Yes, it can be done. The "Satellite Experimenters Handbook" describes it. I have done it with Arrow antennas.
Here are a couple pictures from our 2005 setup: http://www.w0wtn.org/img_browse.php?i=/images/field_day_2005/p0000016.jpg http://www.w0wtn.org/img_browse.php?i=/images/field_day_2005/KK0SD_Sat_Ant.j pg http://www.w0wtn.org/img_browse.php?i=/images/field_day_2005/p0000017.jpg
It worked very well.

I have 2 of the ELK antennas which I mount at 90 degree angle to each other and switch between as the satellite rotates. My question is:
Could I feed the two ELK antennas which are 4 feet apart, on the same boom and at right angles to each other, in quadrature phase and achieve circular polarization or perhaps decent elliptical polarization?
Thanks,
