The Automatic Identification System ( AIS Antenna ) is a monitoring system of naval traffic, useful for navigation safety with difficult meteorological conditions i.e. fog or nocturnal navigation. The VHF Marine AIS antenna system can be operated any frequency between 156-162MHz band thus allows the user to receive/transmit real time information about the traffic in the surrounding area. Antenna Experts has manufactured a range of calibrated antennas exactly for the specific VHF frequencies and for the AIS standards.


The VHF Marine AIS Antennas can receive signals on AIS frequencies very efficiently even when the antenna, because of the boat rolling and pitching, is not perfectly vertical. The high quality raw materials, marine grade stainless steel mounting hardware and the waterproof connector allow our AIS antenna to maintain an excellent performance for many years. The Automatic Identification System Antennais an automated tracking system used on ships and by Vessel Traffic Services (VTS)for identifying and locating vessels by electronically exchanging data with other nearby ships and VTS stations. Automatic Identification Systems Antennas are designed to cover the entire 156-162MHz VHF marine band making these Automatic Identification Systems Antennas highly suitable for all marine territories globally without worrying what frequency allotted by local authority making these Automatic Identification Systems Antennas perfectly suited to the Automatic Identification Systems radar and AIS Engine.


The SD12-160 ultra high performance Automatic Identification Systems VHF marine band stacked dipole array is specially designed as Automatic Identification Systems base station antenna for AIS Automatic Identification Systems covering entire VHF marine band. The SD12-160 is heavy duty marine AIS stacked dipole array features, wide bandwidth, high gain, high power handling capacity, low VSWR, low noise performance and null filling coverage with omni-directional characteristics. This Automatic Identification Systems Antennas stacked dipole array maintains constant gain and VSWR over its 10 MHz bandwidth, making it highly suitable as base station antennas for AIS automatic identification systems used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships, AIS base stations, and satellites and any other multi-channel communication systems.


The wider 180 Degrees horizontal beam-width of Automatic Identification Systems Antennas with high gain features making the VHF Marine AIS antenna highly suitable for Oceanic Information Region to control the inbound and outbound Oceanic traffic. The Vertical stacking distance is factory adjusted for highest possible efficiency. Specially designed center fed phasing harness of Automatic Identification Systems Antennas ensures equal and in phase signal distribution to all the eight dipoles. The SD12-160 high gain AIS stacked dipole array operates at D.C. ground for protection against lightning.


The Automatic Identification Systems Antennas stacked dipole array uses 6063T6 ultra corrosion resistant architectural anodized aluminum, consists of Eight folded dipoles stacked vertically, fed in phase. The center fed dipole of Automatic Identification Systems Antennas ends and cable connections to the dipoles are sealed in polymer epoxy at the end of the boom for protection against weather and imparting rigidity and strength to the dipoles structure. All the fasteners of VHF Marine AIS antenna are made of marine grade SS. The 12 Meters long central mast for mounting the dipoles is shipped in four sections of 3 Meters each for easy of shipping. The dipoles are mounted on a tubular boom made of high strength aluminum alloy, which offers a low resistance discharge path against any lightning strike during the stormy weather.


The N-Female termination of Automatic Identification Systems Antennas sealed in flame retardant heat shrinking tube ensures complete waterproofing. The antenna can be supplied with or without central mast. The marine AIS Automatic Identification System is a VHF radio broadcasting system that transfers packets of data over the VHF data link VDL and enables AIS equipped vessels and shore-based stations to send and receive identification information that can be displayed on an electronic chart, computer display or compatible radar. This information can help in situational awareness and provide a means to assist in collision avoidance. AIS can be used as an aid to navigation by providing location and additional information on buoys and lights.


MC10-156-162 VHF Marine Band High Gain Fiberglass Omni-directional Collinear Automatic Identification Systems Antennas is rugged all weather model uses high class brass and ultra corrosion resistant architectural aluminum alloy and does not require any field tuning or adjustments. The VHF AIS marine antenna is supplied in two segments for easy of handling and shipping. The upper and lower portion of AIS antenna is threaded together to prevent RF inter-modulation and antenna is completely protected within a high-tech ruggedized radome to ensure survivability in the worst environments. The Automatic Identification Systems Antennas termination is enclosed at bottom of the antenna for complete weather protection.


The MC10-156-162 AIS marine band high gain Automatic Identification Systems Antennas collinear antenna is a center fed design which eliminates the distortion of the radiation pattern and ensures nearly a true omni-directional horizontal pattern. The special stub matching is used for smooth VSWR and constant gain over the specified frequency band. The AIS collinear antennas consist of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass tube. MC10-156-162 Automatic Identification Systems fiber glass collinear antenna is suitable for side mounting on the tower and is supplied with mounting hardware, including a non metallic 1.2 Meters (4 feet) long horizontal arm to hold the fiberglass omni-directional antenna at the top, on the side of tower.


Antenna Experts ADY-156-162 dual stacked Automatic Identification Systems yagi antenna design reflects innovative modern antenna construction and designed to increase 3dBi gain in same direction. Antenna Experts ADYS-156-162 AIS dual stacked yagi antenna design reflects innovative modern antenna construction and designed to increase the coverage in different direction. The VHF AIS marine antenna can be installed in two different directions to cover a wider sector or in back to back configuration for bi-directional coverage.


The Automatic Identification Systems dual stacked yagi antenna uses special feed which eliminates the use of folded dipole. The Automatic Identification Systems dual yagi antenna when packed comes with elements removed from the antenna boom for ease of packing and transportation. This AIS yagi antenna can be assembled at site with simple hand-tools. The AIS dual stacked yagi antenna is supplied with a stacking pipe, power divider and phasing harness cable as standard accessories. A cross-over mounting bracket is also supplied with the antenna to mount the central stacking pipe of dual antenna on mast/tower.
