Shakespeare AIS 8' Galaxy VHF/AIS Antenna – 6dB Stainless Steel Ferrule – 5225-AIS
The Shakespeare 5225-AIS Galaxy Antenna is a high-performance 8-foot VHF/AIS marine antenna engineered to deliver clear, reliable communication and enhanced AIS reception for coastal and offshore boating. Designed specifically for VHF radio and AIS transceiver use, this antenna ensures dependable signal strength and range when navigation safety and communication are critical.
Featuring a 6 dB gain, the Galaxy 5225-AIS provides excellent transmission and reception performance, making it ideal for powerboats, sailboats, and yachts operating in open water. The antenna is tuned to support both marine VHF (156–162 MHz) and AIS frequencies (161.975 & 162.025 MHz), allowing one antenna to serve dual purposes without compromising performance.
Built with Shakespeare’s renowned Galaxy fiberglass construction, this antenna includes a stainless steel ferrule for added strength, corrosion resistance, and secure mounting in harsh marine environments. The durable white fiberglass radome resists UV exposure, salt spray, and vibration, ensuring long service life and consistent performance.
The Shakespeare 5225-AIS is compatible with standard marine antenna mounts (sold separately) and integrates easily with most VHF radios and AIS systems. Trusted by recreational boaters and professionals alike, Shakespeare antennas are known for their reliability and industry-leading quality.
