There is someone on the AMSAT-NA Facebook group who built an egg beater setup with preamps at the mast who seems to be having success. He seems to be really good at fashioning metal and the results look impressive from a purely mechanical and aesthetic perspective.
Does anyone remember who I'm talking about?
If we figure it out you could ask him for info on his setup and experience.

I have an Elk for my D72A and that works fine when the weather cooperates. Note below where I say I *replaced* the Baofengs - they're no longer in play, for anyone named David Swanson who cares to take a swipe at me for those.
For those times when it doesn't (I live in Western Washington, so that's quite a bit) I'm building something to mount on top of the house to use with my Yaesu 857D until I can afford a rotator + M2 LEO pack or something similar. We just bought our house, have two kids in college, and are actively trying to get out of debt within the next year, so just going and buying a ton of expensive hardware is not in the budget at this time. Otherwise I would be asking about towers. :)
I understand that the eggbeaters have their flaws, but I've read claims that the Eggbeater-II design (which is more Moxon-like from what I understand) offers better gain at the horizon than either the pure eggbeater or Moxon. Is this not the case?

Hi Devin, frankly the 'eggbeater' days have come and gone in the
efficiency
dept.
Attached is an article from QST on the Moxon turnstile, a much better
option.
Better than that is an Elk on a 'rat shack rotor at 15-20 deg fixed el.
If interested, I can send you my files direct on either

Greetings, programs!
I'm looking to work with my son (who will be studying to get his
Technician
license later this month) on building a UHF/VHF pair of eggbeater
antennas.
I've found a few papers online, but does anyone have a good reference to
a
detailed design?
Does the ARRL Antenna book latest edition have any significant coverage
of
eggbeaters at all? I have an older version that has nothing.
Also, most of the designs I see are for a single band. If you're
deploying a pair
for satellite operations, do you simply attach them through a duplexer? I have a Diamond MX-72N that I picked up a while ago for using with dual Baofengs, but it's been sitting in my drawer since I picked up my
TH-D72A.
It has a 1.6~150MHz lead and a 350~460MHz lead.
Thanks in advance for any pointers you might have.
