Zach, all,

You'll also need an antenna.  Surprised that's not been mentioned in
this drift into homebrewing...

Before I got my 30 element Beam at a swap meet, I was using a homemade
17 turn Helix.  It was easy to make, and worked quite well.  I would not
say that the beam was any better, especially since the helix is
circularly polarized.  I still have it, and may swap it back into
service some day.
