I’ve been meaning to do this for a while: toss together a cheap Yagi antenna suitable for listening to AO-51 on 70cm. If you just google for “cheap yagi”, you’ll find the link to the design. An hour, some 12 gauge aluminum (not optimal, but what I had on hand), a poplar stick, some coax and hot glue, and voila. I have an antenna! Now all I have to do is wait for something to come overhead to see how it works.

Addendum: It works pretty darned good. Maybe just a little worse than my Arrow, but that’s just a guess. I was listening to N6PAA on the QRP repeater on AO-51 just a few minutes ago, and his signal was good and strong.
