In fact, in real world and with real measurement devices, the units are not related to "instantaneous voltages" and even lesser "voltages seen at the antenna". Any form of antenna may deliver different voltages. Is it some Yagi antenna? Or is the active element a closed loop? Both forms would

Dear All, Changing only FFT size of the freq sink block during simulation drops signal power drastically, screenshots are given in the attachments. I am providing the pulse burst from the vector source as 6144 points (6 ones and the rest of the points are zero). Since FFT sink blocks show the
