It is sometimes necessary to reduce wind drag of an antenna. Within
limits, this can be done by making the cross-section of the elements
more oval rather than circular. If the wind load is always from the
same direction, the cross-section can conform to that of the struts
used on aircraft. The file STRUT.GIF gives offsets for the No. 1 Navy
strut, once widely used for low aircraft speeds.

If the wind is multi-directional, a reasonable reduction can be secured
by using this section from 0 to 50%, then a mirror image of this for
50-100 percent stations.

A problem with struts supported at one end, whether circular or streamlined,
is a tendancy to vibrate in the wind. A few pieces of rubber sheeting
about 1/16 by 3/4 by 6 inches can be fastened to the end of the strut to
absorb the vibrational energy.
