Shakespeare 5228-4 4' Heavy Duty Galaxy Extension Mast White

The Shakespeare 5228-4 Heavy Duty Galaxy Extension Mast is a 4-foot marine antenna extension designed for heavy-duty applications where additional antenna height is required. This robust fiberglass mast features a white finish that resists UV damage and corrosion in harsh marine environments.

Key Features:

• 44 inches of extended antenna height for improved signal reception
• 1"-14 thread male upper ferrule and female lower ferrule for secure mounting
• Stainless steel ferrules provide superior corrosion resistance
• Heavy-duty fiberglass construction for strength and flexibility
• Compatible with Shakespeare Galaxy and other standard 1"-14 thread antennas
• White finish complements most marine electronics installations

Installation Note: When using multiple extension masts, upper support is required if the total antenna length exceeds 8 feet. This prevents excessive flexing and potential damage in high-wind conditions.

Ideal for sailboats, powerboats, and other marine vessels where mounting height limitations require antenna extensions. The Galaxy series extension masts are designed to work seamlessly with Shakespeare's full line of marine VHF, AM/FM, and GPS antennas.
