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.

Please don't use eggbeaters. That is all.

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!

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.

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!

Oh, that's right, you're the dude who's still butt-hurt because I called people out about bullying new users who ask about tripods.
You're the dude who assumed that since you never heard me TX that meant I wasn't operating at all.
You're the dude whose reading comprehension is lacking.
And you seem to be the dude who thinks that if you know one aspect of operating you know them all and can't ever admit ignorance.
Please don't bother to respond to the thread any more -- I know I can't trust any advice you might give, out of only the best of intentions, because you make too many faulty assumptions.

OK Devin since you want to do this in public ---
Yes, I'm one of the guys (AL6D is the other) you sent an out of thread reply to back on April 24th scolding us like a school marm for not just accepting people who are causing deliberate interference. You then proceeded to use a bunch of snowflake words like "ableism" at me and Gabe. I promptly told you to go to hell with your preaching, and I'll tell you again now in public.
Back on topic, here's the low-down - if you're not actually making contacts, then you're not operating. You're SWLing. Any old joe with an SDR and a coat hanger can listen, and they might even hear something from time to time, that is a far cry from being a successful op. I'm not going to bother telling you about the success I've had on Satellites (you can figure that out yourself if you care too) but rest assured I do have a clue. Interestingly, you have made 36 replies to this list since 2016 (based on a quick search) and have no doubt seen countless thread about Omni's, tripods, and Eggbeaters. Yet you have never made a QSO, and still come in here offering incorrect advice to others, all the while playing the family oh so poor card, to explain why you would want to build a sub-par setup and cause deliberate interference on the current LEO fleet. You sir are a genuine troll of the highest order, I only replied in kind with my dummy load post suggestion.
You can reply to this thread if you like - cause I'm just a guy and don't claim to have any power over other people's speech. I please do request though that you don't ever get on the birds, cause you're obviously incapable of the basic functions necessary to operate.

I’ll second this post and state that a directional antenna, either Yagi or LPDA will always work best for satellites.

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!

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.

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.

In all seriousness, how do you get that I’m promoting “accepting people who are causing deliberate interference?” Notice that I’ve taken very seriously every single operator on this list who replied to my query today with details about how eggbeaters’ reception characteristics make them more likely for operators to not hear themselves at low elevations. As a result, if I do end up making an eggbeater, it will be a receive-only antenna as a learning experience for me and my son.
I see pictures all over various AMSAT-affiliated forums of people who have their Alaskas on counter-weighted tripods, or people who have home-made antennas on tripods, who are actively using the sats. When I first joined this list and started asking about tripods, all of the advice I received was basically “that’s more weight” and “you just have to learn how to point it manually” and bunch of variations on those themes. Nobody said “tripods cause interference” or “the only people who use tripods are trying to cause interference.”
What is mechanically and electrically different (other than the motors) from an antenna on a tripod vs. an antenna on a rotator (SatNogs, Arduino-based SatTracker, etc.)? How does the former cause more interference than the latter? There’s nothing in the literature that I can find that addresses that topic and I really DO want to DTRT.
I’m clearly missing something here, because I’ve not seen any explanation of how using a tripod *causes increased interference*. Not once since I signed on. You’re the only person I’ve seen make that correlation. You clearly know something the rest of us don’t. *Please share it so the rest of us can learn.*
If you’d take the time to explain instead of just throwing the baby out with the bathwater, the community would benefit. You clearly have a lot of experience and knowledge to offer.
Also, where in my “36 replies to this list” have I offered incorrect advice? If I’m wrong, I would like to know, so that 1) I learn to do better and 2) I don’t repeat the same incorrect advice.

OK Devin since you want to do this in public ---
Yes, I'm one of the guys (AL6D is the other) you sent an out of thread reply to back on April 24th scolding us like a school marm for not just accepting people who are causing deliberate interference. You then proceeded to use a bunch of snowflake words like "ableism" at me and Gabe. I promptly told you to go to hell with your preaching, and I'll tell you again now in public.
Back on topic, here's the low-down - if you're not actually making contacts, then you're not operating. You're SWLing. Any old joe with an SDR and a coat hanger can listen, and they might even hear something from time to time, that is a far cry from being a successful op. I'm not going to bother telling you about the success I've had on Satellites (you can figure that out yourself if you care too) but rest assured I do have a clue. Interestingly, you have made 36 replies to this list since 2016 (based on a quick search) and have no doubt seen countless thread about Omni's, tripods, and Eggbeaters. Yet you have never made a QSO, and still come in here offering incorrect advice to others, all the while playing the family oh so poor card, to explain why you would want to build a sub-par setup and cause deliberate interference on the current LEO fleet. You sir are a genuine troll of the highest order, I only replied in kind with my dummy load post suggestion.
You can reply to this thread if you like - cause I'm just a guy and don't claim to have any power over other people's speech. I please do request though that you don't ever get on the birds, cause you're obviously incapable of the basic functions necessary to operate.

I got a good chuckle out of KG5CCI's link to the MFJ Dummy Loads. Quite a few years back, I picked up a pair of the M2 Eggbeaters at a Hamfest for $150. I put them up with some 9913 and found that they were very close to being Dummy Loads in the sky. That was probably why the guy was selling them so cheap. They were sold again a couple years ago at Dayton for the same price. Lesson learned. I always thought the concept was very good, but the results were very disappointing. That was before the excellent performing SATs we have up there now. Maybe they would have moderate success now, but I wouldn't get my hopes up. My suggestion would be to get/build a couple small Yagis and put them on a mast several feet apart with the 70cm above and the 2M below with one vertical and one horizontal polarized. Tilt them up 15-20 degrees and a cheap TV Rotor is all you need. The tilting can be done by fashioning a mast-to-boom plate drilled for the desired angle for each antenna. Or, you could merely bend the mast that small amount. This should give you reasonable success until you decide you have the experience to get more sophisticated and will not have spent a bunch of money initially. GL/73, Bob K8BL (AMSAT #6593 since 1979)

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.

Psat is one of the weakest satellites up there. It is only 0.25W AND that is FM packet. So when you compare that to a 0.1W linear downlink, which is on al the time, the average power of PSAT is only 0.025w. But it was the only transmitter we had at the time. PSAT2 will be 1.5W or about 8 dB stronger.

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!

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.

Eggbeaters have been discussed hundreds of times on the BB...just do a little research and you'll find that they're terrible for working sats.

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-...
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)

A cheap yagi is probably the best thing to get started with an HT.
http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf
The most effective omni antennas are probably parasitic lindenblads, but omnis are always a compromise, especially if you are not in a very low noise area.

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

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?

Arrow II antenna. In your hand... Any yagi. In your hand... I operate portable in Southeast Alaska, which as far as weather is like Western Washington but colder, wetter, and in general more severe. And I use an Arrow, in my hands, winter, summer, whatever...

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.

Hi Devin,
A nice & clear calculation and construction article from ON6JC/LW3HAZ on eggbeaters is at:

Hope is useful,

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.

I bought a set of egg beaters recently and they seem ok for anything higher than 20 degrees. I'm looking to build a moxon variation http://www.oocities.org/w9bci/VHFUHFSatelite.pdf at some point when I have some free time.

I am happy with the moxon - uhf pretty small and wiring can be challenging with the phasing and matching lines. My uhf has a mast mount preamp, vhf just 30 ft coax and rtl-sdr at Max gain. Could be better but all I want to invest at first. QFH are highly recommended and you can see then on old videos of the lunar lander :). Satnogs stations 142 and 216.
