Antennas Direct ClearStream 40" Universal Mast

The Antennas Direct ClearStream Universal J-Mount 40" Mast is a weatherproof, pivoting-base steel pole designed to raise and stabilize larger TV antennas, satellite dishes, and security gear for indoor or outdoor installation.

This 40-inch mast replaces shorter 18" poles to give antennas and devices extra height for improved line-of-sight and placement flexibility. Built from 16-gauge, powder-coated steel and finished in black, the mast resists wind, rain, and snow while the unique J-shaped tube and included pivoting base let you mount on vertical walls, roof edges, or horizontal eaves. The kit ships with all-weather hardware, sealing pads, and clear instructions so you can install quickly without specialty tools.

How does this mast improve antenna placement?

Raising an antenna even a few feet can reduce obstructions and improve reception. The 40" length gives a noticeable height increase over standard masts, while the J-shape helps position the antenna away from surfaces for cleaner sightlines. Use both ends with the pivot base for flexible mounting orientations.

• 40" length increases elevation versus typical 18" masts
• J-shaped design spaces antenna from walls and eaves for better line-of-sight
• Pivots to accommodate vertical or horizontal mounting surfaces

What makes the ClearStream mast durable outdoors?

This mast is built for long-term outdoor exposure with 16-gauge steel and a weather-resistant powder coat. The thicker gauge adds rigidity that helps resist bending under wind load, while the coating prevents rust in wet conditions. All supplied hardware and sealing pads are chosen for exterior use to keep the mount tight and sealed.

• 16-gauge powder-coated steel resists corrosion and wear
• Black finish minimizes visual impact on most roofs and exteriors
• All-weather mounting hardware and sealing pads included for secure attachment

How easy is the installation and what mounting options exist?

Installation is designed to be straightforward for most homeowners and installers. The pivoting base fits flat vertical or horizontal surfaces so you can mount to a wall, roof, or eave without custom brackets. Antennas Direct includes instructions and the necessary fasteners so you can complete the job with standard hand tools.

• Pivoting base adapts to vertical walls or horizontal eaves and roofs
• Both ends of the mast accept the pivoting base for flexible orientation
