850 PCS1900 LTE2600 GSM CDMA800 Tri-Band 23dBm 3G 4G LTE Mobile Signal Booster
A cell phone signal booster is a repeater system that amplifies reception in various directions by adding gain or power. The external antenna receives and transmits signals to cellular towers with enhanced power and sensitivity, typically providing between 7 dB and over 10 dB gain. Coaxial cable serves as the system's conduit and contributes to transmission loss.
The primary function of this cellular signal booster is to capture existing cell phone signals around your vehicle, office, workstation, or home, amplify them, and rebroadcast the strengthened signal to areas with weak or no reception. While some models integrate the indoor antenna and amplifier into a single unit, this system typically features separate components including an amplifier, external antenna, and internal antenna. Optional accessories include an Attenuator (reduces unwanted frequency signals), Lightning Surge Protector, Splitter, and Tap.

Input & Output Signal Strength Indication: Displays specific uplink and downlink measurements in dBm for user clarity
Manual Gain Adjustment: Users or engineers can independently adjust uplink and downlink gain using "+" and "-" buttons below the screen
Automatic Gain Control (AGC): Dynamic gain adjustment feature with 31dB range
Smart Mode (AUTO Mode): Automatically adjusts gain according to environmental conditions (manual adjustment disabled in this mode)
Manual Mode: Allows manual gain configuration with automatic safety protocols
Auto Shut Down Protection: Temporarily stops RF function when input power exceeds safe operating range, with automatic restart capability
