no symmetry.

It is obvious. But you can try to detect it.

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.

If electrons jump off from antennas it will be easy to measure in klystron:

The electron beam is collected after work. If starting beam is equal to
collected then no jump off.
