In damped waves each amplitude is smaller than the previous. So in one cycle no symmetry. It is obvious. But you can try to detect it. S* can't detect it here, my waves look like perfectly symmetric sine waves and i can not measure dc on antenna. *how much dc should i have with 1000w at 14mhz? I do not know. It is peak voltage and efficiency dependent. feedpoint is 50 ohms, and 99% efficient... how much now? If electrons jump off from antennas it will be easy to measure in klystron:http://en.wikipedia.org/wiki/File:Klystron.enp.gif The electron beam is collected after work. If starting beam is equal to collected then no jump off. S* i have worked with klystrons... the current in equals the current out, all electrons are accounted for. |
