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!

Hi Steve

AMSAT has special interest in schools. Have you read about that?
