510A-HS Omni-Directional High Strength Antenna

Part Number: 510300-103

dBs 510A-HS

The dBs 510A-HS is an 8 element, high performance, full service, all band, omni-directional, Distance Measuring Equipment (DME) antenna.

This omni-directional antenna has 8 active elements and other components, which produce high main lobe and horizon gain with wide beam width. The antenna handles input power to 5,000 Watts at the standard DME pulse duty cycle and operates over its entire frequency range with an input VSWR at 50 Ω of less than 2:1.

This antenna provides vertically polarized, omni-directional coverage with the main beam of radiation up tilted 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 dBs 510A-HS antenna is designed for high wind environments. The mounting base and Radome have been ruggedized to withstand, without damage, wind gusts up to 180 mph.

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. Lightning rod kit, obstruction light, pipe adapter (with or without cover), and plate adapter are available option items.

The model dBs 510A-HS 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.

dBs 510A-HS with Marine Option: The dBs 510A Marine Version is an optional upgrade from the base model. 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.
