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.
