Looking to build a 2 element quad. Found a reference to a PDL 2 Avanti here on this site. Copied the Owners Manual, thanks to who ever posted it. Built my "StarBuster" based on the StarDuster, and it works great. Have been researching the 2 element quad for next build and the PDL 2 seems to have those interesting loops and a gamma match. Wanting to build my quad in horz. rectangle shape to keep from having to install a antenna matcher, 75 ohm coax, or a ballun to reach the 50 ohm desired for 10/11 meter use. Would the PDL 2 design be worth incorporating into my build? Would the gamma allow me to tune with out loss and maintain the square configuration? Does anyone know or can explain what advantage this gives to the quad?
