You don't want to come back because the bracket slipped or rusted.

Premium Quality Materials

This heavy duty antenna mount is made entirely of solid stainless-steel parts that will not rust or discolor your building.

The base is precision stamped from a single piece of metal for maximum strength with no welds to fail.

This bracket will last a lifetime with no maintenance.

Unique Design

Our exclusive locking mechanism allows the mast to be securely mounted at -45, 0 or +45 degrees without fear of slippage and gives the J-Max incredible weight bearing capacity up to 130 pounds.

The optional slide mechanism allows the mast to be infinitely positioned between +45 and -45 degrees to adapt to a variety of installation situations.

Installation Flexibility

Numerous pre-drilled holes simplify installation. The mast tube is reversible for different stand-off distances.

See the User Guide PDF on this listing for all 6 of the assembly positions.

The mast's 1.5 inch diameter accommodates most antenna pole mount mechanisms such as U-Bolts and pole clamps.
