摘要

The volume,Appendix B contains the measured radiation patterns of the Collins Model 237A-1A log-periodic structure,Doublet 28,Doublet 35,Collins Model 237H-1omnidirectional antenna,and Dixon Model OCM-68omnidirectional antenna. The text of this report,separately bound,presents descriptions of these antennas and of the measurements and data-reduction techniques. The measured patterns are grouped by antenna type,as listed above. All patterns for an antenna are grouped in order of increasing frequency. The horizontal polarization response pattern is presented first,followed by the vertical polarization response pattern (when both are available). In each case,the title block gives the antenna name,followed by the frequency and polarization.
