I was wondering what is the highest gain hf antenna thats operational
anywhere in the world? Secondly what is the gain.

Available from my web page below, this antenna models
out to have 24 dBi omnidirectional gain. :-)

It is most likely the huge dish in Arecibo, Puerto Rico.
Close by would be the HARP system in Alaska.
Then the curtain arrays used by broadcast stations.
Then the Rhombics, then the rest.

Arecibo ISN"T an "HF" antenna.........

Just for the heck of it , I did a little internet check on Arecibo and found
the following info;
""Full operation of the facility ideally requires three frequency bands,
near 3.175, 5.1, and 8.175 mhz."

IT IS!
It has been used by hams as low as 3.5 MHz band.

Seems like Arecibo might have around 36dB gain at 28MHz where it is a
28 wavelength dish, at least according to scaling numbers I found on a
random webpage.

Not bad. Seems that a 3.5 wavelength dish (3.5MHz Arecibo) still has a
bit of gain too. 15dB?

I wish I had 15dBd gain on 3.5MHz... don't exactly want it straight up,
though.

That's OK. Just hoist up one mountain, lower the other, and rotate
the whole dish/valley onto its side. Paul Bunyan would have thought
nothing of it.

i don't understand what this means? that they mix these freq's to get
their usual super high seti freq xxxghz or what ever
