[amsat-bb] CP antenna feed

There was an article written several years about feeding the cable off the end of a CP antenna versus running the cable up the boom the center with the results. Does anybody recall what edition of the Amsat Journal this was published?

I am looking to forward this is to new satellite operator to help with his decision. I spent 4 hours looking for that article and came up empty.

Thanks in advance, Tim - N8DEU
