Report No. ARL-TN-0357
Authors: Christos E. Maragoudakis
Date/Pages: July 2009; 16 pages
Abstract: The effects of fiberglass poles of various cross-section and chemical composition on the radiation pattern of log-periodic antennas are presented in this document. The antennas were mounted with the poles parallel to the antenna boom and vertical to the radiating elements. Normalized antenna patterns depicting the effects of the poles on the radiation pattern in the 100 megahertz (MHz) to 1 gigahertz (GHz) frequency range are included in the appendix of this document.
