The dBs 5100A-HS de-icing antenna is an omni-directional broadband, 10 element, higher performance, collinear dipole phased array designed specifically for use as a Distance Measuring Equipment (DME) antenna.
The antenna comes with a built-in automatic de-icing system to prevent the buildup of ice in harsh weather conditions. The automatic detection system accomplishes this by turning the heated radome option on and off for intervals of one hour as long as icing conditions exist. When icing conditions do not exist, the heated radome option is automatically turned off. The heater input is 240VAC using an MS3114E8-4P circular mil connector interface.
The antenna includes a ruggedized high strength radome and base capable of surviving 180 mph wind loads.
This antenna 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 the 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 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.
This antenna comes standard with an included dBs Pipe Adapter that allows the antenna to mount to a 4″ O.D. pipe. The antenna also comes standard with a dBs Marine Option Stainless Steel Cover for the Pipe Adapter.
Lightning rod kit, obstruction light, and plate adapter are available option items.
The model dBs 5100A-HS-ICE DME 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.
