A COUNTERPOISE

An, insulated counterpoise will work very well in place of the ground on a receiving set. In locations where the earth is sandy or dry and a good ground connection cannot be obtained, a counter poise is superior to a regular ground connection. A counterpoise is conestructed exactly like an acrial; and igs suspended directly beneath the aerial and near to the earth, It is connected to the ground binding post on the receiving set in the regular manner. Both the counterpoise and the lead to it should be well insulated from the ground, As in the aerial and lead-in, it is best to use enamel copper wire, about No 12, in the counterpoise. A receiving set using an insulated counter poise instead of a regular ground connection is not so likely to pick up inter ference fromm electric light lines, vacuur cleaners, door bells, and telephones. ~
