Marconi Aerial Outfit H-33-5500-01 Evaluation. Comparison of This Active Antenna with Two Previously Evaluated Active Antennas.

Abstract

The Marconi H-33-5500-01 antenna has significantly better noise figure and gain that either the Bayshore or DUK antenna; but, as with all active antennas, self-generated intermodulation product interference is likely where several nearby rf transmission occur simultaneously. Despite this susceptibility, this antenna is judged to be well engineered and properly designed and optimized for integration into hf receiving systems. Because of its small size, it could serve as a backup receiving antenna for hf and lower frequencies aboard Navy ships. Relationships are presented for apparent effective height, antenna noise power output, antenna noise figure, antenna gain, operating noise figure of a complete receiving system, and intermodulation intercept points, ratios, and product levels.
