[amsat-bb] How to make phasing cable for 440 MHz Arrow II cross Yagi?

Hi. I have an Arrow II cross Yagi handheld antenna, but it doesn't come with a phasing cable to make it circularly polarized. I have some of the required components, but I can't find the guide I was using before. Can someone tell me how to make such a cable (or point me to a resource online)?

Thanks!
