Shakespeare 6018-R Phase III VHF Antenna - 17 6 ft, 9dB Gain

In this review the Shakespeare 6018-R Phase III VHF antenna is assessed for small-boat and coastal mariners who need a straightforward VHF solution. The bottom line: it is a simple, purpose-built marine antenna best suited for owners who want reliable VHF performance without complex installation or extra features. Our review finds the antenna delivers the core benefit implied by its description - consistent marine band reception and transmission - making it a sensible upgrade for vessels that require a traditional 17 ft 6 in VHF mast with a stated 9dB gain.

Key Features

• 17 ft 6 in length: Provides vertical reach that helps improve line-of-sight communication for coastal and nearshore VHF use.
• Phase III design: A proven antenna geometry that aims to balance bandwidth and pattern stability across the marine VHF band.
• 9dB gain: Higher gain than many stubby or base antennas, which can extend usable range under typical conditions.
• Marine band focus: Tuned for VHF marine frequencies so users get performance optimized for common ship-to-ship and ship-to-shore channels.
• Simple fitment: A straightforward antenna form factor that integrates with standard marine mounts and feedlines without added complexity.

Who It's For

The Shakespeare 6018-R is best for recreational boaters, fishermen, and small commercial operators who need a dependable VHF aerial and prefer a conventional 17 ft 6 in vertical antenna. It suits vessels that operate in coastal waters where improved gain and a stable radiation pattern help maintain clear channel communications.

Those who should look elsewhere include sailors who need an ultra-compact, folding, or hidden antenna for aesthetic reasons, and high-end operators who require integrated features such as built-in GPS receivers or specialized mounting hardware. This model focuses on core VHF performance rather than extras.
