Thanks for the reply Homer,

I've been speculating about this "Super Starduster" EDZ for some time now.

Ever since I started dying my hair grey to get the senior citizen discounts, I don't look forward to multiple trips up & down my tower anymore. Must be chemicals in that grey hair dye that saps my strength & resolve.

I just find it interesting that I can't find ANY reference to anyone building a vertical EDZ for any band. It would seem that a "real" 3 Dbd gain would be so attractive to try it.

You would think that someone would post even a FAILED attempt. Maybe I will be the first to post about such a failure.

I know that computer modeling can only approximate performance in a real world application but I wonder if the modeling can give any insight. Maybe someone handy with the program will develop enough interest to try to model it. I expect the vertical feed modification and metal mast & coax feedline interaction may be difficult for the software or the guy entering the data.

At this point I think I may build a vertical wire EDZ on my wooden tower (maybe a tubing upper half for height) and & get some readings from locals compared to my starduster. Then maybe a 5/8 wave tubing vertical (get some readings) and then just try some wire 5/8 wave long sloping radial skirts and see if there are any improvements after fiddling with the matching network.

I really need to get offa my butt and make a tilt up mast like you have and save myself a few trips up the tower.
