The vibrations of the entire tower is being transferred into the house. It
won’t matter what is on the tower.
The only remedies are:
-Cushion the bracket-to-tower
-Disconnect the bracket if your tower is not a tiltover base or baseplate.
-Add a 2nd bracket mid-way, but this will only change the frequency of the
vibration tone.
-Take the tower down, move the tower location, or switch to wires only
-Live with it
