Results of the Wisconsin Test Facility Phasing Anomaly Investigations.

Abstract

Since 1974, many Wisconsin Test Facility (WTF) phasing anomalies have been observed. Among these anomalies are (1) psi deg phasing does not equal (360 deg - psi deg), contrary to the normal behavior of crossed dipoles; (2) the maximum field strength at any single receiving location is not when psi = 0 deg or 180 deg; (3) the WTF antenna phasing shift appears to be -20 deg to -30 deg; (4) the WTF effective dipole moment does not appear to be independent of psi; and (5) the WTF antenna phasing shift appears to be a function of azimuth angle. By a combination of nearfield and farfield measurements, we have empirically determined a new WTF pattern factor that quantitatively explains these anomalies.
