A good multi-carrier car amplifier should have at least +25 dB with the best units topping out at +50 dB. The most powerful multi-carrier units top out at +72 dB gain. Typically, a good multi-carrier home amplifier should have at least +60 dB gain. This prevents overloading the unit and interfering with nearby cell towers. On the other hand, if you have strong outside signal, the booster will apply less gain. If you have weak outside signal, the booster will apply more gain. The actual amplification power you receive will depend on your existing signal strength. The closer you are to -50 dBm, the more reliable your signal is. Essentially, the gain is applied to the captured signal, improving signal strength, which is measured in dBm (decibel-milliwatts). The amplifier receives the signal from the outside antenna and, as the name suggests, amplifies it.Ĭellular signal can only be amplified up to the signal booster's gain value, measured in dB (Decibels).

Due to fewer obstructions and improved line-of-sight with nearby towers, the roof tends to be where the strongest signal is available. Thus, we recommend they be mounted on the roof of your home, business, or vehicle. Ideally, you want the antenna to receive the strongest signal possible for best results. It can affect the power of the signal the amplifier receives. The location of donor antennas is crucial. Homes and offices that only want to boost a single carrier.Having a more focused signal allows the antenna to reach farther than an omni. They are designed to point at the nearest tower. Uni-Directional Antenna (the most common being the Yagi antenna): This antenna (shaped like a triangle) pulls signal from one direction. Homes and offices with multiple nearby cell towers to boost multiple carriers.Homes and offices with medium to strong outside signal.Omni-Directional Antenna: This antenna pulls in signals from every direction. The captured signal is then sent to the amplifier. H3: How Cellular Boosters Work in Homes, Vehicles, and Commercial BuildingsĮxternal antennas (also called donor antennas) capture compatible 5G/4G/LTE c ellular frequencies from different carriers. Keep reading for a deep dive on each component. These units enhance existing cellular signals, not create them.Įnhanced in-building or in-vehicle cell coverage is achieved using: Vehicle Signal Boosters - Designed for cars, trucks, RVs, SUVs, boats, and fleet vehicles.įor a cellular amplifier to work, there must be existing signal, even if it's weak, outside your home, office, or vehicle.In-Building Signal Boosters – Designed for homes, offices, and commercial buildings.There are different types of boosters available that target different needs: The unit receives outgoing signals from nearby cellular devices and sends them to your closest cell tower. Undelivered texts, dropped calls, and unreliable data will be reduced or eliminated.īoosters also work in reverse.

Cellular devices automatically pick up the amplified signal.
