Instead of building eggbeaters, pick up a few of these:
http://www.mfjenterprises.com/Product.php?productid=MFJ-261
You'll also need a pair of these:
https://www.amazon.com/Coaxial-Cable-Female-SO239-PL259/dp/B00KQHH7VC
Hook those into your baofengs and you'll be just as effective on the
Satellites as you would with some homemade 'beaters.
Good luck! 73!

Maybe we do it like used to, manually. Tune & listen. Worked for years.
Instataneous gratification has become the norm and complaints are increasing.

Ah, yes, rather than maybe educate someone let's just berate them and
functionally call them an idiot.
Eggbeaters have a bad rap because they don't necessarily hear well. You may
be making it into the bird but not hearing yourself, so you keep tuning
around and calling trying to find yourself only to be deaf-ly QRMing other
stations. I have no experience with them, but that's what I've heard.

Have the magnetic poles reversed or something? A guy asks for help with
a legitimate question and all he gets is comedians? AMSAT is better than
that.
I do not know enough to help, but there are folks out there who do.

That erases the fun factor and feeling of accomplishment. Plus parents and
their children working together on a project with resulting success is very
powerful, and important.

Hello Devin,
Notwithstanding the unhelpful, verging on rude, comments from others on
this list, here's a good video on the performance achieved by AA4KN with
the Texas Potato Masher.
https://www.facebook.com/153679794647788/videos/texas-potato-masher-antenna-ev
aluation/118367264891484/
How to build:
http://wb5rmg.somenet.net/k5oe/Texas_Potato_Masher_2.html
Ideally, you'd benefit from a LNA _at the antenna_, to set the system
noise figure early. This becomes very important if you have any length
of coax between the antenna and the rig.
I'm glad you and your son are building parts of your station! That's
something to be said in these times of buying your way into the hobby.
See what can be done on a shoestring budget and learn while you experiment!
(and I love the Tron reference)
73,

Hi Sean!
I don't recall seeing any name calling here until your post, I genuinely
want to make sure the author of this thread who has sent numerous emails to
this list explaining how to operate gets the best tips in regards to their
planned build. I'm actually in the process of building the setup I
recommended and will plan on doing a demo for folks sometime here soon,
stay tuned!

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

Subject: [amsat-bb] ARRL Antenna book, eggbeater antenna designs
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.

Resending this to the list, instead of just to Sean. Sorry, Sean!
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?
