Digital Antenna 594-MW 4' VHF/AIS Antenna; 4.5 dB Gain – White
Dual-Band VHF / AIS Antenna
4.5 dBi Gain
The 594-MW is engineered to deliver the strongest performance on both VHF and AIS frequencies. With a gain of 4.5 dB and a VSWR less than 1.5:1 across 156–162.5 MHz, this antenna ensures maximum transmit and receive range for marine communication. Built exclusively for digital signals, Digital Antenna’s design provides unmatched clarity and reliability for VHF radios and AIS transponder systems.
Ideal for vessels of all sizes—commercial or recreational—the 594-MW is perfect for use with combined VHF/AIS radios. Each antenna is proudly made in the USA, hand-assembled, hand-tuned, and quality tested for long-lasting performance. The factory-installed mini-UHF connector (less than 3/8" OD) and included PL-259 adapter make installation quick and solder-free.
