The Jetfon AT-3G-DUAL 3G voice and data repeater kit is a commercial-grade signal amplification system precision-engineered to restore high-integrity mobile coverage inside signal-compromised structures and cellular dead zones. Operating continuously across dual-band paths in the 900 MHz and 2100 MHz spectrums, this high-performance system captures weak outdoor network signals and redistributes clear cellular reception indoors. It serves as an essential logistics procurement component for architectural facility management, remote corporate hubs, rural property developments, and high-volume B2B telecommunication and radiocommunication hardware wholesale networks looking to stock turnkey cellular enhancement solutions.
The system is specifically designed to eliminate dropouts and expand coverage in challenging environments, making it highly effective for homes, business venues, small offices, deep basements, and rural houses. A critical engineering feature of the Jetfon AT-3G-DUAL is its integrated “auto shut-off” technology, an automated feedback protection matrix that monitors downlink signals to prevent dangerous saturation or oscillation interference with the telephone provider’s primary base station tower. Built for broad network utility, the hardware provides complete cross-carrier compatibility, expanding voice and data capabilities for all network providers utilizing the 3G 900 and 2100 MHz allocations. Note: The installation of this equipment must be authorized by the operator that supplies the signal to the user.
The core amplifier module handles transmission loads smoothly, featuring a maximum transmission power threshold of <15dBm balanced against a strong maximum gain profile of 60/65 dBm ±3dBm. Housed in a low-profile, wall-mountable metal chassis measuring 150 x 121 x 24mm and weighing under 0.8Kg, the device carries an IP40 protection rating for clean indoor installation. The kit is delivered as a comprehensive, multi-component turnkey package, containing the central booster unit, a 220V power supply (5VDC/2A output), a high-gain external donor antenna, a localized indoor distribution antenna, and a premium low-loss 15-meter external coaxial cable assembly terminated with industrial N-type female RF connectors.
