Johan, ON4ANT, has just sent me an update on his forward stagger array of
Yagis on a single mast for 20-10. The new modeled specs--which I
confirmed on a different program--are min free space gains of 8.2 on 20,
17; 8.7 on 15, 9.6 on 12, and 9.8 on 10 meters. Still only 14 elements.
Feed Zs in the 20s/30s on all bands for standard matching techniques.
So I updated the former Two Forward Stagger. . .to Three Forward Stagger
Designs in the upper HF collection.
Did I forget to note that it only takes a 60' boom? I hope there is a
useful design idea or two for someone there.
