TECHNICAL EVALUATION A BROAD-BAND OMNIDIRECTIONAL ANTENNA

摘要

This report describes a broad-band unidirectional antenna which operates in the frequency range of 5 to 10 kn. In azimuth it has a circularity of ± 2db. In the vertical plane its coverage is approximately cosecant-squared (csc2), and maximum beam is attained at 22 above the horizon. VSWR is less than 2 in the 5- to 10-kmic range.
