Shakespeare 4700-1 1ft Heavy-Duty Stainless Steel Extension Mast

In this review the Shakespeare 4700-1 is shown to be a straightforward, purpose-built extension mast for marine and vehicle antenna needs; its single biggest selling point is simple durability - a heavy-duty stainless steel build and standard 1'-14 thread fittings make it ideal when you need a short, reliable extension to clear an obstruction. The Style 4700-1 is a one-section, 12' long mast that slips into existing installations without adapters, and this review focuses on whether that simplicity and material quality justify choosing it for an antenna clearance job.

Key Features

• Heavy-duty stainless steel construction: Provides corrosion resistance and strength for marine or roadside use where exposure and vibration are common.
• Standard 1'-14 thread male and female fittings: Ensures compatibility with most antenna bases and accessories without additional adapters.
• One section, 12' length: Gives a short but effective extension to lift an antenna over a nearby obstruction while avoiding complex multi-section rigs.
• Simple installation: The single-piece design means quick mounting and removal, useful for temporary clearance or testing positions.
• Purpose-driven design: Focuses on doing one job well - extending and elevating an antenna - which reduces failure points compared with multi-part masts.

Who It's For

The Shakespeare 4700-1 is aimed at boat owners, RV owners, and vehicle electronics installers who need a short, sturdy extension to lift a marine or vehicle antenna clear of a mast, railing, or other obstruction. Its stainless construction and standard thread fittings make it a sensible choice for anyone who prefers a durable, no-frills component that fits existing hardware.

Those who should look elsewhere include users who need adjustable height, collapsible storage, or integrated wiring runs; because this is a fixed one-section mast, it does not replace telescoping masts or multi-section units designed for variable length or compact stowage.

Pros & Cons

Pros

• Robust stainless steel construction that resists corrosion in marine environments.
• Standard 1'-14 male and female fittings make it broadly compatible with antenna hardware.
• Single-section 12' length provides a reliable, low-maintenance extension to clear nearby obstructions.

Cons

• Fixed one-section design offers no adjustability for users who need variable height or compact storage.
