Default 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.
