VALUE OF INSULATION.
The ’ polo supports or guy wires attached to the aerial have to be watched, and where a number of steel wires ai'e employed they must be broken at top and, bottom with insulators. Some say, “ Why the necessity to insulate at both top and bottom! " _ Well, with an iron or steel pole any. induced currents will flow upward through the wire and down the central pole if only insulators are used at the botttom of each any wire. More attention is paid to this sti.y wire insulation on a transmitting aerial than on one employed for reception only. It should always be remembered when erecting_ the aerial installation to sink a foot, which may consist of several bricks or a piece of totara .wood on which the aerial pole stands. Otherwise after one or two windy nights the guy wires will be found to be getting loose, due to the pole working further into the ground. Once a guy wire becomes loose the polo is in great danger of falling during a storm*
