The Diamond SE-100 Dual Band Marine Base Antenna is a professional-grade, high-integrity radiating asset precision-engineered to deliver elite signal tracking and long-range voice clarity across coastal installations and high-tier maritime base networks. Developed as a high-gain standalone vertical station, this premium fiberglass outer casing radiator provides absolute atmospheric shielding against saltwater spray, intense UV exposure, and persistent ambient moisture loops. It stands as an essential infrastructure component for harbor logistics offices, yacht fleet dispatch stations, marine scanners, and B2B telecommunications hardware distribution networks looking to source authentic, heavy-duty coastal radio antennas.<\/p>\n

The advanced internal phasing network features a high-performance collinear stack structured as a Type 2 x 5\/8 wavelength array at 144MHz and a 4 x 5\/8 wavelength array at 430MHz. This sophisticated internal layout concentrates radiation toward the horizon, achieving an exceptional gain profile of 6.0dBi on the 144MHz band and 8.0dBi on the 430MHz band. Operating cleanly across the frequency brackets of 144-146MHz (2m) and 430-440MHz (70cm), the antenna maintains a remarkably flat stationary (VSWR) curve of less than 1.5:1 into a system nominal impedance of 50 ohms, dropping the risks of power reflection loops or early transceiver front-end fatigue.<\/p>\n

Built to withstand severe offshore storms and structural movement, the heavy-duty fiberglass radome boasts an engineering-optimized nominal wind speed survival rating of 50m\/sec. The antenna handles a high maximum power throughput up to 150W (PEP), enabling its deployment alongside high-tier analog or digital VHF\/UHF base transceivers. Measuring a total physical length of 2.25m with a net weight of 1.5kg, the station links directly into coaxial arrays via a low-loss, gas-tight MJ terminal base. Included heavy-duty mounting hardware adapts cleanly to clamp onto a wide mast diameter variance from 25mm to 100mm, ensuring a flexible and secure structural fit for long-term field stability.<\/p>\n
