Ok, in a little panic here... Building a helix to get a bit more gain on the AO-51 mode L uplink, and I just realized that I don't know if it should be Left or Right-hand polarized. Which way should it go?
Not sure which way will really matter, since the AO-51 L/S antenna is not circularly polarized. It's explained in Gould Smith's AO-51 book, and also in the following PDF:

Page 7 in the PDF has a photo of the antenna and a brief description of it.
73!
