Powerful Signal hasn’t tested the Top Signal MagMAX mount using a digital force gauge, so we couldn’t give you an exact number in pounds or Newtons.
We have tested with the Top Signal 5G OTR antenna without the optional antenna mast, and it stays attached to a steel vehicle roof at interstate highway speeds (80 MPH). The weBoost Drive OTR will also work in the same short configuration.
For running with an OTR antenna with a mast extension, upgrade to the Top Signal MagMAX 3X mount.
