I have read a circularly polarized Yagi is appropriate for ARISS
communications. Is there a vendor that offers a crossed design? Or, better
still, is there a construction article that I can refer to?

What are you using for this type of communication?

I'm trying to set up a contact for my son's school class.

Hi Steve

Have you contacted the AMSAT guys (www.amsat.org)? I assume you are
aware of the need for gain required for you particular station. I thought
a linearly polarized 3 or 4 element Yagi was adequate. So, I wonder if
the complexity of making a crossed Yagi CP is justified when that will have
only 3 dB improvement with that same boom length.

Jerry,

All news to me, so far. The ARISS website suggested circular
polarization and up to 100W. AMSAT is saying 3 elements and an HT. Quite
a variation...

Thanks for the hints, and I'll try listening for a while after I build
something!
