Back | Specifications | Optional Antenna Items

The dBs 580 Dual Beam Antenna is an Omni-Directional broadband, 10 element (upper antenna) and 10 element (lower antenna), higher performance, collinear dipole phased array designed specifically for use as an Automatic Dependent Surveillance-Broadcast (ADS-B) Antenna. The upper antenna is designed for use as a Mode-S Extended Squitter (1090 ES). The lower antenna is designed for use as a Universal Access Tranceiver (978 UAT). The isolation between the two antennas is >30 dBi.

Both Antennas exhibit 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 Dual Beam 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 Ω of less than 2.0:1.

This Dual Beam Antenna provides vertically polarized, omni-directional coverage with both of the main beams of radiation uptilted to minimize the effects of ground reflections.

The array is enclosed and effectively weatherproofed within a lightweight, small diameter filament wound and ground smooth fiberglass tapered 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 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 stainless steel cover) and plate adapter are available option items.

The Model dBs 580 Dual Beam ADS-B Antenna has been designed for ruggedness, lightweight, minimum size, long life and in accordance with FAA-E-2754 and FAA-E-2100. It also exceeds the requirements of the UK CAA specification.

dBs 580 Dual Beam Antenna with Marine Option (P/N: 580300-120): The dBs 580 Dual Beam Marine Version antenna is an optional upgrade. 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.
