DME / TRANSPONDER ANTENNA

Design Features: Transponder antenna is rugged all weather model uses ultra corrosion resistant beryllium copper with chromium finish and does not require any field tuning or adjustments. This transponder antenna is an Omni-directional broadband, higher performance, quarter wave top loaded stub monopole type antenna designed specifically for use in aircraft for transponder application. The antenna does not use any junction to prevent RF inter-modulation and is completely protected within a high-tech ruggedized fiber glass radome to ensure survivability in the worst environments. The compact size of transponder antenna allows easy handling and shipping.

Constructions: Antenna radiator is mechanically captivated and is machined from solid brass for impact resistance. Contact points are made from beryllium copper with gold finish. Metallic parts are plated with bright chromium for corrosion protection. A single 0.625 (16mm) diameter hole is required to mount the antenna. This transponder antenna is a center fed design which eliminates the distortion of the radiation pattern and ensures a true omni-directional horizontal pattern. The special top loaded quarter wave stub monopole matching is used for smooth VSWR and constant gain over the entire frequency band. The antenna termination is enclosed at bottom of the antenna for complete weather protection.
