WIRE FOR AERIALS.

Which is the best kind of wire for a broadcast receiving aerial? Opinions vary a little on this point. An American authority says: ‘‘While the actual size would depend upon the span, No.. 14 B & S hard-drawn copper wire will auswer for any spans up to 125ft. Above this, it would be safer to use No. 12 wire. Phosphor bronze wire is used for long spans but the cost is considerably higher. The solid wire, despite theory, will not give an appreciably higher resistance (which is wndesirable) than stranded wire. From tests on loop aerials, it. has been found that the heavier the wire the better the results’ obtained. Care should be taken that all the wires should be as well insulated as possible, both from the frame of the loop and other objects."
