These high masts carry ihe upper insulatedends of an antenna of about 300 wires which descend in a coneto the lower masts, whence they are gathered into one conductorand led to the oj)erating house. The power contains twolarge and two small dynamos driven by a portable steam larger machines are intended to supply the continuous currentat 500 volts for a Poulsen arc. 284 RADIOTELEGRAPHY The condenser included in the oscillation circuit consists ofmetal plates hanging in air of a total capacity of -^^ of a micro-farad, and capable of being arranged in various ways. With thisapparatus it is estimated that a radiation of 10 to 15 kilowattswill be reached, employing a wave 3000 to 5000 metres inlength. 7. The Effect of Atmospheric Conditions and Te
