I have had an idea for some time: When you feed all these stacked antennas in phase you will have optimum radiation to the horizon (or just above). My idea is to add switchable delay lines to the hig
That would take some more sophisticated modeling software to see just how the delayed signals would interact with the ground reflections, they may not result in exactly what you want. In free space o

Seymour, W6CCY does this ... or at least did at one time. He had 2 I believe 6 element 20's spaced horizontally on two different towers and played with phasing (line length) to get them to work toget
It's been done. The 20m 4-stack at KC1XX can be switched by combination of antennas or by angle (when all four are selected.) Designed by K1GQ. 73, Dick WC1M 73, Dick WC1M SR From: "john@kk9a.com" <j
Hans, This idea of lobe steering or tilt is also used on commercial collinear / stacked dipole VHF/UHF verticals to apply an up-tilt or a down-tilt in the main lobe of the vertical to solve terrain/c

EZNEC using "real ground" says such a phasing system is not worth the time/effort. Remember, the ground reflection is always out of phase with the "real" antenna so any phase difference one applies t
