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.
