The Scanstrut Aluminum PowerTower is designed to mount radomes, open array, and small satcom or TV antennas on the cabin roof, flybridge, or radar arch of your powerboat. This sturdy mount allows the antenna a clear view of the horizon for optimal performance. The heavy-duty aluminum structure features a strong monocoque design with a white powder-coated finish and an aerodynamic shape. An IP65-rated waterproof gland seals the cable entry into the hollow stem. Installation is simple with pre-drilled holes. Includes mounting bolts and watertight base seal. 25° leaning forward (for radome) and aft (for open-array). 7" x 7" base.
