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.

feedpoint is 50 ohms, and 99% efficient... how much now?

i have worked with klystrons... the current in equals the current out,
all electrons are accounted for.

And peak voltage at the end?

So in your area the field emission do not work.

i don't have any electrons jumping off my antennas... but i still talk
around the world. your theory must be wrong.

Field emission is voltage dependent. What is the voltage peaks on the end of
your antennas.
Even if they are symmetric the emission is different for negative/positive
voltage. The negative emission is stronger.

Put on CB antenna the cathode ray trap (vacuum tube) and measure the
anticathode to ground current.

how can it be voltage dependent if it is necessary for the rf signal?
do qrp signals that only generate 1v on the tip of the antenna not
generate rf waves and propagate??

oh yeah, riddle me this... infra-red light is another form of
electromagnetic energy which can be picked up from the heat of your
body by an IR camera... since your body is radiating em waves
continuously why aren't you always charged??

I am emitting (loss) electrons and I am always positively charged. See:

It seams that in your area the physics laws do not work.

triboelectric charging can result in you being positive or negative...
and is not related to IR radiation you are emitting all the time. lay
still flat on the ground and you will not be triboelectrically
charged, but you will be constantly radiating IR radiation.

Excellent thinking. If I am laying on the ground I constantly pump electrons
from the ground into the air without being charged. Exactly like your
transmitting antennas connected with the ground or chassis. Without
connection to ground they becomes positively charged.

Are you able to measure the static voltage of a human skin?
