Abstract : NTENNA, AND A Spiral Log Periodic Antenna.Research and development technical rept.,D'Accardi,Richard J. ;Roswell,Edwin L. , III;ECOM-4085DA-1-H-662701-A-4481-H-662701-A-44806(*antennas, atmospheric sounding), antennas, spiral antennas, log periodic antennas, antenna radiation patterns, gain, standing wave ratios, high frequency, statistical analysis, ionosphereFull-scale measurements were made of the elevation-plane gain patterns of in-house constructed fixed and transportable versions of the delta antenna. These antennas are primarily vertically looking radiators intended for use in ionospheric sounding. Measured patterns and theoretical considerations are presented along with details of the construction of both delta antennas and the transportable delta erection system. Included for comparison is the Granger Associates Model 798 Logarithmic Periodic Spiral Antenna. (Author)
