Digital Antenna 4' VHF/AIS White Antenna w/15' Cable

The Digital Antenna 4' VHF/AIS White Antenna with 15' Cable (model 594-MW) is a high-performance marine antenna engineered for reliable VHF and AIS signal transmission. Designed specifically for vessels requiring dual-band coverage, this antenna delivers the critical gain and low SWR (standing wave ratio) needed for clear communications and automatic identification system functionality in coastal and offshore operations.

The 594-MW features 4.5dB gain optimized across both VHF (156 MHz) and AIS (162 MHz) frequencies, with less than 1.5:1 SWR on each band. This specification ensures minimal signal loss from antenna to transceiver, translating to extended communication range and reliable target detection. The 4-foot vertical element height provides optimal radiation patterns for maritime environments, while the included 15-foot cable offers flexible installation positioning on cabin tops, masts, or rail-mounted brackets. The white marine-grade finish resists salt-air corrosion typical of saltwater duty.

This antenna is suited for operators who require certified dual-band coverage—commercial fishermen, coast guard auxiliary volunteers, marine patrol units, and recreational boaters in regulated waters. VHF and AIS capability allows simultaneous monitoring of voice communications (Channel 16 distress frequency) and automated vessel tracking, essential for maritime safety protocols. The antenna's design assumes integration with standard marine transceiver systems using 50-ohm feed lines.

Digital Antenna manufactures antenna systems specifically for digital signal transmission rather than legacy analog systems, ensuring phase coherence and impedance matching across the dual-band spectrum. The 594-MW represents the antenna manufacturer's commitment to meeting modern maritime communication standards without compromise on gain or SWR performance.
