dBs 560 SSR

The dBs 560 is an omni-directional broadband, 12 element, Secondary Surveillance Radar (SSR) side lobe suppression, collinear dipole phased array designed specifically for use with the ASR-3 Radar. 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 and optimizes the side lobe suppression performance of the radar system. The antenna handles input power to 4,000 watts at the standard SSR 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 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.
