How much separation distance is required between the tower antenna and the device antenna?

Print Friendly and PDF Print

It depends. Each weBoost signal booster has a specific Minimum Required Separation Distance between the tower antenna and the device antenna that MUST BE STRICTLY OBSERVED. 

To find the MRSD for your specific booster model, refer to the Installation Guide that came with your booster. If needed, you can download the Installation Guide for your booster here.

As a general rule, an indoor signal booster providing 50dB of gain requires 40 feet of separation between the tower antenna and device antenna. A 60dB gain booster should have at least 75 feet of separation.

PLEASE NOTE: Separation is measured as a straight line between the two antennas. Separation is NOT measured by the length of cables that connect the two antennas to the booster.

For a vehicle booster installation, it is best to place the tower antenna either centered on the vehicle roof or toward the rear of the roof.

The metal roof of your vehicle acts as a shield between the two antennas, making antenna placement a bit less critical for vehicle boosters.

If antennas are placed too close together, the booster may experience oscillation. Oscillation occurs when the antennas pick up each others signals and create a feedback loop.

When this happens the booster will immediately shut down to prevent damage to the mobile network, and will not resume operation until the separation distance issue is corrected.

Typically, a red light displayed on a weBoost signal booster indicates that oscillation has been detected and prevented. If this occurs, increase the straight-line distance between the two antennas.

The signal booster unit itself does not require minimum separation distance from either the tower antenna nor the device antenna. The Minimum Required Separation Distance must be observed between the two antennas, and is critical to your booster's continued operation.
