[Netstumbler] will close cards cause interference?

["Carl Karsten" <carl@xxxxxxxxxxxxxxxxx>]

I plan on driving around with 2 or 3 NS laptops and compare results.  I was wondering if having the cards (therefore antennas) back
to back (inch or so that you get when you stack laoptops) would cause problmes?  actually, I am sure they will.  Wondering if anyone
knows how far apart they should be.
