Back | Specifications | Optional Antenna Items

The dBs 5100A-D/180 is an Uni-directional broadband, 10 element, higher performance, collinear dipole phased array designed specifically for use as a automatic dependent surveillance broadcast (DME) 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 DME pulse duty cycle and operates over its entire frequency range with an input VSWR at 50 Ω of less than 2.5:1.

This antenna provides vertically polarized, Uni-Directional coverage with main beam of radiation uptilted to minimize the effects of ground reflections. The horizontal HPBW is a nominal 180. 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 6.25" O.D. filament wound ground smooth fiberglass radome for prolonged trouble free use under severe environmental conditions. The uni-directional radiation pattern is produced by a full length pattern shaping element within the radome. 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 provision is made for mounting an obstruction light and/or lightning 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-D DME antenna has been designed for ruggedness, lightweight, minimum size, long life and in accordance with FAA-E-2754 and FAA-E-2100. Exceeds the requirements of the UK CAA specification.

dBs 5100A-D/180 with Marine Option (P/N: 500300-130): The dBs 5100A-D/180 Marine Version antenna is an optional upgrade as well. The RF Transmission assembly is completely sealed and weather proofed to protect in harsh environments such as salt water, extreme humidity, wind, sand, snow and ice.
