The Spreaders.--Any kind of strong sticks will, of course, do for the spreaders, but it gives a fellow a lot of pleasure to have a good-looking aerial as well as a good working one. I? Fig. 131.--The Spreader For The Ends. Four spreaders are needed, one at each end of the aerial, one in the middle to keep the wires apart, and a short one for the leading-in wires.
