Homer, I was reading this old thread looking for some information about the Sirio SD-27 antenna, and I noticed the comment above.

Since you've rebuilt your idea for the New Vector 4000, and it is producing much better analyzer results, can you now share with us what the issues were that overcame the issues you were scratching your head about, what made the difference?

Also, did you build one of these vertical SD-27 antennas or something like it in the past using a gamma match or did you direct feed it? If you know, either way, how did it look on your analyzer?
