Shakespeare 4700-1 12" Mast Extension Stainless Steel 1" 14 Thread

The Shakespeare 4700-1 12" Mast Extension Stainless Steel 1" 14 Thread is a heavy-duty antenna or mast extension designed for marine, communications, and tactical applications where vertical clearance must be increased. This one-foot extension allows operators to raise antennas, sensors, or communication equipment above obstructions such as vegetation, structures, or terrain features that would otherwise compromise signal strength or line-of-sight performance. Ideal for mobile operations, emergency response teams, and field installations, this extension mast delivers the vertical gain needed in confined or challenging deployment environments.

Constructed from marine-grade stainless steel, the Shakespeare 4700-1 resists corrosion and weathering in saltwater, coastal, and high-humidity environments where standard steel would degrade rapidly. The extension features a standard 1-inch 14-thread male and female coupling design, enabling seamless integration with compatible Shakespeare antenna systems and other mast assemblies using the same thread specification. The single-section design minimizes assembly complexity and weight while maintaining structural rigidity, with a net weight of 2 lbs that permits portable installation and repositioning without specialized equipment.

This extension mast is most effective in military, law enforcement, maritime, and emergency communications roles where antenna height directly impacts performance and range. The stainless steel construction makes it suitable for harsh outdoor conditions including salt spray exposure and extreme weather, while the 1-foot length provides a practical balance between gain and portability. Installation requires only hand-tight connection at both the male and female 1" 14-thread fittings—no tools necessary. Verify compatibility with your existing Shakespeare mast or antenna system before purchase to ensure matching thread specifications.
