Shakespeare 4700 6" Stainless Steel Extension

The Shakespeare 4700 6" Stainless Steel Extension is a marine antenna mast designed to elevate communication and navigation equipment above deck obstructions or water interference. Built from stainless steel with 1-inch, 14-thread standard connections, this 6-inch extension mast increases effective antenna height for improved signal transmission and reception in marine and maritime applications.

The stainless steel construction provides corrosion resistance in saltwater and harsh marine environments, a critical consideration for offshore and coastal operations where equipment exposure to salt spray and moisture is constant. The 0.5-pound weight keeps system load minimal while the compact 2" × 2" × 8" profile integrates cleanly into existing antenna systems. The Shakespeare 4700 mast accepts standard marine antenna components at its threaded interface, making it a straightforward addition to existing antenna arrays without requiring proprietary adapters or modifications.

This extension is commonly deployed to mount VHF marine radios, GPS receivers, satellite TV antennas, or weather instrumentation where clearance above cabin structures or rigging is limited. Operators working in environments where antenna obstruction degrades signal strength—vessel patrol, offshore platforms, or coastal command posts—rely on mast extensions to position equipment above RF-blocking obstacles. The 6-inch length offers a practical compromise between height gain and structural stability without creating excessive top-heavy loads on standard mounting brackets.

Shakespeare antenna systems are established marine equipment standards recognized in commercial, military, and recreational marine service. The 4700 series represents reliable mid-range extension hardware suitable for mission-critical communication needs where equipment downtime is unacceptable.
