I rolled my own from the VE3NPC design, and it works quite well and is
pretty portable actually. Details and pictures on my website at
http://n0jy.org click on the Satellite Antennas tab and you'll find a
link to the pdf right at the top of the description paragraph on the
satellite antennas page.
It was both fun and fairly easy to build, and I'm a very average builder
of anything hardware. I used a 3" piece of PVC pipe as the form to wrap
the turns, and if I recall correctly I just used the whole 25 foot roll
of copper wire I got from the hardware store so mine is a bit longer
than the design calls for. And when I was done winding I saw that I had
done it "backward" giving me LHCP rather than the desired RHCP! Must be
because I'm right handed and as I said, "average" or perhaps that was
overstated. I found that the wire did not like being unwound and
rewound so it cost me another roll of wire... :-)
