More trouble than it,s worth?

I looked at the ca forum and none of the posted models were quite like the pdf.
So I tried my hand at modeling it, I came up with 15.4 dBi @ 585 MHz.
Pretty good but not phenomenal (like 27 dBi) so I won't be building one.
And my quest for a 20+ dBi DX antenna continues.
Quote:
the same shape can be scaled to operate on VHF channel 4 and would have the same gain. The antenna would be about 10 times larger.
Thanks but not an option for my location ,it would hang over the property lines.
BTW. I did run the model (not scaled) at 69 MHz. and got 3.4 dBi at 90 and 270 deg. accounting for a SWR of 9.7 means a dipole is much better.
If I still lived on 14 acres in the country I'd pound in some 6'6 fence posts and use electric fence wire and insulators and play with it. But for now I'll abandon this design and continue the quest.
Best I've found is 18.5 dBi any suggestions (no VHF needed as I'll build a custom cut yagi for ch. 4)
