10 Best Cell Boosters 2025 in the United States

The CEL-FI GO G41 is a powerful cell phone signal booster designed to improve coverage throughout a large home or space, with up to 15,000 square feet of coverage. It supports multiple frequency bands (700, 850, 1700/2100, and 1900 MHz), making it compatible with major carriers like AT&T, Verizon, and T-Mobile. One of its standout features is the high gain of 100 dB, which means it amplifies weak signals much more strongly than many other boosters on the market. This translates to faster data speeds and fewer dropped calls, especially in areas where signals are usually weak.

It also supports 5G technology, with current 5G DSS support and an update planned to enable even more 5G features soon. The product comes with two types of indoor antennas (dome and panel), so you can choose the best setup for your home, plus an outdoor antenna for capturing signals outside. Installation requires mounting the outdoor antenna and placing the indoor antennas where you want coverage, which might need some basic setup but is straightforward.

A potential downside is its size and weight, as it’s relatively heavy and large compared to simpler boosters, which might be a consideration for some. It’s fully FCC certified, ensuring it meets regulations and won’t interfere with networks. This booster is ideal for users who need strong, reliable signal coverage across a big area and want future-proofing with 5G readiness. If your coverage needs are small or you prefer a simpler, lightweight device, this might be more than you need.

The package includes both dome and panel antennas, giving you flexible installation options based on your home’s layout. However, at 24 pounds, it’s a bit heavier than typical boosters, so installation might require some effort and possibly professional help. While the booster is fully FCC certified, which ensures safety and legal compliance, it’s designed mainly for fixed residential use rather than portable or multi-user commercial settings.
