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.

Instead of building eggbeaters, pick up a few of these:

You'll also need a pair of these:

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.
