Back | Specifications | Optional Antenna Items

The dBs 540 is an Omni-Directional broadband, 16 element, very high gain (>12dBi), 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 at all ADS-B, L-Band frequency ranges with an input VSWR at 50 Ω of less than 2.0:1.

This antenna provides vertically polarized, Omni-Directional coverage with main beam of radiation up-tilted 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 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 lightning arrestor at the top of the array. See picture below.

Lightning rod kit, obstruction light, pipe adapter (with or without stainless steel cover) and plate adapter (wall mount) are available option tems.

The Model dBs 540 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 540 with Marine Option (P/N: 540300-120): The dBs 540 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.
