John:
Joe Reisert W1JR published an interlaced design for 17/24M in the Feb 2022
QST. Maybe you can scale it for 15/20M.

Momobeam have a 20/15 duobander with separate feeds and 4el per band. I have
one here, but it's not built yet. I'll see if I can find the instruction manual
which at least would give you some dimensions to work with. LMK if that would
help.

Subject: [TowerTalk] Dual Band OWA Design
I just completed a big antenna project on my 150 Rohn 65g tower. I refurbished
or replaced every antenna on the tower, I added a couple of rotators and moved
things around a little. I still have a low unused ring rotor installed and I
would like to eventually add a smaller (maybe 3el per
band) dual band 15m, 20m Yagi. I enjoying homebrewing antenna and have plenty
of aluminum. I could use some design suggestions for creating a beam with
separate feedlines, preferably OWA. I have EZNEC and autoEZ but I have limited
experience with the latter. I have been unable to find any 15m/20m interlaced
Yagi model examples to get started with. I appreciate any assistance.
Thanks,
John KK9A
