Tower and Antenna Wind Loading as a Function of Height
www.va3cco.comFunction of Tower Height The wind load on the tower proper is determined by applying the total horizontal wind force on each tower section at the center of each of the sections. So, referring to Fig 1 and starting with the lowest section, the distances from the base to the mid-points of the tower sections as a func-tion of tower overlap become ...
40 Meter Mini-MOXON Beam Antenna At W7XA - IW5EDI
www.iw5edi.comInductive loading is easiest and most practical. • On a MOXON, the parallel elements are well supported or made from some kind of tubing and loading can be easily implemented. Consider that most of the radiation on an antenna is from the high current end of the elements (the end closest to the feedpoint in a dipole or ¼ wave vertical).
