    Fairview Microwave has launched commercial marine-grade ship/boat RF antennas that provide accurate positioning with L1 band and multiband capabilities, and offer a 28 dBi gain for reliable positioning.

    Fairview’s antennas offer full-spectrum connectivity and operate within the universal marine frequency range of 156 MHz to 163 MHz and CB-27 MHz, 10m-HAM, ensuring unbroken connections at sea. The antennas are also weatherproof, rated IP67 for water ingress.

    The antennas are offered with three types of mounts, making it easier to integrate into any vessel.

    All antennas are crafted from robust stainless steel or fiberglass for durability and reliable performance. Various antenna lengths are available for users to select based on their signal performance needs.

    The commercial marine-grade ship/boat RF antennas are available on the Fairview Microwave website.

    Tallysman Wireless is offering two new VeroStar marine antennas to its line of GNSS products. The VSP6037L-MAR supports the full GNSS spectrum and the VSP6337L-MAR supports GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/B2a, and NavIC-L5 signals. Both antennas support L-band correction signals.

    Marine vessels often host both Iridium (1616–1626.5 MHz) and Inmarsat (uplink: 1626.5–1660.5 MHz) satellite communication antennas that transmit and receive signals. The VSP6037L-MAR and VSP6337L-MAR VeroStar marine antennas strongly attenuate interference from both signal sources, providing 75 dB to 85 dB of attenuation over Iridium and 85 dB to 95 dB over Inmarsat uplink, enabling clean GNSS signal reception and precise positioning.

    Every VeroStar antenna features a robust pre-filter and a high-IP3 LNA architecture, minimizing de-sensing from high-level out-of-band signals, including 700 MHz LTE, while still providing a noise figure of only 1.8 dB.

    VeroStar antennas provide the best-in-class low elevation angle tracking of the full GNSS spectrum and L-band correction signals. The wideband spherical antenna element enables VeroStar antennas to deliver ±2 mm phase centre variation (PCV), making them suitable for high-precision marine, positioning and machine control applications.

    The VeroStar marine antennas are housed in a rugged and compact enclosure that supports 1-inch pipe thread or 5/8-inch-11 TPI mounting and provides a TNC antenna connector. The antennas have also obtained the stringent IEC 60945 and IEC 61108 marine certifications, making them suitable for challenging marine environments.
