The Fusion4Home is a home cellular signal booster kit for one room up to a small home. It pairs an omni outside antenna with a whip inside antenna and delivers up to 72 dB of gain for talk, text and 4G LTE on all North American carriers. It supports several phones at once, so a household shares one booster instead of buying per-device units. Owners report strong gains where outside signal is weak but usable; results depend heavily on where the outside antenna is mounted and on the strength of the signal at the roof.

Owners rate it well overall and most praise the jump in bars and call reliability once it is installed. Complaints center on setup effort, coverage that falls short of a whole house, and results that vary with outside signal.
