Cell Booster Antenna Separation for Installing Amplifiers
Antenna Separation for Installing Amplifiers
Proper cellular antenna separation is essential in order to prevent signal oscillation, or feedback, that can interfere with the tower or shut your cellular booster down, temporarily. Separation is measured in a straight line from the exterior antenna to the closest interior antenna. The closest allowable separation depends on factors such as an booster's dB gain level, building location, or the building materials of the structure.
