Shakespeare Antennas

<h3>About Shakespeare Antennas</h3><p><strong>Shakespeare</strong> is one of the most trusted names in marine communications, with a heritage stretching back to 1897. <a href="/7559-shakespeare-antennas">Shakespeare Antennas</a> traces its roots to Kalamazoo, Michigan, where William Shakespeare Jr. founded the company as a fishing reel manufacturer. The brand's expertise in fiberglass technology — developed through the production of fishing rods — naturally led it into the manufacture of antennas, with a dedicated factory opening in Columbia, South Carolina in 1946. Today, Shakespeare is regarded as a leading global antenna brand serving both recreational boaters and military and civilian maritime customers worldwide.</p><h3>A Legacy of Innovation</h3><p>Over more than a century, Shakespeare has consistently pioneered the technologies that the rest of the marine antenna industry eventually adopted as standard. In the 1960s, Shakespeare engineers developed low-angle radiation techniques for marine antennas — a breakthrough that dramatically improved range and signal quality on the water. The brand also introduced fiberglass radomes, hand-soldered connections, brass and copper elements, and metal ferrules for demanding marine conditions. These engineering milestones underscore why Shakespeare remains the benchmark for performance and reliability in the field.</p><p>From flagship product lines like the <strong>Phase III&trade;</strong> — built for high speeds and high winds — to the broadly capable <strong>Galaxy&reg;</strong> and <strong>Classic Series</strong>, Shakespeare designs antennas to serve the full spectrum of vessels, from kayaks and jet-skis to offshore yachts and commercial ships. The brand's products are also trusted by the U.S. Coast Guard, the U.S. Navy, and military services around the globe.</p><h3>Shakespeare's Marine Antenna Lineup</h3><p>Shakespeare's product catalog covers every major antenna category a mariner could need.
