Find the cell signal booster for your truck or building
Tell us where the signal drops and how strong it is outside. We match it to a kit we carry, or tell you when a booster isn't the fix.
To see a kit, answer where the signal is needed.
How boosters work
A booster is three parts on one cable run: an antenna outside that hears the tower, an amplifier, and an antenna inside that the phones talk to. It works in both directions, so each phone's signal goes back out to the tower the same way.
It can only amplify what the outside antenna receives, which is why the finder asks about bars outside rather than inside. Metal siding, concrete and coated glass keep a good signal out of a building, and a truck cab does the same. A booster carries the signal past them. Where there's no signal outside, there's nothing to carry.
The coverage on the box is the manufacturer's best case, with a strong signal outside. That's why HiBoost rates its 15K Smart Link at 7,000 to 15,000 sq ft rather than one number. FCC rules give vehicle kits less gain than building kits: the weBoost Drive Reach tops out at 50 dB and the weBoost Office 200 at 72 dB, and a vehicle kit serves the phones in one cab.
Every consumer booster has to be registered with your carrier before you use it, a short online form per carrier. If what you need is backup internet for card terminals and the office network, that's a cellular router, not a booster. The full buying guide covers both, and every kit we carry is on the signal booster shelf.
