Model SD12-160 155-165MHz 12 dBd. Gain Download Datasheet Download Manual Post Enquiry

High Gain Marine Antenna

Design Features : The SD12-160 ultra high performance VHF marine band stacked dipole array is specially designed as AIS base station antenna for AIS Automatic Identification Systems covering entire VHF marine band. The SD12-160 is heavy duty 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 AIS 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 with high gain features making the 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 ensures equal and in phase signal distribution to all the eight dipoles. The SD12-160 High gain stacked dipole array operates at D.C. ground for protection against lightning.

Constructions : The 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 ends and cable connections to the dipoles are sealed in epoxy at the end of the boom for protection against weather and imparting rigidity and strength to the dipoles structure. All the fasteners 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 antenna 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.
