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:

It worked very well.

Subject: [amsat-bb] circular polarization of antennas not on same axis

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?
