Why we should buy mobile signal repeater/ signal booster/ GSM amplifier: Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.Unfortunately, there are still some places where one can find themselves “out of coverage”Usually those places are either too far from the cell phone base station or located inside underground constructions, for example: - Parking lots, tunnels. - Big stores, office buildings. - Cars, boats etc. - House in remote areas etc. How is mobile phone signal repeater GSM/DCS/ 2G/3G/4G WORKING ? - The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone amplifier through the connection cable (coax). - After the signal is accepted by the phone amplifier, the device amplifies it. - Then this amplified signal goes through the connection cable (coax) to the inside antenna. - And after that, the amplified signal transmits to the cell phone. A regular repeater 3G consists of: - 12dB outdoor antenna. - 3dB indoor antenna. - RG6-50 OHM indoor Coaxial Cable-5m. - RG6-50 OHM outdoor Coaxial Cable-10m. - Mounting accessories. - AC power supply. user manual
