1.The antenna is to be placed outside of the car window.

2. The square repeater is to be placed inside of the car window (Make sure the square repeater is aligned right below the antenna).

3. This device is to be used in automobiles only, if you want to use this at your home PLEASE READ DESCRIPTION BELOW.

4. For best signal improvement, the booster must be installed at least 3 feet away from your phone or installation location. This spacing allows the passive antenna to capture and redirect existing tower signal effectively.

DISCLAIMER: Passive Booster (Non-Amplified): Does not create or amplify signal — only redirects existing signal from nearby towers. Performance Depends on Environment: Car construction, terrain, and carrier coverage impact results. Not for zero-signal areas: A minimum existing signal is required for the passive booster to redirect.
