AN AERIAL FOR SHORT WAVES

Fading on the short waves is often noticed because listeners who tune in on the short-wave stations couple their sets to their regular broadcast aerial, which is usually of the long horizontal type. While short waves may fade inherently to some extent, much of this is due to the receiving aerial used. A vertical aerial should be used in order to eliminate much of the fading now experienced on these waves. Incidentally, the vertical aerial makes for a much neater job on any house, and in many instances simplifies the erection, since the long stretch of the ordinary flat top demands two points of suspension well apart, with resultant guying. When erecting such an aerial it should bo kept a couple of feet away from the structure. In order to obtain this condition it may slope a bit upward and then connect to a short cross wire running from tree to house, care being taken, however, that the vertical portion be completely insulated from the flat portion, which merely becomes a supporting wire for the vertical aerial. This typo of aerial is practically the lead-in.
