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

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.

Not to mention the blockage from the feed horn. [g]
