverage you can expect.

Optional plenum air coax cable upgrade

This CEL-FI GO G43 system is typically installed using 400-type 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.)
