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.

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.

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!

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.

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:
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!

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.
