GAIN OF DIRECTIVE ANTENNAS 65 certain calculated data similar to those contained in the present paper,and also experimental results obtained from tests on actual antennas ofvarious sizes and proportions. In the early part of the following discussion each antenna is con-sidered as a spherical source of waves which radiates equal power inall directions. Furthermore, it assumes that the current in each.
