3dBi marine FRP antenna (1700mm)—— Lightweight evolution from metal to FRP Looking back at the development of marine communication antennas, it is found that the early metal materials are strong but hard to escape seawater corrosion, and frequent replacement becomes the burden of ship owners. This 1700mm 3dBi Marine Fiberglass Antenna is the result of material iteration and technical optimization, and witnessed the lightweight revolution of offshore communication equipment. At the end of last century, marine antennas mostly used copper or aluminum alloy radiators, which generally weighed more than 2kg. The installation needed extra reinforcement, and rust might appear due to salt spray within half a year. The application of glass fiber reinforced plastic—representing the progress of Fiber Glass Antenna—completely changes this situation: its insulation characteristics are naturally corrosion-resistant, and it has no damage after 5000 hours of salt spray test, and its service life is more than 3 times longer than that of metal antenna, especially suitable for wet and salty coastal environment. In terms of technical parameters, it continues the high standards of maritime equipment: 162MHz frequency band focuses on offshore communication, and it is also compatible with 433/868/915MHz Antenna standards for extended use; 3dBi gain balances signal coverage and energy consumption, and 50Ω impedance matches the mainstream radio interface. Compared with earlier products, the omnidirectional radiation angle is increased to 360°, which solves the problem of signal blind area of metal antenna. The lightning protection design of direct grounding is the targeted optimization of communication safety in thunderstorm-prone sea areas. From heavy metal poles to 1700mm lightweight glass fiber reinforced plastic, from frequent maintenance to "multi-purpose in one package", every detail of this antenna condenses insight into the demand of offshore navigation and becomes the first choice for upgrading communication equipment of small ships. FAQ: 1.What are the material advantages of this antenna compared with the early metal antenna? It is made of glass fiber reinforced plastic, which has natural corrosion resistance, no damage after 5000 hours of salt spray test, and its service life is more than 3 times longer than that of metal antenna. 2.What is the inconvenience in the installation of early metal antennas? The weight of early metal antennas generally exceeded 2kg, and the installation required additional reinforcement, which increased the difficulty and cost of installation. 3.What is the significance of 162MHz frequency band to nearshore communication? The 162MHz frequency band is a frequency band focusing on offshore communication, which can better meet the signal Transmission requirements in offshore scenes. 4.What problem is solved by raising the omnidirectional radiation angle to 360°? It solved the problem of the signal blind spot of the early metal antenna and ensured that there was no dead spot in the offshore communication. WELCOME TO CONTACT US!
