Ahertzian dipole is to be used by an radio amateur at 30 mhz. the fcc regulations indicate that the radiated field at a distance 2/27 (you can assume this distance is in the far field) and at a direction of maximum intensity must be less than 15 2 uv/m a) what is the average power flow density in a direction of maximum intensity if the electric field is equal to 15 2 uv/m? b) what is maximum time-average radiated power that the user may use with the antenna?
