Getting Ready to Test. Whenever possible you want to adjust the antenna in place on it's mounting structure. In this way you are taking the structure and other unavoidable local objects into consideration. 160 and 80 Meter Antennas . for the Declining Solar Cycle. Vertical polarization on 160 meters.

The figures show the solar magnetic field from May 1976 to the present, covering nearly 4 solar cycles. Cycle 24 was weak.. (Top): The. mean field. (MF) shows the Sun viewed as a star, where all magnetic signals from the visible disk are integrated. The MF typically peaks during solar maximum or a little later. Cycle 24 was relatively weak, but the peak was comparable to or larger than recent cycles and was reached 2015 as a consequence of the development of a large low-latitude unipolar region over several months. . .
