Model ADS-B-1090-12 1090MHz 12dBi Gain 
 

DME / TRANSPONDER ANTENNA

Design Features: ADS-B-1090-12 Fiberglass Omni-directional Collinear Antenna is rugged all weather model uses high class brass and 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and does not require any field tuning or adjustments. No ground plane is required to operate this antenna. The ADS-B-1090-12 antenna is an Omni-directional narrowband, higher performance, collinear dipole type phased array designed specifically for use as a ADS-B ground station antenna. All junctions are fully welded to prevent RF inter-modulation and antenna is completely protected within a high-tech ruggedized fiber glass radome to ensure survivability in the worst environments. The design of antenna allows controlling friction induced static, which could be created by wind and dust. The compact size of fiber glass collinear antenna allows easy handling and shipping.

Constructions: The ADS-B-1090-12 antenna is a center fed design which eliminates the distortion of the radiation pattern and ensures a true omni-directional horizontal pattern. The special stub matching is used for smooth VSWR and constant gain over the specified frequency band. The bandwidth of the ADS-B antenna is fairly narrow, which can help to eliminate inter-modulation problems from adjacent strong signals in urban areas. The ADS-B collinear antenna consist of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass tube. The antenna termination is enclosed at bottom of the antenna for complete weather protection. ADS-B antenna is strong enough to withstand an ice storm, and will also do well in a shoreline environmental conditions. The marine grade type 316 stainless steel mounting hardware is supplied with the antenna.
