Does anyone have any experience with the OWA design yagis. Is there any advantage other than low SWR and direct 50 ohm feed? I modeled the 15m 6el X 36' boom and compared it to my DX Engineering 15DX-6 with the same boom length and the DX Engineering had more gain throughout most of the band. Are there losses in the DX Eng. hair pin match or higher SWR that would make the OWA come out on top? 73, John
