The radiation is in form of the damped wave:

? 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.
