Discussion on “overhead electrolysis and porcelain strain insulators,” (S. L. Foster), San Francisco, Cal., Sept. 17, 1915. (see proceedings for August, 1915)

L. W. Webb: This wire (samples of copper-clad wire were exhibited) has been used on radio antenna on shipboard, and has proved entirely unsatisfactory for this use. It lasts from three months to a year maximum, and often not as long as three months. When once installed and not taken down it lasts the maximum length of time; but if disturbed after being installed the individual strands are found to be broken throughout the entire length, and the least twist or kink breaks the completed wire entirely. Where installed close to the smokestacks on vessels the escaping gases cause rapid deterioration, and cases have been noted where the wire lasted only about two or three weeks.
