The dBs 5100A is an omni-directional broadband, 10 element, higher performance, collinear dipole phased array, designed specifically for use as an Automatic Dependent Surveillance-Broadcast (ADS-B) antenna. It exhibits very low side lobe levels and negative angle radiation (minimizes multipath). The above-the-horizon null-filled pattern minimizes the radiated cone of silence. The antenna handles input power to 5,000 watts at standard ADS-B pulse duty cycle and operates over its entire frequency range with an input VSWR at 50 ohms of less than 2.0:1. This antenna provides vertically polarized, omni-directional coverage with the main beam of radiation tilted upward to minimize the effects of ground reflections. The array has two integral monitor probes which constantly sample the RF signal delivered to the antenna. The array is enclosed and effectively weatherproofed within a lightweight, small diameter, filament wound, and ground smooth fiberglass radome, for prolonged trouble-free use under severe environmental conditions. Mounting is made by means of an integral base flange with 6 each mounting bolt holes. All RF input/output ports are Type N receptacles. Obstruction light power is fed through the array and a provision is made for mounting an obstruction light and/or arrestor at the top of the array. Lightning rod kit, obstruction light, pipe adapter (with or without cover), and plate adapter are available option items. The model dBs 5100A ADS-B antenna has been designed for ruggedness, lightweight, minimum size, long life, and in accordance with FAA-E-2754 and FAA-G- 2100. It also exceeds the requirements of the UK CAA specification. Over 5,000 antennas delivered worldwide. dBs 5100A with Marine Option (P/N: 500300-120): The dBs 5100A Marine Version antenna is an optional upgrade as well. The RF transmission assembly is completely sealed and weatherproofed to protect in harsh environments such as salt water, extreme humidity, wind, sand, snow, and ice. Contact our factory for more details.
