Since 1974, many Wisconsin Test Facility (WTF) phasing anomalies have been observed. Among these anomalies are (a) ψ° phasing does not equal (360° − ψ°) phasing, contrary to the normal behavior of crossed dipoles; (b) the maximum field strength at any single receiving location does not occur when ψ = 0 or 180°; (c) the WTF antenna phasing shift appears to be −20° to −30°; (d) the WTF effective dipole moment does not appear to be independent of ψ; and (e)the WTF antenna phasing shift appears to be a function of azimuth angle. By a combination of near‐field and far‐field measurements, we have determined empirically a new WTF pattern factor that quantitatively describes these anomalies.
