What happens if you pipe the output of one radio in to 2 amps?

There is another potential problem if feeding two amps to two antennas
that are reasonably close: RF from one antenna is induced into the other
antenna, gets fed into the amp and causes some interference (mixing ?)
that shows up as a raspy signal.
Tried it, and heard it on another station attempting the same setup.
It seems that it would be easier to control the phasing at the input of
the PAs, but the above effect messes it up, unless antennas are widely
separated and they do not "feed" each other setup.
So, it appears that it is better to use one bigger amp and use proper
phasing to feed the two or more antennas.
Well, the expert, or should I say, the new GURU, has spoken. He seems to
know all about this complex subject.
Aaaah, here chimes in another W8JI worshipper, who can not read posting,
understand it and reply intelligently, but resorting to snotty, personal,
pathetic remarks. You may have noticed that I do not take crap and
respond in kind.
I know I will never try this again, as my previous efforts, which seemed
to work, could not possibly have done so. Obviously Wilkenson hybrids
are useless, likewise any ring hybrids, and all other methods of
splitting/combining a transmitter feed.
READ IT AGAIN carefully, I have not say that "Wilkenson" (learn spelling)

Thank you for showing your feathers and displaying your depth!
Your picture would look pretier if you engaged in technical, civil
discussions, rather than that "W8JI thing".

As far as replying in kind, I've been reading your posts for quite a
while, and I haven't noticed that you withhold any criticisms.
If the only errors you made were typos, this crowd wouldn't have a problem
with you.
And I know when I am out of my depth, and to keep my mouth firmly shut, as
apparently you do not.

Typical response. Just read what happened in this thread.
Look at what I wrote, look at what you responded.
I am not criticizing, I respond to crap and personal attacks in kind, not
very nice, but I do not need to put up with snotty remarks and personal BS.
Looks like hurlers don't like when one responds in kind.
If discussion is about technical matters, I provide help where I can or feel
like. If jerk doesn't like it and comes riding high horse, then I get on my
horse too, which happened with W8JI (we go way back) and now with you.
I provided my opinion on 2 PAs to 2 ANTs, you twisted it and snapped GURU
crap on it, Richard Clark was right behind you. I hate to see you when you
are out of your depth. Now you come on with lecture about "crowd having
problem with me"?
You discuss technical matters in a civil way, I respond in kind, you pull
out snotty crap, and I don't take it. Mark it down and next time if you want
do the technical exchange I am open for dialog.
What you want me to do to be "nice"? Accept the "truth" that current along
the loading coil is ALWAYS the same, that shield IS the antenna, that
electrostatic shield can't possibly work, that antenna is not an antenna?
Where I come from, we fight for truth and if needed give life for it. If you
want me to bow to false teachings, or to take crap, look somewhere else.
So you want to try to be nice and discuss the problems with intermods
between two PAs feeding two antennas or play W8JI? I can also engage on
Wilkinson's hybrids, I use them.
Let's stay with the subjects of this NG and keep the crap for the toilets.
