[amsat-bb] L Band antenna recommendations?

Hi David,

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... :-)
