Waterproofing Aerial Ropes

a oe An Effective Method ALTHOUGH the electrical and insulating efficiency of the aerial should naturally receive first attention, it is not wise to forget all about the other components of the aerial system. For instance, aerial guy ropes, after they have been in use for a season or two, often show signs of deterioration owing to their continual exposure to inclement weather. An effective waterproofing preparation is as follows :-- Dissolve two pounds of ordinary alum in a -bucket of boiling water. Allow the water to cool, and then steep the aerial ropes in this liquid for two days. After the lapse of this time remove the rope from the alum solution,, and, without any rinsing, hang it up to dry. . By this simple procedure the rope will be rendered waterproof for at least 2 year. The process is an efficient one; its cost is almost -negligible, and it is clean to earry out. The process may also be applied to the waterproofing of fabrics which are used to cover up any articles or instruments of electrical and radio use which may have a temporary or a permanent position out of doors.
