Cellular signal boosters improve coverage in your house and automobile using large antennas. These are the greatest signal boosters for big houses, tiny houses, flats, and automobiles.
SureCall Flare 3.0
The SureCall Flare 3.0 is our top pick for home cellular boosters, retailing at $299.99 and supporting AT&T, T-Mobile, and Verizon. The outside antenna is directional while the inside one is omnidirectional, allowing you to adjust the outside antenna while still receiving signal strength. It covered three rooms in our tests.
weBoost Drive Sleek
The weBoost Drive Sleek ($199.99) is our favourite in-car booster, with a sturdy cradle for almost any smartphone and a USB-A port to charge your phone while boosting it. We obtained approximately 17–18dB more on T-Mobile and Verizon, which was enough to keep our in-car navigation running for that extra mile we needed.
The Cel-Fi Pro, which is designed for apartment dwellers that require a more forceful booster solution, can boost signals by 100dB rather than 72dB and does not need an outside antenna. You just put the antenna inside a window facing in the correct direction and you’re ready to go. There are limitations, of course. Cel-Fi’s solutions only work with one carrier as opposed to all of them, and this booster is considerably more expensive than SureCall’s $299.99 product.
SureCall Fusion2Go 3.0 RV
Car boosters and in-home boosters are both types of RV boosters. The Fusion2Go 3.0 RV from SureCall ($449.99) uses an omnidirectional outdoor antenna—which is helpful because your RV is always in motion—as well as two antenna choices inside. It doesn’t have the same amount of gain as a home booster, with 50dB of peak power, but it’s greater than tiny car boosters. The key to this one is to install the indoor and outdoor antennas correctly, which might be difficult since they must be as far apart as feasible.
HiBoost 15K Smart Link
The majority of consumer signal boosters have a coverage area of no more than 10,000 square feet. The $899.99 HiBoost 15K Smart Link is the widest-coverage consumer booster we could locate, with up to 15,000 square feet of coverage. HiBoost also offers an interesting and unique feature: There are LCD displays on the front of the boosters indicating signal strength on each covered band. For a large house installation, you’ll probably want to split the signal and use extra panel antennas; one panel isn’t enough for 15,000 square feet.
The 600MHz low band, which T-Mobile is best known for, in fact, extends T-Mobile coverage. The FCC has yet to approve any consumer boosters for that band because of relics from old TV stations that took their time vacating it. If you require a boost on the band 71, $7000 ($7,000!) SureCall Force8 is your only option; it must be installed by a professional installer who gets permission from T-Mobile.
