[amsat-bb] Making a Circular Polarized antenna

One of the ways to make a circularly polarized antenna is to feed two linearly polarized antennas in-phase, but mount one them 90 degrees rotated from the other, and 1/4 wavelength ahead of it.
Couldn't one also mount the two antennas 180 degrees rotated and 1/2 wavelength ahead?
The reason I ask is that I have some flat panel 2.4 ghz "Wi-Fi" antennas, and the mounting holes work out best that way.
The only effect I can think of is that the array will probably pick up signals from both left and right polarizations, which could actually be handy.
