How the Booster/Repeater Works
  1. Outside antenna receives signal from nearest mobile base station
  2. Signal travels through coaxial cable to the repeater
  3. Repeater amplifies the weak signal
  4. Enhanced signal travels to inside antenna via coaxial cable
  5. Inside antenna transmits improved signal to mobile devices
