2:1 Balun for 2 element cubical quad.

Hi, Anyone have a design for a 2:1 balun for a 2 element quad - I'm feeding it with 50 ohm coax.

Would a quarter wave matching stub (75 Ohm) be just as effective (coiled into a rf choke) ???

many thanks & 73

Hi Steve. if you designed the quad for 120 ohms, use the 75 ohm coax stub. It matches up without the loss of a balun and can be coiled to choke. Check the quad program for more info good luck
